Abstract

Techniques are described for managing program execution capacity, such as for a group of computing nodes that are provided for executing one or more programs for a user. In some situations, dynamic program execution capacity modifications for a computing node group that is in use may be performed periodically or otherwise in a recurrent manner, such as to aggregate multiple modifications that are requested or otherwise determined to be made during a period of time. The techniques may in some situations be used in conjunction with a fee-based program execution service that executes multiple programs on behalf of multiple users of the service.

Description

Law of causality is revised owing to the program executive capability and on-the-fly modified the program executive capability

Background technology

Many companies and other mechanism operate with the computer network of supporting its operation many computing systems are interconnected; Wherein for example said computing system colocated (for example; Part as localized network) or on the contrary be positioned at a plurality of different geographical (for example, connecting) via one or more special uses or public go-between.For example, the data center that the holds a large amount of interconnection computing systems nothing to be surprised at that become, such as by the operation of single mechanism and represent single mechanism the private data center and by as the physical operation of enterprise so that the shared data center of computational resource to be provided to client.The operator at some shared data centers provides access to netwoks, authority and safe installation to the hardware that each client had, and the operator of other public data center then provides " service (full service) comprehensively " facility of the hardware resource that comprises that also its client can use.Yet, along with the scale at typical data center and scope increase, provide, the task of domination and managing physical computational resource become complicated day by day.

The appearance of the Intel Virtualization Technology of commercial hardware provides some benefits about the managing large scale computational resource to a plurality of users with different demands, thereby makes various computational resources effectively and safely to be shared by a plurality of users.For example; Can make the single physical computing machine between a plurality of users, shared through one or more virtual machines (being provided by the single physical computing machine) are provided to each user such as those Intel Virtualization Technologies that provide by VMWare, XEN, Linux ' s KVM (" kernel level virtual machine ") or User-Mode Linux; Wherein every this virtual machine is the software simulation as the Different Logic computing system; The illusion that this logical calculated system provides to the user is that they are the unique operator and the keeper of given hardware computational resource, and application isolation and safety also are provided between each virtual machine simultaneously.

Embodiment

The technology that the program executive capability of the program that is used to carry out one or more users is managed has been described.In at least some embodiments, the program executive capability of being managed comprises the one group of one or more computing node that supplies the user to be used to carry out one or more programs.In addition, can on-the-fly modify during use and user-dependent this set of calculated node, so that the amount of the program executive capability that leading subscriber can obtain from this set of calculated node.To (for example having various forms with being modified in each embodiment of user-dependent this set of calculated node; To revise the quantity of computing node in this group; For example through dynamically adding and/or the deletion computing node); And in each embodiment, can cause in every way (for example, based on by the dynamic instruction of user's appointment, based on the trigger of consumer premise justice satisfy the confirming automatically of situation, based on the automation mechanized operation of the service that this set of calculated node is provided etc.).Below comprise other details that on-the-fly modifies about the program executive capability that can from a set of calculated node, obtain.In addition; In at least some embodiments; These technology can combine to represent a plurality of clients of this service or program that other users carry out a plurality of programs to carry out service (" PES ") to use; Carry out service such as the access to netwoks program, it provides a plurality of computing nodes (a plurality of physical computing systems and/or the virtual machine that for example, in one or more physical computing system, provide) of the program that is used to carry out the long-distance user.In these technology some or all also can carry out service system manager module and/or program and carry out the embodiment of service ability maintenance manager module and implement automatically through program, as described in greater detail below.

As previously mentioned, in each embodiment, on-the-fly modifying of carrying out can have various forms and can cause in every way to a set of calculated node of one or more programs of being used to carry out the user.As an instance; The program executive capability of this set of calculated node can be at least in part through measuring for the quantity of a part of computing node of this group; And can (for example revise through the computing node quantity that changes this group; Improving the program executive capability, and reduce the program executive capability) through reducing computing node quantity through increasing computing node quantity.This type of computing node quantity is revised the some or all of computing nodes that can be used in (for example) this group and is provided and (for example maybe can obtain identical or similar quantity Calculation resource; Amount of ram, hard drive space, CPU performance period, the network bandwidth etc.) situation in, make the given percentage change of computing node quantity corresponding to the total computational resource of this group and the identical or similar percentage change of program executive capability.In other embodiments; In this set of calculated node some or all can one or more important way aspect the amount of its obtainable computational resource different (for example; If use two kinds or the configuration of more kinds of dissimilar computing node; If each computing node all is independent of other computing node configuration etc.) or otherwise different aspect the type of its program executive capability that provides (for example; According to the type of specialized hardware, software program etc.), but the program executive capability of this group on-the-fly modify really can be at least in part based on the quantity of revising this set of calculated node, or on the contrary can be (for example based on alternate manner; With one type computing node configuration change is another kind of type), discuss in more detail like other place.

In addition; In at least some embodiments and situation; The program executive capability of one group of one or more computing node can be different from the mode of the quantity of computing node and measure and revise; The total amount (for example, amount of ram, hard drive space, CPU performance period, the network bandwidth etc.) of the computational resource of one or more types that for example provide based on this group.In addition; In at least some embodiments; Measuring and specifying in the program executive capability of a set of calculated node and can consider other factors; Such as the geographic position of some or all of computing nodes, between the some or all of computing node mutual relationship (for example, by maximum geographic distance at the most or at least the minimal geographical separating distance, by maximum network time-delay at the most or at least the minimal network time-delay separate, be separated into two or more independently data center or other computing node set that can not lose efficacy simultaneously etc.), the availability of specialized hardware ability and/or software capability etc.Below comprise other details about measurement and designated program executive capability.

PES or other system that one set of calculated node of one or more programs of being used to carry out the user is managed can confirm automatically that how and when in every way this computing node group being carried out the program executive capability on-the-fly modifies.For example; In at least some embodiments and situation; PES or other system can direct mode carry out the program executive capability modification of some type; And the program executive capability of other type revise can regularly carry out in other words conj.or perhaps with mode repeatedly carry out (for example, so as to postpone and be aggregated in a period of time (for example beginning before revising) from carrying out the one or many polymerization to be made through request or repeatedly modification of otherwise confirming.If a plurality of program executive capability of polymerization are revised determined value in a period of time, then the information about polymerization modification determined value can be used for improving in every way the enforcement that the program executive capability is revised.For example; If the program executive capability of confirming for twice corresponding to the modification of opposite types (is for example revised; To increase and to reduce computing node quantity, increase and the available total internal memory of minimizing etc.); Then twice modification can be carried out polymerization in every way, for example select partially or completely to cancel out each other through warp, or opposite to selecting the higher priority in twice pending modification to replace another time modification.In addition; If program executive capability that twice or more times are confirmed corresponding to the modification of similar or complementary types (is for example revised; So that computing node quantity increases specified amount, make available total internal memory increase specified amount etc. comprehensively comprehensively); Then those modification polymerizations likewise in every way of confirming (for example; The modification of confirming with the single of selecting to meet some specified value, such as maximum modification, minimal modifications, have the modification of limit priority, the modification of at first confirming, the modification confirmed at last etc.; To accumulate various definite modifications and to use the index word of accumulating; Deng).Below comprise about confirming how and when to make other details that each class method executive capability is revised.

In addition; A set of calculated node of representative of consumer being carried out one or more programs when PES or other system dynamically carries out the program executive capability when revising, and PES or other system can further carry out law of causality information or other attribution of responsibility of various operations with program executive capability modification that will be specific.Attribution of responsibility can comprise the particular event that (for example) identification has taken place in the relevant period; Wherein each incident can cause that all the program executive capability on-the-fly modifies, and with one in these incidents or many owing to during this period the program executive capability of carrying out afterwards in on-the-fly modifying some or all.For example; In at least some embodiments and situation; Some program executive capability on-the-fly modify separately and can (for example be caused by single particular event; If this set of calculated node failure becomes unavailable in other words conj.or perhaps, then system starts to this group immediately automatically provides alternative computing node, and the computing node unavailability becomes and causes that directly system's auto-action is to provide the individual event that substitutes computing node simultaneously).In at least some embodiments and situation; Other program executive capability on-the-fly modifies the combination that is attributable to a plurality of incidents separately; Each part in these incidents all helps or has the ability of helping (for example to revise; If a plurality of independent events need in each comfortable a period of time or indicate the computing node quantity of this group to increase; And when this period finishes, to increase the quantity of single computing node, each independent event becomes and causes indirectly that jointly the follow-up auto-action of system is to increase a plurality of incidents of computing node quantity these incidents simultaneously through polymerization).

The attribution of responsibility that the specific program executive capability of carrying out with user-dependent computing node group is on-the-fly modified can have special benefit under following situation; For example revise at least some program executive capability and when the user charges (for example, if PES or other system for since provide this group each computing node, program executive capability each other tolerance and/or based on other according to charging system to the consumption user charge).Under this type of situation; The user can receive and check about on-the-fly modifying the information of corresponding expense with the specific program executive capability; And can receive and check relevant attribution of responsibility information, so that the user can confirm reason and appropriateness that those program executive capability on-the-fly modify.In at least some these type of embodiments, attribution of responsibility information can people's readable format produces so that show to the user, so that the user can understand the explanation why each auto-action is taked by PES included in people's readable information or other system.In other embodiments, also can use this type of attribution of responsibility information by various alternate manners (comprising PES or other system) through starting other operation automatically.In addition; In at least some embodiments; Can produce and/or use attribution of responsibility information in response to all kinds of inquiries that receive from user or other source, these inquiries are such as being to cause that indication takes place one group of one or more computing node availability specific program executive capability is revised or the request of the reason of other variation and/or about which (repeatedly) program executive capability is revised or (a plurality of) change in availability of other computing node group is caused by the incident of one or more indications request about discerning which (a plurality of) incident.Below comprise other details about the attribution of responsibility information of confirming to on-the-fly modify with the service routine executive capability.

Under various situation, being used for the said technology that automatic supervisory routine executive capability on-the-fly modifies can provide various benefits.For example; On-the-fly modify to take all factors into consideration through request or definite program executive capability through polymerization is a plurality of; Perhaps, PES or other system can optimize how to carry out the polymerization modification; And with the minimize variations repeatedly of computing node, this can make the some or all of computing nodes that carry out extra variation temporarily unavailable in a period of time.In addition; But user's predefine is based on all kinds of triggers of the Performance Characteristics of a set of calculated node; Simultaneously when certain triggers is satisfied; Automatically improving or reduce the program executive capability according to circumstances (for example, improves the program executive capability of a set of calculated node with passive (reactively), thereby satisfies the temporary increase of the calculated load of computing node group; Initiatively (proactively) improves or reduces the program executive capability of a set of calculated node; Thereby the anticipated demand and/or the satisfied anticipated demand that is about to occur that has the program executive capability now that are about to occur that satisfy other program executive capability lack, and for example basis is about the time dependent trend of the historical data of the repeated use pattern of particular performance characteristics and/or instruction program executive capability; Deng).Perhaps; The user can hope that the program executive capability with a set of calculated node (for example remains near specified level or its; The required constant of the appointment of computing node); And can carry out various modifications automatically the available programs executive capability is remained on this specified level (for example, returning to this appointment aequum) to this set of calculated node will depart from the actual computation number of nodes of specifying aequum.For example the different duplicates of the execution of each in this set of calculated node same program (for example; With alternative form) as the total calculating load in this group; And during the workload that the quantity of revising computing node is handled by each computing node with management; Can use this type of technology; In other words conj.or perhaps these technology being used for each computing node of one group does not carry out in the situation of different duplicates of same program (for example, if the different subclass of this set of calculated node are carried out the duplicate of distinct program separately, for example so that some computing node is carried out application server programs and make other computing node carry out relevant database server program separately; If some in these computing nodes or all such as the different piece of implementing single program with distributed way; Deng).In addition; When group is added the additional calculations node; PES or other system also can randomly take other action in some situation at least; The computing node that is for example added to provide prepares to carry out one or more programs, or on the computing node that is added, further causes one or more program implementation automatically.

As previously mentioned, but user's predefine all kinds of triggers relevant with the program executive capability that on-the-fly modifies many set of calculated node, and the corresponding program executive capability robotization that those triggers can be used for causing user's computing node group subsequently on-the-fly modifies.As an instance; The trigger of the specific aequum of definable appointment computing node or the required total amount of one or more computational resources; For example it can be used for corresponding computing node group is remained on required computing node quantity or required computational resource total amount automatically, or is used to change the computing node quantity or the computational resource total amount (if satisfying specified value) of appointment on the contrary.In other situation; Definable is specified the trigger specific absolute or that change relatively of the computing node quantity or the total amount of one or more computational resources; If for example the Performance Characteristics of one or more indications of computing node group reaches assign thresholds or perhaps satisfies specified value; Then it can be triggered and (for example, remain in the specified scope of set period; The expression particular tendency, such as the appointment variable quantity in the set period, or such as specific " acceleration (acceleration) " or rate of change; Meet or corresponding to one or more designated modes the historical data of the repeated use pattern of representation program executive capability (for example from); Satisfy other combination of the appointment logical OR value of multiple Performance Characteristics, for example can use logical operator (such as AND, NOT, OR etc.) and/or otherwise with its combination; Deng).In other embodiment and situation; Predefined trigger can otherwise be satisfied according to the information of the Performance Characteristics that does not belong to the computing node group (for example, based on the current time that meets one or more fixed times (for the part of the standard of certain triggers or all); Be based on the status information of one or more programs of carrying out on the current computing node group of measuring with the mode that is different from Performance Characteristics, such as the current calculated load of representing as workload known in other words conj.or perhaps by (for example) or that expectation is accomplished by one or more programs through arrangement; Performance Characteristics or other status information based on one or more other executive routines of not carrying out by current computing node group; If mutual these programs of supporting in other words conj.or perhaps of for example current computing node group and other executive routine; So that when the calculated load on other executive routine increases or reduces, for example improve the program executive capability of current computing node group; Deng).This type of Performance Characteristics can based on the one or more any measurable attribute in this set of calculated node or with corresponding other yardstick of the operation of these nodes; Comprise following nonexcludability inventory item: the absolute or relative use amount of one or more computational resources of single computing node (for example, the percentage amounts of employed free memory or cpu cycle utilization factor, the employed network bandwidth absolute magnitude etc.); Definitely or relatively total use amount of one or more computational resources of all these set of calculated nodes; In response to measuring from absolute or relative time delay (latency) or other delay (delay) in the communication of outside computing system; Absolute or the relative inefficacy amount of computing node in accomplishing one or more required actions; Deng.In addition; In at least some embodiments and situation; The situation that satisfies of trigger is not that the specific program executive capability that the direct appointment of this trigger will be taken place when being satisfied is revised; But can make appointing system or module obtain notice, and this system or module can be asked to carry out specific program executive capability and revised that (for example, unaltered predefined ability is revised; The ability of for example dynamically confirming when notifying based on condition is at that time revised; Deng).In addition; In some embodiments; PES or other system can carry out various operations to monitor a set of calculated node; So that confirm the some or all of Performance Characteristicses of the trigger relevant with this group, or can be otherwise from the Performance Characteristics of another source this type of monitoring of acquisition (for example, from the third party software of monitoring said computing node, from the computing node execution to monitor this computing node and randomly to report the software etc. of monitoring information).In addition; In some embodiments; PES or other system can have the system definition trigger that the initiator executive capability on-the-fly modifies when satisfying the indication trigger criteria of trigger, or can under particular cases, otherwise confirm the computing node group is made the variation of some type automatically.

Specify the specific absolute or variation relatively of the computing node quantity or the total amount of one or more computational resources when the trigger of definition; And when confirming to satisfy one or more specified value of trigger of definition automatically based on the present case of corresponding computing node group, PES or other system can determine whether automatically that with how the program executive capability of trigger being carried out appointment revises.For example; Can carry out the designated program executive capability of some type immediately (for example revises; Stop using the request of one or more computing nodes, specified the request of the trigger that is used for implementing immediately etc. based on the user); Be deferred to the polymerization period when finishing and can the designated program executive capability of other type be revised, a part of revising with the repeatedly program executive capability that it is regarded as the polymerization that request is confirmed in other words conj.or perhaps during this period.Similarly; The type that for example on-the-fly modifies based on the program executive capability, based on from the user immediately or the explicit request of postpone implementing etc.; Can confirm by the program executive capability of user's dynamic requests revise (for example, via GUI, the perhaps graphic user interface of PES or other system; Through user program via the API of API or PES or other system of definition; Deng) to carry out immediately and/or temporary delay and polymerization in a similar fashion.In addition, when confirming how to manage the combination of definite repeatedly program executive capability modification, in some cases, different priority can be relevant with the different modifications of confirming.If so; For example for (for example giving the priority different with the trigger that is satisfied; User's request of dynamic appointment higher or lower priority) or other user instruction, the dissimilar warp of giving different priorities are confirmed (for example to revise; For for request that the reduction program executive capability of giving higher priority is compared in the request that improves the program executive capability) etc., this type of priority can be assessed in every way.Below comprise about using other details of user-defined trigger and definite Performance Characteristics.

In addition; In at least some embodiments; Based on a plurality of attributes of following the trail of and using corresponding computing node group; In other words conj.or perhaps based on separately all with this group in the relevant controllable parameter of one or more computing nodes, PES or other system can manage regularly the definite program executive capability modification of the repeatedly warp of polymerization repeatedly in other words conj.or perhaps.As an instance; With the computing node quantity of computing node group as with the corresponding yardstick of program executive capability of this computing node group; PES or other system can keep and use at least three kinds of tolerance that are mutually related to this computing node group; Be described below: the required computing node quantity of computing node group; For example when starting this computing node group, the associated user can carry out initial setting to it, and this quantity can be asked to revise according to the user who satisfies situation and/or dynamically appointment of trigger; The actual computation number of nodes of current available computing node in this group (for example, through confirming) to monitoring continuously or repeatedly of this set of calculated node is next; Computing node quantity (for example, confirm, and randomly upgrade through monitoring continuously or repeatedly frequently) with the offical record of current available computing node in this group as causing one or many program executive capability the last time and on-the-fly modify time.The a plurality of attributes of this type of of said computing node group (for example can be used for quantity that (for example) measure actual quantity continuously or times without number and upgrade offical record thus in every way; Based on this set of calculated node is monitored); And being used for regular the trial upgrades the quantity of nearest offical record to meet current requirement (for example, when considering how and whether will confirm that modification is made up to the warp of repeatedly polymerization).

As previously mentioned, PES or other system can further carry out law of causality information or other attribution of responsibility of various operations so that the specific program executive capability of making is on-the-fly modified.For example; As previously mentioned; The traceable corresponding incident of request that on-the-fly modifies with the program executive capability computing node group; The dynamic instruction and the predefined trigger that comprise the user's appointment that is received through confirming automatically to be satisfied, and the action of being taked automatically by PES or other system in some embodiments is (for example, based on the monitoring of carrying out; If for example confirm that computing node is frozen or perhaps be not useable for carrying out required activity, close or perhaps stop computing node is used as the part of its current computing node group automatically).Similarly, the actual change of the program executive capability of pursuitmeter operator node group likewise, such as with event and/or the corresponding variation of other capacity variation (for example, computing node lost efficacy the disabled example that becomes in other words conj.or perhaps).As an instance, can the variety of event relevant information be stored in first database table, and can with about the various information storage of capacity variation or other change in availability in second database table.If the relation between identification particular event and the specific change in availability (for example; Particular event causes specific change in availability to take place immediately), then can be through identical pass knot relevant identifier is tied with preserve the corresponding pass of following the trail of between said incident and the change in availability about the out of Memory of this incident and this change in availability.Can cause specific change in availability alone or in combination but law of causality not in other situation owing to individual event in a plurality of incidents; Can be with single pass knot relevant identifier with storing about each the out of Memory in said change in availability and those incidents, and can preserve (if they similarly can alone or in combination owing to those identical a plurality of incidents) together with out of Memory about one or more other change in availability.Therefore; If a plurality of incidents of for example given computing node group occur in during the single polymerization period and the variation of one or more program executive capability occurs in during this identical polymerization period or (for example be right after generation thereafter; Part as the Coordinating Activity that when this polymerization period finishes, carries out); And if those incidents are all not directly owing in said one or more capacity variation any one, then the combination of all these a plurality of incidents all is attributable to each in said one or more capacity variation.Below comprise further details (comprising B) with reference to Fig. 2 about this law of causality attribution.

In addition; In a similar fashion; A plurality of this type of is required, actual and formal attributes can be followed the trail of and be used for and corresponding one or more other controllable parameters of the program executive capability of computing node group, such as required first group, the cpu cycle overall average utilization factor of actual and positive formula weight, required second group, the network bandwidth overall average utilization factor of actual and positive formula weight etc.In addition; When following the trail of simultaneously and during the corresponding a plurality of parameter of the program executive capability of use and computing node group; PES or other system can attempt managing all parameters; For example revising the computing node group, so that obtain required cpu cycle overall average utilization factor and required network bandwidth overall average utilization factor simultaneously.As another instance; Computing node quantity and specified geographic location that a plurality of parameters of computing node group can comprise each computing node in this group are (for example; Between this set of calculated node of first data center 15% and 20% between; Remaining this set of calculated node is positioned at one or more other data centers), PES or other system attempt managing simultaneously the computing node quantity and the computing node geographic position of this group simultaneously.Below comprise about using a plurality of attributes to follow the trail of and manage other details of one or more program executive capability parameters.

In addition, in each embodiment, PES or other system can make the user visit computing node in every way.For example; In some embodiments; Can at least some of the computing node that can obtain from the PES that is used for executive routine be distributed to one or more users,, make among those users each can preferentially use those computing nodes with respect to other users so that those users can preferentially use.In this embodiment, these users' priority access can be based on each user of those computing nodes (for example to be similar to the mode of renting) that can proprietary or exclusive use set period.In addition; In some embodiments; When the user who for example is not assigned with these computing nodes when computing node uses and/or when the user who is assigned computing node makes clearly that the distribution calculation node can have been used by other users, distribute to one or more users and can be used as excessive program executive capability sometimes with in the computing node of proprietary or preferential use at least some and supply other users to use.Like this; At least some program executive capability of distributing to first group of user can be used for (for example on the basis of non-assurance) sometimes and represent other users (for example to come temporary transient executive routine; This program executive capability is used for other purpose if desired; Preferential or reservation such as one or more other users is used, and then makes the right to use of excessive program executive capability to be cancelled).In addition; In some embodiments; PES can comprise the on-demand computing node, its can be used for satisfying user's executive routine dynamic reception request (for example, when those users ask, the indication future time, the indication period in future in execution such as a period of time); Make and to carry out the indicated one or more programs of this request, when its prerequisite is near the computing node of execution when the time of being asked (or) that is enough to satisfy request available (but do not guarantee can satisfied this request).In addition, in some embodiments, this that (or predetermined) carries out immediately asks to be satisfied and to represent each user successfully to cause after one or more program implementation as required; Can guarantee to continue to use the on-demand computing node up to certain time in the future; Such as each certain user-selected time, certain time that randomly receives some restriction, (for example; Should guarantee that PES can not occupy the purposes of other purpose earlier, but not guarantee that the computing node of executive routine can lose efficacy).In some embodiments; Being used to provide as required, the computing node of variable program executive capability can be different from the computing node that is used to that the computing node of proprietary program executive capability is provided and/or is used to provide excessive program executive capability; Therefore if be not used for providing some of computing node of variable program executive capability as required; Then in some embodiments, these nodes can be used for providing excessive program executive capability, up to receiving variable program executive capability request as required; And in other embodiments, these nodes possibly not be used in provides excessive program executive capability.In other embodiments, the program executive capability of single type only can be provided, and/or the program executive capability of other type can be provided.

Figure 1A illustrates the network chart that the program that the computing node that can be used for providing the program of program executive capability to carry out a plurality of users is managed is carried out the instance of service.For the purpose of describing property, some instances and embodiment have below been described, wherein provide and manage the program executive capability of particular type with ad hoc fashion.In addition; In in following instance and embodiment some, the program executive capability that is provided by a set of calculated node can ad hoc fashion the quantity of computing node (for example, based on) measures; Can ad hoc fashion (for example; Required through following the trail of, actual and formal attribute is with respect to the purposes of one or more program executive capability yardsticks) manage, can through the associated user in every way (for example, based on the predefine trigger and/or the dynamic purposes of designated order) control; Can ad hoc fashion (for example make amendment; Revise through being aggregated at least some program executive capability of confirming in a period of time and postponing, when this period finishes, carry out the corresponding polymerization of one or many then and revise, for example to revise the quantity of computing node in a group) etc.Provide these instances to be used to the purpose of describing property and for the sake of brevity and with its simplification, and be to be understood that technology of the present invention can be used in various other situation, and following some that only described in these situation.

In the instance of Figure 1A; Each user's (not shown) is used for each client computing system 130 to carry out alternately with the PES that provides entity 105 to provide by program execution service through network 100; Some functions of PES are provided in this instance through the illustrated embodiment of program execution service system manager (" PESSM ") module 110 simultaneously, and the illustrated embodiment that other function is carried out service ability maintenance manager (" PESCMM ") module 115 through program is provided in this instance.PESSM module 110 can for example help the specific user to dispose to be ready to use in to carry out many set of calculated node of these users' program, is included as these groups and specifies initial required computing node quantity and appointment to be used for subsequently computing node quantity being made the trigger that on-the-fly modifies automatically.In this example; PES makes each computing node 120 can be used for carrying out user's program; But in other embodiments; At least some that are used at least some computing nodes of organizing can otherwise provide (for example, can provide such as outside computing system 140 through user and/or third party, but managed by PES).In addition, PESCMM module 115 can help continuously or monitor computing node group in use repeatedly, and randomly trial replaces losing efficacy or perhaps the disabled any computing node that becomes, so that the program executive capability is remained on before definite level.

Network 100 can for example be the disclosed accesses network of linked network, and it possibly operated by different each side (such as the Internet).In other embodiments, network 100 can be private, such as non-the superuser completely or partially enterprise network or the campus network of inaccessible.In other embodiments, network 100 can comprise internet accessible and/or can be through one or more private of access to the Internet.In illustrated embodiment, PESSM module 110 can be included in the software instruction of carrying out on one or more computing system (not shown) separately with PESCMM module 115.In addition;

In addition, PESSM module 110 can be carried out other activity, changes to follow the trail of to event of specific calculation groups of nodes and specific program executive capability.At least some program executive capability change informations can with cause by module 110 to on-the-fly modify corresponding as the program executive capability of the part of Coordinating Activity regularly or repeatedly; And randomly also can comprise in some cases in the monitoring of being undertaken by PESCMM module 115 program executive capability change information (for example; With become in other words conj.or perhaps corresponding to inefficacy disabled computing node or institute's change detected of other type of the program executive capability of computing node group).Module 110 also can be for example according to carry out regularly or other repeatedly Coordinating Activity carry out confirming automatically in each time (or on the contrary At All Other Times), with law of causality that certain capabilities is changed or other attribution of responsibility in particular event.

Though the above-mentioned exemplary to providing the PES of types of functionality to describe Figure 1A to each user is to be understood that to have various other embodiments.For example; In at least some embodiments; The not use part of single computing node 120 (for example; The not use of untapped processing unit clock period, internal memory part etc.) can supply one or more users to use, make the user that wins one or more programs can with the resource of one or more other users' the single computing node of those procedure sharing.In addition, though carry out service and the program executive capability has been described some embodiments, be to be understood that said technology can be used for managing the right to use of the calculating related resource of each other set of calculated node or other type to program.The nonexcludability inventory item of the instance of the calculating related resource of other type that can use for a plurality of users through management can comprise following content: persistent data storage capacity (for example, at non-volatile memory device, on hard disk drive); Ephemeral data storage capacity (for example, in volatile memory, on RAM); Message queueing and/or transmission capacity; The communication capacity of other type (for example, network socket, virtual communication circuit etc.); The data base administration ability; Proprietary bandwidth or other network related resource; The input media ability; The output unit ability; Cpu cycle or other instruction executive capability; Deng.

Figure 1B shows and wherein can adopt the one or more data centers that comprise a plurality of physical computing system to provide program to carry out the embodiment of service.Specifically, Figure 1B illustrates PESSM module 180 that program wherein carries out service and PESCMM module 160 to adopt each computing system at said one or more data centers place to come the network chart of exemplary of one or more program implementation of Management Representative user.Illustrated example comprises the data center 170 that PES uses, and data center 1 70 is connected to the Internet 196 of data center 170 outsides.In this example, the Internet 196 provides the right of the various outside computing systems of visit, such as via the computing system 190 of private 194 and the computing system 192 that can directly visit.Private 194 for example can be from the outside non-franchise computing system of private 194 enterprise network of inaccessible completely or partially.Computing system 192 can comprise the family expenses computing system that for example is connected directly to the Internet (for example, via phone or cable modem, digital subscriber line (" DSL ") etc.).In addition, show one or more other data centers 198 that are connected to data center 170 via the Internet 196, for example data center 198 can further be used by PES at least some embodiments.

Exemplary data center 170 comprises many physical host computing system 175, physical computing system 182, the PESSM module 180 of PES and the PESCMM module 160 of PES.In this example; Host computing system 175 provides a plurality of virtual machines separately; And manager component (for example to have the virtual machine (" VM ") of managing those virtual machines; Supervisory routine or other virtual machine monitor), for example shown to host computing system 175a with a plurality of virtual machine 177a and VM manager component 179a.Other host computing system 175b can likewise comprise this class component; For the sake of brevity; Not shown here those other assemblies, and some or all of computing system 182 can randomly have one or more these type of virtual machines and/or VM manager component (not shown) equally.In the virtual machine that is provided by host computing system each all can be used as different computing nodes and is used for PES; For example so that the first virtual machine computing node on the host computing system becomes the part of first user's the first computing node group, and make the second virtual machine computing node on the said same host computing system become the part of second user's the second computing node group.Perhaps, in other embodiments, some in the physical host computing system at said data center place or all any virtual machine possibly is not provided, the for example opposite computing node of directly carrying out one or more programs as the final consumption user who represents PES.In addition; In some embodiments, each computing system 175 and 1 82 all can have different ability, can have different relevant usage charges; (for example can support dissimilar user programs; The software image example of the virtual machine of different size, or have dissimilar resource criterion and/or computational resource utilization rate is such as the program of I/O and the storage access and the network usage of different mode) etc.If so, then can be according to one or more these type of factors to specific user and/or its program divide into groups (for example automatically), these factors also can be used as constraint condition and/or the preference of selecting computing system to carry out specific program.Exemplary data center 170 also comprises the internal network 172 that can comprise a plurality of interconnection device (not shown) (such as converter, edge router and core router), and the computing system 175 and 182, PESCMM module 160 and the PESSM module 180 that are connected to internal network 172.Each host computing system 175 all can be provided with other computing system 182 in every way, comprises through it being grouped in the frame of sharing shared base plate or other connected medium.In addition, can adopt one or more computing system (not shown) to come each in

execution module

160 and 180.

At least some that illustrated PESSM module 180 and PESCMM module 160 are implemented in the said technology are so that management executive routine on the many set of calculated node that adopts computing system 175 and 182 to provide is described like other place in more detail.When selecting the specific calculation node to carry out one or more program of user; In some embodiments; The PESSM module can be through beginning to carry out those programs with VM manager component or other manager component of controlling the program implementation of said selected computing node alternately, perhaps can be on selected computing node direct executive routine.The user of PES can use various computing systems, and such as

computing system

190 or 192, or the computing system that one of other data center 198 locates is to carry out with PESSM module 180 alternately.

Be to be understood that the data center of Figure 1B only is provided for illustrative purpose, and can otherwise provide program to carry out service and other software executing service in other embodiments.For example, can adopt outside one or more other computing systems of data center 170 on the contrary, PESSM module 180 and/or PESCMM module 160 are provided such as the computing system at computing system 190,192 or data center 198 places.

Fig. 2 A shows the instance of the technology that one group of example calculation node of the one or more programs that are provided for carrying out example user is managed, such as the technology that can be implemented automatically by the embodiment of PESSM module and/or PESCMM module.Specifically; In this example; Specific user (hereinafter to be referred as user UUU and not shown in Fig. 2 A) has brought into use one group of a plurality of computing node to carry out the duplicate of indicated program separately to represent this user; For example to be used as the request that service was received that computing node is handled to be provided by said executive routine that substitutes (for example, so that balance should be served the calculated load in the whole a plurality of computing nodes that should organize).Shown in timeline coordinate diagram 210, the user has asked the computing node group is provided in time T 1, and specifies initial required computing node quantity 215a for 8 computing nodes of this group.Information 250 is to each user-defined trigger indication, and the user specifies to the computing node group when initial request for example.In addition; Timeline coordinate diagram 205 shows about will being used for the computing node group and will being used for confirming the information of two kinds of example types of the Performance Characteristics whether trigger 250 is satisfied by tracking, and said information comprises the CPU overall average utilization factor 205a of computing node group and the network bandwidth overall average utilization factor 205b of computing node group in this example.

Incident E1 when asking corresponding time T 1 with the user who is received who begins to provide the computing node group, exemplary PES (not shown) starts the computing node group that comprises eight computing nodes at first according to initial required computing node quantity to the user.The computing node quantity 225 of the offical record of computing node group likewise is set to eight computing nodes in addition.Yet; Shown in timeline coordinate diagram 210; Said eight computing nodes are in fact not available immediately; Because need a period of time that these computing nodes are provided and make its part that can be used as the computing node group, comprise making on program duplicate each in these computing nodes and carry out through PES or user.Specifically, behind the initial time after elapsed time T1, the program executive capability of the computing node group C1 255 that changes, this variation finishes when whenabouts T2 when time T 1, and with available eight computing nodes in preceding four corresponding.Therefore, follow the trail of the actual computation number of nodes 220 that is used for the computing node group and increase to 4 from 0 in the said time.In addition, simultaneously or shortly after that, timeline coordinate diagram 205 shows, begins to follow the trail of the Performance Characteristics of CPU overall average utilization factor 205a and network bandwidth overall average utilization factor 205b according to the operation of available computing node in this group.

In this example, PES (or other third party system) monitors this set of calculated node with roughly continuous mode, the feasible information that keeps Performance Characteristics 205a and 205b and actual computation number of nodes 220 with up-to-date mode.Yet; In this example; Only regularly the computing node quantity of computing node group is carried out on-the-fly modifying of some type at least; For example with the modification through request of some type at least of polymerization during the polymerization period 260, and when the polymerization period between the computing node quantity 215,220 and 225 of required, reality and offical record finishes respectively, to carry out Coordinating Activity.Therefore, during the first polymerization period 260a, the computing node quantity amount of computing node group is outer to change 255.For example, after the variation C1 that preceding four computing nodes can be used, the follow-up variation C2 that when whenabouts T3, finishes is corresponding with three additional calculations nodes of a part that can be used as the computing node group.

Yet; In this example; For example because the hardware problem that the initial computing node of selecting exists (or on the contrary in other situation and since when time T 1 only 7 computing nodes can be used in the computing node group, wherein in case the 8th computing node is available subsequently; Just with its dynamic interpolation), the 8th computing node of initial request can not be in time available.Therefore; Showing incident E2 265 occurs in and changes after the C2 (when whenabouts T4) soon; Wherein PES stops original the 8th computing node (if desired) (for example, if it is frozen under the intermediateness), and begins to provide the 8th alternative computing node.As discussing in more detail with reference to Fig. 2 B; In this example; PES has caused the variation C10a when adding the corresponding time T 1 of the 8th initial computing node; But this variation C10a fails through adding and available the 8th computing node of reality accomplished, and therefore changes C10a and in the actual computation number of nodes 220 of timeline coordinate diagram 210, embodies, also not otherwise shown in Fig. 2 A.On the contrary, in this example, incident E2 is divided into simultaneously or approaching simultaneous two different events E2a and E2b (not illustrating separately).Specifically; In this example; The PES record incident E2a when failing the corresponding time T 4 of the 8th computing node of correct initialization (for example in fixed time limit), and the variation C10b (not shown) of PES when causing time T 4 automatically is to stop failing correct initialized the 8th initial computing node.In addition, in this example, the individual case E2b when the actual termination itself that the 8th initial computing node takes place owing to incident E2a is regarded as time T 4, the automatic initiation of individual case E2b provides the 8th alternative computing node immediately.In this type of link incident that itself can being regarded as as a result of making that the variation of the incident of winning causes causes another kind of second incident that changes and the mutual relationship of respective change result between track of events and respective change result various benefits can be provided, discuss in more detail like other place.Subsequently, when the time T 4, and the variation C3 255 that when time T 5, finishes makes the actual computation number of nodes become eight from seven according to incident E2b, because the 8th alternative computing node can be used as the part of computing node group.

After eight computing nodes of computing node group are operated the part of polymerization period 260a with the mode of expection; At whenabouts T7; The another kind of C4 255 of variation takes place in actual computation number of nodes 220, and this variation impels by one in the inefficacy or perhaps the disabled computing node that becomes.Corresponding event E3 265 and variation C4 take place approximately simultaneously, and wherein PES stops unavailable computing node (if desired), and randomly begins to provide alternative computing node automatically.Specifically, to be similar to the mode of being discussed to incident E2 before this, incident E3 is divided into simultaneously or approaching simultaneous two different events E3a and E3b (not illustrating separately) in this example.Therefore, PES writes down and incident E3a when detecting the corresponding time T 7 of the disabled computing node that become in this example, and the activity of PES when causing time T 7 automatically for example changes C4 directly to cause to stop unavailable computing node.In addition; In this example; The termination itself that unavailable computing node takes place owing to incident E3a is regarded as and when whenabouts T7, causes the individual case E3b that substitutes computing node to provide immediately automatically; But in other embodiment and situation, any this providing on the contrary that substitutes computing node will be postponed up to the Coordinating Activity H1 that when polymerization period 260a finishes, carries out.Subsequently, in this example, change C5 255 and when whenabouts T9, finish, this variation returns to eight with the actual computation number of nodes, and this is directly caused by incident E3b, because said alternative computing node can be used as the part of computing node group.In this example; The temporary transient computing node quantity 225 of not upgrading offical record is with corresponding to changing C4 and C5; Do not upgrade with corresponding to previous variation C1-C3 yet; But in other embodiments, the computing node quantity 225 of renewable offical record changes to reflect some or all of this type of, for example continuously or times without number the computing node quantity 225 of offical record is remained in the state consistent with the actual computation number of nodes that is upgraded 220.In this example, other computing node ability change in availability or incident taking place in all the other times of polymerization period 260a, comprises that the trigger 250 of all appointments is not satisfied, and do not receive the user instruction of dynamic appointment.Therefore, during time T 11 when said period 260a finishes, considered first group of Coordinating Activity H1, but need not any activity, because the computing node quantity 215,220 and 225 of current required, reality and offical record is all mated at eight computing node places respectively.If during polymerization period 260a, replace the variation C5 (shown in this instance) of unavailable computing node; Then after this polymerization period; This variation can be caused as the part of Coordinating Activity H1 on the contrary; So that replace the unavailable computing node (for example, being combined in any other dynamic change in availability of asking or causing during the polymerization period 260a) at place of said time.

Yet, during the second polymerization period 260b, other incident has taken place.Specifically; When incident E5 265 at first occurs in whenabouts T16; Thereby it is corresponding with automatically confirming of making of PES; Promptly through improving CPU overall average utilization factor 205a trigger TR-1250a is satisfied, such as in the timeline coordinate diagram 205 through first black on the CPU overall average utilization factor 205a line oval diagram.For 12 through the request whole required computing node quantity 215c for (perhaps regardless of current required computing node quantity; The required computing node quantity that can ask to be upgraded is set to 12), the situation that satisfies of trigger TR-1 has caused the request with 4 computing nodes of required computing node quantity 215 increases.Similarly; After passing through other extra time; When next incident E6 265 occurs in whenabouts T18; Thereby with confirm that trigger TR-N 250c is satisfied is corresponding through improving network bandwidth overall average utilization factor 205b, such as in the timeline coordinate diagram 205 through the black on the network bandwidth overall average utilization factor 205b line oval diagram.For ten through the request whole required computing node quantity 215d for (perhaps regardless of current required computing node quantity; The required computing node quantity that can ask to be upgraded is set to ten), the situation that satisfies of trigger TR-N has caused the request with 2 computing nodes of required computing node quantity 215 increases.After through short extra time; When incident E4 265 occurs in whenabouts T19; Wherein for 11 through the request whole required computing node quantity 215b for (perhaps regardless of current required computing node quantity; The required computing node quantity that can ask to be upgraded is set to 11), the user relevant with the computing node group provides the dynamic specified request that required computing node quantity 215 is increased by 3 computing nodes.Can be for example according to noticing that CPU overall average utilization factor 205a is that the user that total calculating load on higher, the computing node group is increasing etc. makes this request.

At last, soon, when extra variation C6 occurred in whenabouts T20, this variation impelled by one in the inefficacy or perhaps disabled this set of calculated node that becomes before polymerization period 260b finishes.Corresponding event E9 and variation C6 take place approximately simultaneously, and wherein PES stops unavailable computing node (if desired).In this example; Yet PES begins to provide alternative computing node immediately; But decision is waited for up to the second group of Coordinating Activity H2 that is about to carry out and (for example being begun during in time T 21; Provide according to a small amount of time remaining before the time T 21, according to this type of delay that substitutes computing node etc.; Said delay is the default-action of the disabled any computing node that becomes in use) because possible be the quantity that will reduce computing node in the computing node group according to those Coordinating Activities, and need not said alternative computing node.In other embodiments, PES can begin to provide alternative computing node (for example, to be based on and not postpone substituting of unavailable computing node in any case on the contrary immediately; Based on not postponing the substituting of unavailable computing node (because required computing node quantity possibly increase as the part of Coordinating Activity H2 but not reduce) in this case; Based on substitute (because other factors was paid to eight computing nodes before time T 3 after a while such as the user) that does not postpone unavailable computing node in this case; Deng).Specifically, to be similar to the mode of being discussed to incident E2 and E3 before this, incident E9 is divided into simultaneously or approaching simultaneous two different events E9a and E9b (not illustrating separately).Therefore, PES writes down and incident E9a when detecting the corresponding time T 20 of the disabled computing node that become in this example, and the activity of PES when causing time T 20 automatically for example changes C6 directly to cause to stop unavailable computing node.In addition; In this example; Individual case E9b when the termination itself that unavailable computing node takes place owing to incident E9a is regarded as whenabouts T20; This incident causes the additional calculations node that will organize and is used as the request that substitutes computing node, for example required computing node quantity 215 is remained on the requirement 215a of eight computing nodes.In this example; Come the request of processing events E9b with the mode that is similar to incident E4-E6; This request is postponed up to will be at the Coordinating Activity H2 that when pre-polymerization period 260b finishes, carries out, but in other embodiment and situation, can begin alternative this of computing node on the contrary immediately provides.In addition; In this example; Not being similar to before this to changing computing node quantity 225 that mode that C4 and C5 describe upgrades offical record with corresponding to variation C6, but in other embodiments, the computing node quantity 225 of renewable offical record is to reflect this type of variation.

Therefore, when the second polymerization period 260b finishes, beginning Coordinating Activity H2, and can cause on-the-fly modifying in this case to the computing node group.Specifically; PES in this example will with incident E4, E5, E6 and E9b various through the request required

computing node quantity

215b, 215c, 215d and 215a corresponding through the request the modification polymerizations; And decision is revised the dynamic quantity that eight previous required computing node quantity 215a make polymerization; The dynamic quantity of polymerization is simultaneously revised (has for example increased by four additional calculations nodes in this example; Based on the maximal value that adopts in the quantity of request is revised) so that corresponding to 12 current required computing node quantity 215e that upgraded.In other embodiments; Can otherwise come to confirm the dynamic quantity modification of polymerization; For example revise so that (for example keep previous required computing node quantity 215a according to incident E9b with the dynamic quantity of selective polymerization; Thereby cause increasing a computing node from current actual computation number of nodes), the minimum value in revising with the quantity that adopts incident E4-E6 (for example, thereby cause increasing by two computing nodes) from current required computing node quantity through request; The mean value of revising with the quantity through request that adopts incident E4-E6 (for example; Thereby cause increasing by three computing nodes from current required computing node quantity), the polymerization value of revising with the quantity that adopts incident E4-E6 (for example, thereby cause increasing by nine computing nodes) from current required computing node quantity through request; The limit priority of revising with the quantity through request that adopts incident E4-E6 (for example; Thereby cause increasing by three computing nodes from current required computing node quantity, its prerequisite is that the trigger of for example comparing incident E5 and E6 satisfies situation, and the user instruction of E4 is regarded as has higher priority); The modification of the modification of request for the first time or last request in revising with the quantity that adopts incident E4-E6 (for example, thereby cause increasing by four or three computing nodes respectively) etc. from current required computing node quantity through request.The user instruction incident is compared trigger and (is for example satisfied in some embodiments and the situation that incident has higher priority therein; If user instruction can cover any on-the-fly modifying through request of satisfying incident from trigger all the time); PES can prevent that also other trigger from satisfying incident and occurring in during the polymerization period that receives after the user instruction incident, for example occurs in any trigger that receives after the user instruction to incident E4 and satisfies incident to ignore (or never definite) in this example.In addition, in this example, when Coordinating Activity H2, the computing node quantity 220 of current reality and offical record is different respectively with eight computing node places at seven with 225.Therefore; Part as Coordinating Activity H2; PES begins to the computing node group five additional calculations nodes to be provided; Seven current actual computation number of nodes being increased to 12 new required computing node quantity of upgrading, and the computing node quantity 225 of further upgrading offical record is to meet 12 new required computing node quantity of upgrading.Therefore; In this example; The ability change in availability of 5 computing nodes is caused by following mode indirectly: replace according to incident E9b owing to change the C7 disabled computing node that becomes, and increase and revise corresponding 4 additional calculations nodes from the determined polymerization quantity of incident E4, E5 and E6.

During trimerization period 260c, other incident and computing node ability change in availability further take place.Specifically; Changing C7 finishes when whenabouts T22; Wherein current available computing node quantity has increased by five to 12 computing nodes altogether, and with five additional calculations nodes that reflect that its availability begins when the time T 21, and actual computation number of nodes 220 is updated thus.Shown in timeline coordinate diagram 205, CPU overall average utilization factor 205a and network bandwidth overall average utilization factor 205b all reduce after changing C7, and wherein CPU overall average utilization factor 205a descends rapidly.Specifically; In this example; CPU overall average utilization factor 205a finally is brought down below the threshold value with the specified value of trigger 250b corresponding 20%; Thereby cause incident E8 that (comprise and confirm that trigger TR-3 250b is satisfied) takes place, such as in the timeline coordinate diagram 205 through second black on the CPU overall average utilization factor 205a line oval diagram.For ten through the request whole required computing node quantity 215f for (perhaps regardless of current required computing node quantity; The required computing node quantity that can ask to be upgraded is set to ten), the situation that satisfies of trigger has caused the request that required computing node quantity 215 is reduced 2 computing nodes.

At last, before polymerization period 260c finished, when extra variation C8 occurred in whenabouts T28, this variation impelled by one in the inefficacy or perhaps disabled this set of calculated node that becomes.Corresponding event E10 and variation C8 take place approximately simultaneously, and wherein PES stops unavailable computing node (if desired).To be similar to the mode that changes C6; PES selects to wait for up to the 3rd group of Coordinating Activity H3 during in time T 31 in this example, but not begin to substitute unavailable computing node immediately (for example, because incident E8 makes maybe or likelyly be; After this requirement of computing node can reduce in the computing node group); PES can begin to provide alternative computing node on the contrary immediately, specifically but in other embodiments; To be similar to incident E2, E3 and the described mode of E9 of being directed against before this, incident E10 is divided into simultaneously or approaching simultaneous two different events E10a and E10b (not illustrating separately) in this example.Therefore, in this example, PES record and incident E10a when detecting the corresponding time T 28 of the disabled computing node that become, and the activity of PES when causing time T 28 automatically for example changes C8 directly to cause to stop unavailable computing node.In addition; In this example; Individual case E10b when the termination itself that unavailable computing node takes place owing to incident E10a is regarded as whenabouts T28; This incident causes the additional calculations node that will organize and is used as the request that substitutes computing node, for example required computing node quantity 215 is remained on the requirement 215e of 12 computing nodes.In this example; Come the request of processing events E10b with the mode that is similar to incident E9b; This request is postponed up to will be at the Coordinating Activity H3 that when pre-polymerization period 260c finishes, carries out, but in other embodiment and situation, can begin alternative this of computing node on the contrary immediately provides.In addition; In this example; Not being similar to before this to changing computing node quantity 225 that the described mode of C4-C6 upgrades offical record with corresponding to changing C8, but in other embodiments, the computing node quantity 225 of renewable offical record is to reflect this type of variation.

Therefore, when trimerization period 260c finishes, beginning Coordinating Activity H3, and can cause the computing node group to change.Specifically; PES in this example will with the corresponding modification polymerization of incident (being merely incident E8 and E10b in this example) that occurs in during the period 260b through request; And decision is revised the dynamic quantity that 12 previous required computing node quantity 215e make polymerization; Said modification has reduced by two computing nodes in this example, so that corresponding to ten current required computing node quantity 215g that upgraded.In addition, when Coordinating Activity H3, the computing node quantity 220 of current reality and offical record is different respectively with 12 computing node places at 11 with 225.Therefore; Part as Coordinating Activity H3; PES causes 12 current formal computing node quantity according to the current actual computation node capacity of 11 computing nodes and changes; To reach ten current required actual computation number of nodes; From the computing node group, remove (for example, randomly after accomplishing the some or all of actions begun, terminating in executive routine on the computing node that has removed, and so that this computing node can supply other users to use in the future) so that will have one of computing node now.Therefore, in this example, when time T 31, will have the ability change in availability that one of computing node removes now and cause by following mode indirectly: stop a set of calculated node, and request reduce and corresponding 2 computing nodes of incident E8 about incident E10b.PES further upgrades the computing node quantity 225 of offical record to meet ten new required computing node quantity of upgrading.After time T 31 soon; The final C9 that changes finishes when whenabouts T32, and wherein current available computing node quantity has reduced one to ten computing nodes altogether, begins the computing node that from the computing node group, removes when being reflected in time T 31; And actual computation number of nodes 220 is updated thus; In other embodiments, when said variation is made in decision, change C9 and can occur in time T 31 basically immediately; For example its prerequisite be immediately will be to be removed computing node from other activity of computing node group, withdraw from, even when the computing node that has removed is temporarily carried out and can be used for proceeding to operate.

In addition, though shown in this example Coordinating Activity H1, H2 and H3 occur in single time point, be to be understood that in fact some or all of Coordinating Activities can occur in a period of time, and can have other effect of lasting a period of time.For example, at least some embodiments, the some or all of variations to the program executive capability of computing node group that caused by PES can produce the incident that possibly not allow at least some other types or the interim lockup period of variation.The program executive capability that can cause the PES-indication of this locking changes for example can comprise that the program executive capability that the part as Coordinating Activity causes (for example increases and/or reduces; Add new computing node, remove existing computing node etc.); And/or in response to PES decision (for example, computing node lost efficacy, received user instruction, user's appointment trigger satisfy situation etc.) and the program executive capability that causes immediately changes.This type of locking can have various types of duration that (for example, result or generation until appointment have for example become available up to the computing node that is added; The duration of appointment, become available average or expeced time such as the computing node that is added; Deng), and the type of the variation that can cause according to PES in some embodiments and different.Between this type of lockup period; Possibly not allow the incident or the variation of some type at least; For example do not allow the trigger of user's appointment during this Lockout Duration to be satisfied (or satisfy situation through ignoring any this type of trigger), and/or do not allow during this Lockout Duration, to accept user instruction (or through ignoring any this type of user instruction).In addition, in some embodiments, the user relevant with the computing node group can likewise specify with similar mode cooling cycle of operating locking cooling cycle, such as being right after locking or occurring in cooling cycle of fixed time amount At All Other Times on the contrary.As locking, during cooling, possibly not allow the incident or the variation of some type at least, for example be satisfied (or satisfy situation through ignoring any this type of trigger) with the trigger that does not allow user's appointment during cooling.Be to be understood that in other embodiments, user and/or PES can otherwise control the modification to the computing node group.

Therefore, like this, PES operation offers user's program executive capability with management by a set of calculated node, comprises according to various situation this computing node group is made variously on-the-fly modifying.Be to be understood that the incident shown in Fig. 2 A only is provided for carrying out schematic purpose with changing, and the said actual event of PES, variation operate in other maybe be different in other embodiment and the situation.

Fig. 2 B shows the instance of the technology that is used for cause-effect relationship information is on-the-fly modified owing to the computing node quantity of being discussed with reference to Fig. 2 A before this automatically, such as the technology that can be carried out automatically by the embodiment of PESSM module.Specifically; Fig. 2 B shows two instance database list data structure of some information corresponding in the information shown in storage and Fig. 2 A; Wherein the example table 280 of Fig. 2 B stores the relevant various information of example calculation node capacity change in availability that take place with the example calculation groups of nodes (being called " the 1st group " among Fig. 2 B) of Fig. 2 A, and the example table 290 of Fig. 2 B stores the relevant various information of exemplary event that take place with the example calculation groups of nodes (the 1st group) of Fig. 2 A.

Example table 280 comprises separately corresponding to each row or 285a-285k one of among the exemplary variations C1-C10 that is discussed with reference to Fig. 2 A, wherein shows each hurdle or the row 280a-280x of each row.Specifically; In this example; Each row comprises unique identifier (" ID ") 280a, the indication 280d of the type 280c that changes with the ID 280b that changes corresponding suitable computing node group, program executive capability, the expected results that the program executive capability changes, about the start and end time 280f and the 280g of the various details 280e that change, variation, change in other words conj.or perhaps with change relevant polymerization period 280h (in this example for being based on the mentioned polymerization period of Coordinating Activity that the polymerization period carries out when finishing), ID 280x and optional various out of Memory are tied in variations-incident pass.As an illustrative examples, row 285a changes the variation of C1 corresponding to the 1st group computing node quantity corresponding to the 1st group variation C1, and this variation relates to be increased by 4 computing nodes and finishing during in time T 02 during the polymerization period H1.Other row comprises similar information.

Example table 290 comprises separately corresponding to reference to each row or 295a-295m one of among the described exemplary event E1-E10 of Fig. 2 A, wherein shows each hurdle or the row 290a-290x of each row.Specifically; In this example; Each row comprise unique identifier (" ID ") 290a, with the type 290c of the ID 290b of the corresponding suitable computing node of incident, incident, about the time 290e of the information 290d of Event origin, incident, generation incident in other words conj.or perhaps with incident relevant polymerization period 290f (Coordinating Activity that carries out when referring to that in this example being based on the polymerization period finishes), variation-incident pass tie ID 290x and optional various out of Memory (for example, relevant specific user) with the user instruction that is received.As an illustrative examples, row 295h is corresponding to the 1st group incident E4, the user instruction that this incident E4 is received during corresponding to the time T 19 during polymerization period H2, and the required computing node quantity that this instruction request is the 1st group increases by 3 computing nodes.Other row comprises similar information.

In the instance of Fig. 2 B, table 280 and 290 variation-incident close knot id information 280x and 290x reflected by attribution change with reflection and incident between the cause-effect relationship information of relation.Specifically, in this example, share common value with 290x if the hand-manipulating of needle in the table 280 and 290 closes knot id information 280x to variation-incident, then its reflected between corresponding event and the variation by the cause-effect relationship of attribution.As an instance, such as before this with reference to Fig. 2 A discussion, incident E3b is corresponding to providing the alternative computing node that becomes disabled computing node, said computing node can be directly owing to corresponding to the variation C5 that thus computing node is added into this group.Therefore, going 295e (corresponding to incident E3b) and row 285g (corresponding to changing C5) shares common pass knot identifier.

On the contrary, with the corresponding variation of five computing nodes of the interpolation that during Coordinating Activity H2, begins C7 do not have can be directly owing to the individual event of this variation.Specifically, incident E4, E5 and E6 ask the 1st group is on-the-fly modified separately, and these on-the-fly modify through polymerization and are used for impelling add five computing nodes to changing C7 four jointly.Thereby row 295f-295h (corresponding to incident E4-E6) and row 285i (corresponding to changing C7) all share common pass knot identifier.In addition, in the instance of Fig. 2 A, be added one of five computing nodes as a part that changes C7, begin alternative computing node simultaneously corresponding to incident E9b for the substitute node of disabled computing node because variation C6 becomes.Therefore, go 295j (corresponding to incident E9b) with row 285i (corresponding to changing C7) also share identical common pass knot identifier.In other embodiments; If through providing four additional calculations nodes corresponding to incident E4-E6 in incident E9b, to begin to provide alternative computing node individually; For example to replace unavailable computing node immediately; Then the respective change of said alternative computing node will finish to take place before at period 260b and the Coordinating Activity that carries out thus H2, and will in table 280, illustrate individually with the said extra variation of sharing different corresponding pass knot identifiers with incident E9b.In addition; Though five computing nodes that add to changing C7 with the mode of polymerization shown in the single file of table 280; But in other embodiments, each computing node that is added all can represent in the independent row 285 of table 280, and if so; It shares identical pass knot identifier N7 separately, and this pass knot identifier N7 changes the unique capable 285i of C7 to polymerization at present and illustrates.

In addition; In this example; In table 280, followed the trail of variation; These change not only corresponding to based on the on-the-fly modifying of the computing node quantity of dynamic subscriber's instruction and/or user's trigger of being satisfied, and also the accident based on computing node quantity changes (for example, becoming unavailable in other words conj.or perhaps because computing node loses efficacy).This type of variation detects based on monitoring; And be illustrated as the incident (alternative computing node for example is provided) that triggers extra variation; But in other embodiments, can otherwise handle, for example not follow the trail of this type of variation and/or the replacement activity of system start-up is not regarded as incident it.In addition; Though the variation in the table 280 and 290-incident is closed knot information not to can be directly owing to one or more corresponding event (for example; Cause the incident of those variations immediately) variation with can be indirectly (for example owing to one or more corresponding event; For example during Coordinating Activity, condense together and cause the incident of those variations jointly) variation distinguish, but in other embodiments, can follow up this type of information.

As previously mentioned, the attribution of responsibility that the specific program executive capability of computing node group is on-the-fly modified can provide various benefits, comprises to the user relevant with the computing node group explanation that why can change is provided.Also can produce and/or use this type of attribution of responsibility information in response to all kinds of inquiries that receive from user or other source, these inquiries are such as being that indication takes place for the availability that causes one group of one or more computing node specific program executive capability is revised or the request of the reason of other variation and/or about which (repeatedly) program executive capability is revised or (a plurality of) change in availability of other computing node group is caused by the incident of one or more indications request about discerning which (a plurality of) incident.Discuss with reference to Fig. 2 B, the pass knot information shown in the table 280 and 290 provides a kind of mechanism that is used to follow the trail of and provide attribution of responsibility information.For example, among Fig. 2 A with change for 5 computing nodes of the corresponding interpolation of C7, the user possibly wonder and added 5 computing nodes why (for example, particularly according to the user instruction of the incident E4 that adds 3 computing nodes).Through adopting the pass knot information shown in Fig. 2 B, PES or other system can be easy to generate automatically the readable explanation of people.For example, in response to about with user's request of the reason of four computing nodes of the corresponding interpolation of the variation C1 of Fig. 2 A, PES or other system can for example indicate following content: " the incident E01 when changing C01 by time T 1 directly causes.Incident E01 is to begin to provide the request of one group of 8 computing node from user UUU ".This information can produce like this: through adopt among the capable 285a corresponding to the pass knot information 280x that changes C1 with in the Identification Lists 290 corresponding to the capable 295a of incident E1; And with required mode from row 285a and 295a, extract and formatted message (for example, with ask based on the user or the form of previous User Preferences, with based on the form of PES default value etc.).Similarly, in response to about carrying out user instruction E1 to begin to provide user's request of eight computing nodes of this group, PES or other system can for example indicate following content: " the incident E01 during time T 1 directly causes variation C01, C02 and C03.Change C01 for adding 4 computing nodes, it begins when time T 1 and when time T 2, finishes.Change C02 for adding 3 computing nodes, it begins when time T 1 and when time T 3, finishes.Change C03 for adding 1 computing node, it is when time T 1, but end ".As another instance; In response to about with user's request of the reason of five computing nodes of the corresponding interpolation of the variation C7 of Fig. 2 A, PES or other system can for example indicate following content: " changing C07 is caused by the incident E05, E06, E04 and the E09b that occur in during the period T11 to T21 indirectly.Incident E05 is the request based on 4 additional calculations nodes that satisfy situation of trigger TR-1.Incident E06 is the request based on 2 additional calculations nodes that satisfy situation of trigger TR-N.Incident E04 is for providing the request of 3 additional calculations nodes of dynamic instruction based on the user from user UUU.Incident E09b is the request based on 1 alternative computing node of the automatic termination of unavailable computing node in this group ".As to the replenishing or substituting of this type of text string, attribution of responsibility information can also various other forms such as automatic form (for example, with form, chart etc.) and is produced with regular or other predetermined way.Be to be understood that in other embodiments, this type of attribution of responsibility information can various alternate manners produces and uses.

Be to be understood that, only be provided for carrying out schematic purpose about the information of incident shown in Fig. 2 B and variation, and for stored information, the storage of this type of information can be carried out by various alternate manners in other embodiments.In addition; In other embodiments; PES can store the information about various other types of user and computing node group, for example to provide storage about user-defined trigger, about the performance measurement information of monitoring, about the add list of the information of user account etc.

In addition, the previous examples of Fig. 2 A and 2B is provided for carrying out schematic purpose, and other embodiment can be different from these instances in every way.For example; Though in these instances, the program executive capability is measured and revised according to the quantity of computing node, for example its prerequisite is that various available computing nodes (for example are regarded as equivalence; Computational resource with equivalence); But other embodiment can be provided, and wherein various available computing nodes can be have different qualities (for example different processing poweies, amount of ram, platform specification etc.) dissimilar, and/or wherein come the tracing program executive capability with the mode that is different from computing node quantity.In some these type of embodiments; Various requests can comprise the indication of the computing node of one or more particular types; Said computing node is used for being selected to carry out many set of calculated node of the program relevant with described request, and those requests only can realize on the computing node of corresponding specified type.

In addition, at least some embodiments, PES or other system also can carry out the activity as other type of the part of many set of calculated of management node.For example; As previously mentioned; PES or other system can determine from the computing node group, to add or remove computing node in each time, and each time comprises as follows: during the Coordinating Activity that when the polymerization period finishes, carries out (in response at one or more triggers that are satisfied during the said period and/or the user instruction that during the said period, receives); In response to through specifying or confirming and have the user instruction of immediate effect or any time that trigger satisfies situation; In response to the automatic movable of PES or other system for example to replace the computing node and/or the termination of losing efficacy and to remove any time of the forbidden computing node of current operation; Deng.In at least some embodiments, PES or other system also can consider other factors when definite time of confirming that at least some these type of computing node groups revise.For example; (for example will be responsible for using in the situation of given quantity Calculation node the user to the given period; Collected the expense of X computing node in next hour), this type of information can be used for confirming the time about the modification of some type at least of computing node group.If the quantity of computing node was reduced to and is lower than X during PES or the decision of other system will be organized; Then PES or other system can determine in fact computing node quantity is reduced to be lower than X before; Wait when finishing near given period or given period (for example, to the user collect the charges hour finish the time).Similarly; If a set of calculated node (was for example losing efficacy when carrying out new Coordinating Activity; When approaching will the end) through a period of time between the computing node quantity modification polymerization period of request; Then PES or other system can determine the number of nodes of actual node quantity with the offical record of choosing wantonly upgraded; Reflecting said inefficacy, but need not to begin immediately to add alternative computing node-like this, if confirmed that polymerization is revised and can the computing node quantity of this group be reduced one or more computing nodes through the computing node quantity of request during Coordinating Activity; The computing node that then lost efficacy can be used as this category node of a minimizing, and the execution computing node that nonterminal should be organized.

In some embodiments, PES or other system can manage the repeatedly dissimilar modification that the computing node group is carried out simultaneously.As an instance; Can adopt the computing node of single position that the computing node group is managed in current required computing node quantity; But the user can determine to specify for the computing node group yardstick of second type, makes that the required subclass of the appointment of computing node is positioned at the different second places in this group.If so; PES or other system can operate to satisfy the expectation value of second yardstick through variety of way; Variety of way comprises through in the group that any new computing node progressively is added into second place place and from the group of primary importance, progressively remove any existing computing node up to the expectation value that realizes second yardstick, and the existing computing node that perhaps stops immediately in the group at primary importance place substitutes computing node and is added in the group at second place place making.This type of progressively adds and/or any way that removes in the mode that can other place discusses in more detail triggers, and comprises replacing unavailable computing node, revising computing node quantity etc. in response to the trigger of the user instruction of dynamically appointment and/or user's appointment of being satisfied.In addition; Though computing node quantity and position are balanced simultaneously in this example; But can carry out the variation (for example, for example changing into second type from first type) of various other types in a similar fashion according to the dissimilar computing nodes that will have now with computational resource of different correlated measures.In addition; Though carried out the modification of program executive capability in some instances through changing computing node quantity; But in other embodiments; This type of ability revise and can carry out through the program executive capability that changes one or more computing nodes in this group (second computing node that for example, has a correlation computations resource of one or more types more or less through usefulness replace first computing node, through to a node in the computing node of the part that becomes this group can with the amount of one or more computational resources make amendment etc.).

As previously mentioned, PES can provide and use types of functionality in each embodiment, and these functions can provide in every way.For example; In some embodiments; Can comprise a plurality of computing nodes from the program executive capability that PES obtains; Said computing node is used for representative of consumer and comes executive routine, for example through via one or more networks or can between computing machine, transmit a plurality of physical computers of other exchanges data dielectric interconnect of data.In these computing machines at least some can comprise separately in some embodiments carry out a plurality of programs simultaneously enough calculating related resources (for example; The enough internal memory write, non-volatile memories, cpu cycle or other CPU usage tolerance, the network bandwidth, swapace etc.); And at least some in these computing machines can provide a plurality of virtual machine computing nodes separately in some these type of embodiments, and on behalf of different users, said virtual machine computing node can carry out one or more programs separately.In addition, in each embodiment, on behalf of a plurality of users, PES can carry out each class method.For example, this class method of carrying out of representative of consumer can comprise one or more operating systems, application (for example, server and/or other software application), utility routine, routine library etc.In addition; In at least some embodiments; This class method can comprise executable software image, and such as virtual machine image, it can start loadable in other words conj.or perhaps on one or more virtual machine computing nodes; And can comprise operating system software separately, be used for the software of one or more application programs, and/or configuration information etc.

In at least some embodiments, on one group of one or more computing node, carry out one or more programs through PES and can cause in response to the current executed request of carrying out those programs immediately.Perhaps, said initiation can be carried out request based on the program that receives before this, and this request can be scheduled to keep in the future in other words conj.or perhaps carry out to those programs in the current time.Program is carried out request and can be received in every way; For example directly (for example receive from the user; Carry out other GUI that service provides via interactive console or by program); Perhaps the user's executive routine carried out voluntarily from one or more other programs of automatic initiation or other instance receives (for example, carrying out the API that service provides via program, such as the API that uses the network service).Program is carried out request can comprise the various information that are used to cause one or more program implementation; Indication such as other duplicate of executable program or program to be carried out, the program that is provided for carrying out in other words conj.or perhaps through registration before this; With many program examples of treating to carry out simultaneously (for example; Be expressed as the required instance etc. of instance, minimum and the maximum quantity of single requirement); And preference and/or the requirement (for example, resources allocation, the geography that is used to carry out and/or logical place, other program and/or computing node close on execution, time correlation standard etc.) that are used to carry out various other types of one or more programs.
