Brief introduction
Although hardware load balancer can be used for helping prevent computing system (its for providing the access to service or resource Can be described as producer's system) because from the computing system for requesting the access to service or resource (it can be described as Consumer System) It requests and becomes that over-burden, but hardware load balancer can suffer from many disadvantages.For example, hardware load balancer provides list A fault point.In other words, if hardware load balancer breaks down, relevant enterprise system may become visit It asks, because service request may be no longer relayed to producer's system.In addition, hardware load balancer can be the impermeable of valuableness Bright hardware, this makes them be unattractive solution for business system load balance for making.
One solution of the problem related to hardware load balancer is using decentralization load balancer.So And although decentralization load balancer will solve the problems, such as and relevant multiple, the decentralization using hardware load balancer Load balancer is often suboptimum because they and do not have global visual angle to business system and each load balance Device is usually limited to serve the definition subgroup of Consumer System and producer's system.
The present disclosure describes be from multiple consumers to distribute between multiple producer's systems using one group of rental agency The embodiment of the system and process of the service request of system.Rental agency can be monitored and be distributed for producer's system subgroup Access or lease, and in most cases, it is known that whole multiple producer's systems.In addition, coming for each service request It says, single Consumer System can be with several rental agencies and multiple producer's system interactions act in some cases.? In certain embodiments, this group of rental agency can serve as mixed load balancer, because load balance process can be made to be distributed Between one group of hardware based distributed system, wherein it is flat to be performed both by the load for producer's system for each rental agency Weighing apparatus.
Advantageously, in certain embodiments, it is maintained simultaneously about every by dividing producer's system between rental agency At least subset of the information of each producer's system at one rental agency can be realized in the case where no disadvantages mentioned above The advantages of both hardware load balancer and decentralization load balancer.In addition, in certain embodiments, by that will not disappear Expense person's system is assigned to specific rental agency and/or producer's system, is divided into multiple isolated subsystems with by producer's system System is compared, and the passage of load at any time as handled by each of multiple producer's systems can be made more to balance.
In some cases, the system and application program realized in producer's system and/or Consumer System are modified To work with rental agency one.For example, as described further below, Consumer System can be modified to lease and be to the producer The access of system and the status information for maintaining producer's system.
In some embodiments, the system and method for the disclosure can be used for can be with trustship consumer virtual machine and life The one or more overlapping networks realized on one group of calculating main frame top of production person's virtual machine.Advantageously, in certain embodiments, The system and method that the disclosure can be realized in the networked infrastructure of consumer host and producer's host, so that energy It is enough that Rental Procedure occurs in the case where not being related to consumer's virtual machine and/or producer's virtual machine.
When the embodiment for realizing the disclosure in overlapping network, rather than producer's system is divided between rental agency When, producer's virtual machine relevant to each overlapping network can be individually divided between rental agency.In addition, that will produce When the lease of person's virtual machine is to consumer's virtual machine, it is empty that rental agency can choose the consumer for being assigned to and being requested for lease Producer's virtual machine of the quasi- identical overlapping network of machine.

Fig. 2 is illustrated for providing the net of the access to the service by 106 trustship of producer's system for Consumer System 104 The alternate figures of the embodiment of network environment 100.As shown in Fig. 2, each system of network environment 100 can pass through network 202 It communicates with one another.Network 202 may include any kind of wired or wireless network and their combination.For example, network 202 can be with Including local area network (LAN), wide area network (WAN), cellular network, the network based on Ethernet, WiFi network, WiLAN network etc..Separately Outside, in some cases, network 202 may include internet.
As shown in Fig. 2, system shown in Figure 1A can respectively include multiple subsystems, multiple subsystem can with hardware or Software realization.For example, Consumer System 104 may include lease requester 240, block of state 242, link block 244 and money Source requester 246.Lease requester 240 can be configured to request one or more lifes from one or more rental agencies 102 The lease of production person's system 106.In some cases, lease requester 240 can especially request the visit to producer's system 106 It asks.In other cases, lease requester 240 can request the access to service, wherein presence or absence of clear request pair The access of producer's system 106.
Once lease requester 240 obtains the identity of one or more producer's systems 106, link block 244 can be tried Establish and communicate with some or all of the production system 106 that is identified by rental agency 102.It is built with producer's system 106 After vertical connection, resource requestor 246 can request resource or service, the producer of Consumer System 104 from producer's system 106 System is successfully established adjoining.
Block of state 242 can obtain the status information about producer's system 106.The information can then be provided Rental agency 102, in response to requesting the access to producer's system 106 that rental agency 102 is promoted to select from Consumer System 104 Select producer's system 106.The information can be provided to the corresponding states module 228 of rental agency 102.In some cases, Block of state 242 is based on being successfully established and the connection of producer's system 106 or be not successfully established and producer's system 106 The case where connection, which gets off, obtains status information.In other cases, pass through inquiry producer's system 106 and/or corresponding states mould Block 262 (a part that these modules are included as producer's system 106) obtains status information.The status information can wrap It includes about any information for making producer's system 106 connect and/or be serviced by the supply of producer's system 106.For example, status information It may include being related to being successfully established between Consumer System 104 and producer's system 106 communicating or without establishing the letter communicated Breath.As another example, status information may include the Consumer System in given time period access producer's system 106 104 quantity.Other example may include the responsiveness for being related to producer's system 106, the ability of producer's system 106, life The information of available resource etc. at production person's system.
As shown in Fig. 2, producer's system 106 may include registration module 260 and block of state 262.As it was earlier mentioned, shape Morphotype block 262 can be provided to Consumer System 104 is related to the status information of producer's system 106, which is related to The status information of producer's system 106.In addition, in some cases, block of state 262 can be voluntarily or in response to from lease It acts on behalf of 102 request and provides status information to rental agency 102.
Registration module 260 is configured to register producer's system 106 to rental agency 102.In certain embodiments, when When producer's system 106 is started for the first time, registration module 260 can register producer's system 106 automatically, as initialization example A part of journey.In other embodiments, registration module 260 can be in response to the Ordered Registration from user or application program Producer's system 106.In some cases, registration module 260 can determine its lease generation distributed in producer's system 106 Producer's system 106 is registered when managing no longer available.
As previously mentioned, rental agency 102 can also include block of state 228.Block of state 228 can be from Consumer System 104 and producer's system 106 in one or two reception about producer's system 106 state status information.In addition, shape Morphotype block 228 can provide status information relevant to producer's system 106 to another rental agency 102.In addition, some In the case of, block of state 228 can be by executing the strong of other rental agencies 102 from other 102 solicited status of rental agency Health inspection.For example, whether block of state 228 can be determined lease generation by 102 response of rental agency based on health-check request Whether reason 102 is no longer available.In some cases, block of state 228 can be by holding from 106 solicited status of producer's system The health examination of row producer system 106.
Other than block of state 228, rental agency 102 can also include producer's repository 220, dividing system 222, rent System of renting 224 and registration module 226.Producer's repository 220 may include any kind of database, repository or memory It is related to the information of producer's system 106 for storing.For example, producer's repository 220 may include and 106 phase of producer's system The status information of pass, the identity of producer's system 106 and it is related to distribution of the producer's system 106 between rental agency 102 or draws The information divided.In some embodiments, it may replace producer's repository 220 or other than producer's repository 220, will deposit Information some or all of of the storage at producer's repository 220, which is stored in, acts on behalf of repository 206.
Dividing system 222 may include that can divide that producer's system can be used between the rental agency 102 of network environment 100 106 any system.In general, dividing system 222 can be divided into non-overlap or non-equivalent subgroup with producer's system 106 And a subgroup then is distributed for each rental agency 102.Therefore, if there is four rental agencies 102, then producing Person's system 106 can be divided into four subgroups, and wherein each subgroup is related to a rental agency 102.However, in some feelings Under condition, these subgroups can be overlapped.In this case, producer's system 106 can be assigned multiple rental agencies 102 or It is related to multiple rental agencies 102.The process that producer's system 106 is divided between rental agency 102 can be in network environment 100 When being started for the first time.In addition, the process can periodically occur again.For example, whenever available producer's system 106 Quantity variation or can occur to divide the process of producer's system 106 when changes of threshold occurs for available producer's system 106, The mode of producer's system 106 can be used whether through increasing or deleting.
When Consumer System 104 requests to request the access to producer's system 106 from rental agency 102, lease system System 224 can be identified based on Multiple factors for leasing the producer's system 106 for arriving Consumer System 104, these factor packets The position of status information for example relevant to producer's system 106, producer's system 106 is included (for example, in geographical location, data The heart, server rack etc.) and producer's system 106 whether can obtain Consumer System 104 attempt access resource.Once Leasing system 224 identifies that producer's system, leasing system 224 can provide producer's system 106 for requesting consumption person's system 104 Identity.In addition, in some cases, leasing system 224 can be provided for Consumer System 104 Consumer System 104 in order to Access producer's system 106 and authorized lease time.Alternatively, or in addition to this, leasing system 224 can be to disappear Expense person's system 104 provides some a certain amount of other consumable resource or measurement.For example, the consumable resource can be all to calculate Phase, currency, magnetic disk storage connection request etc..
Registration module 226 can serve as the corresponding part of the registration module 260 of producer's system 106.Once from the producer System 106 receives the request registered to rental agency 102, and the registration module 260 of rental agency 102 can determine that the producer is Whether system 106 is assigned to rental agency 102.If it were to be so, then registration module 226 is registrable producer's system 106, this may include store producer's system 106 usability status and with the production in such as producer's repository 220 The relevant status information of person's system 106.On the other hand, if registration module 226 determines that producer's system 106 is not assigned to rent Rent agency 102, then registration module 226 can identify another rental agency 102 for being assigned to producer's system 106 and can To notify the identity for the rental agency 102 for being assigned to producer's system 106 to producer's system 106.
In certain embodiments, network environment 100 may include acting on behalf of repository 206 and/or dividing system 204.Generation Reason repository 206 may include the letter about rental agency 102 and/or producer's system 106 included in network environment 100 Breath.Acting on behalf of the information stored in repository 206 can be by rental agency 102, Consumer System 104 and producer's system 106 In one or more use.For example, in some cases, rental agency 102, which can be used, acts on behalf of the determining network of repository 206 The quantity and/or identity of producer's system 106 of environment 100.By using this information, rental agency 102 can be determined such as What divides producer's system 106.In some cases, Consumer System 104 can be used act on behalf of repository 206 determination producing Person's system 106 by rental agency 102 identify with by Consumer System 104 access after, by the producer's system positioning where.Make To use another example for acting on behalf of repository 206, in some cases, producer's system 106 is accessible to act on behalf of repository, To determine for example when producer's system 106 is started for the first time by the identity of the rental agency of access 102.
In some embodiments, dividing system 204 can be executed for dividing producer's system between rental agency 102 106 process.In such embodiments, rental agency 102 may not include the dividing system 222 of their own.
In some embodiments, can make in system shown in Figure 2 included at least some modules with by these systems The application program and/or resources integration of offer.For example, can make the block of state 262 of producer's system 106 be with by the producer The application program and/or resources integration that system 106 provides.Similarly, block of state 242 can be made and by 104 support of Consumer System The application program or Services Integration of pipe.
For accessing the example flow of the service at producer's system
Fig. 3 illustrates the embodiment of the process 300 for accessing the service at producer's system 106.Process 300 can be by Any system realizes that the system can access lease or the temporary Authorization of producer's system 106 by obtaining from rental agency 102 To access service or the computer resource at producer's system 106.For example, can be by Consumer System 104, lease requester 240, link block 244, resource requestor 246 and block of state 242 (naming just a few) wholly or partly execute process 300.Although any number of system can wholly or partly implementation process 300 will be referring to specific in order to simplify discussion 300 each section of System describe process.
Process 300 starts in block 302, wherein such as lease requester 240 is generated for accessing producer's system 106 Lease request.In some cases, lease request may include the application journey on Consumer System 104 or Consumer System 104 The identity of computer resource or service that the user of sequence desires access to.In other cases, lease request cannot not be included in specifiedly life The request of producer's system 106 will be accessed at production person's system 106 in the case where the service accessed by Consumer System 104.
In block 304, the subgroup of lease requester 240 rental agency 102 included into network environment 100 provides rent It rents request.In some cases, lease requester 240 can be used rental agency 102 to provide lease request to some or all. Lease requester 240 can be identified by access agent repository 206 to use rental agency 102, this may include network rings The identity of each rental agency 102 in border 100.In other cases, Consumer System 104 can initialize or start When, or any other time during Consumer System 104 operates, respectively it is configured to the identity with rental agency 102. For example, user (for example, administrator) can provide the identity of rental agency 102 for Consumer System 104.Rental agency 102 Identification may include the title of rental agency 102, rental agency 102 address (for example, the Internet Protocol address (IP) or other Network address) and/or can be used to identify any other information of the rental agency 102 in network environment 100.In some embodiment party In case, providing lease request to rental agency 102 may include providing for rental agency 102 and one or more producer's systems 106 relevant status informations, Consumer System 104 had previously been acted on these producer's system interactions.
In block 306, Consumer System 104 is each from 102 subgroup of rental agency for providing lease request in block 304 A identification for receiving producer's system 106.In some cases, Consumer System 104 is from 102 subgroup of rental agency certain is some The middle identification for receiving producer's system 106.For example, Consumer System 104 can be from one, two or complete of rental agency 102 The identification of producer's system 106 is received in whole subgroup.Consumer System 104 does not receive any producer's system 106 wherein Identity in the case where, process 300 can terminate, can repeat to block 302 and/or 304 relevant operations, and/or use (for example, administrator) may be warned at family.In some cases, the identification for receiving producer's system 106 includes consumer system System 104 is authorized to or leases the time span of the access to producer's system 106.Subgroup from rental agency 102 Each rental agency 102 can provide the identity of single producer's system 106.However, in some cases, from lease Each of the rental agency 102 of the subgroup of agency can provide the identity of multiple producer's systems 106.With rental agency 102 identity is the same, and the identity of producer's system 106 may include identification producer's system 106 and Consumer System 104 or mention For accessing any information of the method for producer's system 106.For example, the identity of producer's system 106 may include title, address (for example, IP address) or it can be used for being located in producer's system 106 in stored table or data structure (for example, being located in Act on behalf of in repository 206) identifier.
In some cases, block 306 may include receiving the production identified by each of 102 subgroup of rental agency The status information of person's system 106.The status information can be used for that 104 determination of Consumer System is helped to access that producer system System 106.In some cases, status information can be obtained by the rental agency 102 communicated with producer's system 106.It is alternative Ground, or in addition to this, status information can be obtained from the Consumer System 104 previously communicated with production system 106.It is connect The status information of receipts may include be available for rental agency 102 status information be independently arranged or subgroup.In some cases Under, received status information may with may not also be with the status information reciprocation that is available for rental agency 102.
In block 308, link block 244 attempt initialization with it is every in producer's system 106 for being identified at block 306 One connection.In some cases, link block 244 can attempt the producer's system identified in initialization and block 306 The connection of 106 subgroup.Trial initialization connection can include attempt to open any with the communication channel of producer's system 106 Process.For example, attempting initialization connection may include sending connection request packet to producer's system 106.In general, work as consumption When person's system 104 receives the identity of producer's system 106, link block 244 can be attempted to establish the company with producer's system 106 It connects.When Consumer System 104 can be received rarely from multiple rental agencies 102 simultaneously to be responded (for example, because rental agency 102 can be positioned from Consumer System 104 it is different with a distance from or can have a different loads), link block 244 can be rare Ground is attempted while the connection of initialization and multiple producer's systems 106.On the contrary, what initialization was connect with producer's system 106 It attempts staggeredly to carry out, even if in very small degree.However, in some embodiments, link block 244 can taste The connection of examination while initialization and multiple producer's systems 106.For example, in some cases, consumer module 104 can wait It, can be simultaneously from multiple rental agencies until each of 102 subgroup of rental agency makes a response, or in some cases 102 receive response.
In a block 310, resource requestor 246 accesses or requests access to the computer money from first producer's system 106 Source, link block 244 are successfully established with first producer system and connect.In some cases, with 106 success of producer's system Establishing connection may include that confirmation (" ack ") packet etc. is received from producer's system 106.In order to above in regard to described in block 308 Similar reason can establish connection with producer's system 106 in a staggered manner.However, link block 244 is not wherein Have in the case where substantially simultaneously establishing connection simultaneously with more than one producer's system 106, resource requestor 246 can be random Producer's system 106 is selected, is accessed and is serviced by producer's system request.Alternatively, choosing can be used in resource requestor 246 Service will be requested with determination from which producer's system 106 by selecting algorithm.The selection algorithm be not limited and including such as poll, The selection algorithm of least recently used (LRU) or any other type.In some embodiments, Consumer System 104 can be with Request access to from some or all of service of producer's system 106, have been established with the communication connection of these producer's systems or Communication channel.In some cases, which can have same type.In other cases, Consumer System 104 can request By the access of 106 pairs of each producer's system different services.
In addition, successfully being built wherein compared with Consumer System 104 is needed for particular point in time with more producer's systems In the case where vertical connection, Consumer System 104 can surrender of lease one or more additional producer's systems 106.Alternatively, Consumer System 104 can be such that the lease to additional producer's system 106 is maintained in lease pond and can maintain to additional The connection of producer's system 106.In this case, if in some of the leasing period to additional producer's system 106 Between, Consumer System 104 requests access to Additional Services, then Consumer System 104 can use in additional producer's system 106 One service, leases of these additional producer's systems 106 are maintained in lease pond.
In block 312, block of state 242 connects 106 reception state metadata of producer's system from first.In some cases Under, block of state 242 can be from each 106 reception state metadata of producer's system, link block 244 and the producer System is successfully established communication channel.In addition, block of state 242 can obtain state metadata, link block from producer's system 106 244 fail to establish communication channel with the communication module.Lead to for example, link block 244 fails to establish with specific manufacturer system 106 The fact that believe channel can be included as state metadata relevant to producer's system 106.The state metadata not by It limits and may include: the information for being related to establishing connection with producer's system 106；It is related to maintaining to connect with producer's system 106 Information；It is related to the information of the responsiveness of producer's system 106；And it is related to the information of available service at producer's system 106. For example, state metadata may include: elapsed time amount in the process for be connected to producer's system 106；It is connected to production Delay in the process of person's system 106；Available processes resource at producer's system 106；Request must be resend to life The number (for example, caused by because of packet loss) of production system 106；And it can be relevant to the state of producer's system 106 any other The data of type.
In some embodiments, block 312 can execute before block 310.In this case, block of state 242 It can be from each 106 receiving status information of producer's system connected.In this case, Consumer System 104 can With based on received status information come select access service producer's system 106.
In decision block 314, the Consumer System 104 of such as resource requestor 246 is used to determine the need for accessing Another service.Another service can make different services, or can also make same type of service.For example, one In a little situations, a service can be used for accessing web application, another service can be used for down loading network resource (for example, By the image or video of Webpage such as webpage trustship).Alternatively, the two services may be used to download network money Source.For example, user can download two Webpages or resource from two Webpages.If it were to be so, so connecting The connection of the producer's system 106 identified in the initialization of module 244 and block 308.In some cases, at the beginning of link block 244 The connection of beginningization and the producer's system 106 relevant with Consumer System 244 identified in lease pond.Lease pond can wrap It includes and has currently been leased for being used for Consumer System 104 providing the identity of producer's system 106 of the access to resource.Some In the case of, lease pond includes being leased for producer's system 106 of Consumer System 104, rather than Consumer System 104 is current Those of do not access.If leasing pond does not include any lease, Consumer System 104 can be asked for example in operating lease Device 240 is sought to execute process 300 again.In some embodiments, decision block 314 is optional.For example, if not producing Person's system 106 is leased for Consumer System 104, then process 300 can start to repeat with block 302.
In some embodiments, process 300 can be used for updating the previous lease to producer's system 106.At this In the case where sample, lease request may include the previously visited producer's system of Consumer System 104 generated in block 302 106 identity.In addition, it is to update to request this instruction that lease request, which may include request,.It can then be mentioned to rental agency 102 It is requested for more fresh tenancy, more fresh tenancy request is originally identified producer's system 106 and Consumer System 104.Assuming that lease generation Reason 102 determines that producer's system 106 is still available and/or has the ability to 104 offer service of Consumer System, then rental agency 102 may indicate that updating request has been given the ratification and can provide the time span of more fresh tenancy to Consumer System 104, makees For a part of block 306.The lease to one or more additional producer's systems 106 is kept in wherein Consumer System 104 It is not using the additional producer in lease pond and to the leasing period of additional producer's system 106 in Consumer System 104 Unite service at 106 when failure in the case where, Consumer System 104 can permit leasing period failure, without to additional life The corresponding rental agency 102 of production person's system 106 sends lease and updates request.
In some cases, request the process updated can be leased when existing lease expires.In other cases, it uses The Consumer System 104 of such as resource requestor 246 can be determined for accessing at one or more producer's systems 106 A possibility that existing service request of service will not be completed before lease time expires.If the possibility, which meets, updates threshold Value, then Consumer System 104 can request to update producer's system 106 at some time point before existing lease expires Thus lease reduces or prevents service disruption caused by expiring due to lease.
In certain embodiments, lease to the access of producer's system 106 may include to producer's system 106 And/or the relevant tissue of one or more or entity of rental agency 102 provide payment.For example, producer's system can be made 106 can be used as a part of pay-for-access service.Alternatively, lease may not be needed to appoint to the access of producer's system 106 The payment of which kind of class.In such embodiments, lease refer to the access to producer's system 106 occasional nature and It is not financial lease.
For providing the example flow of the lease to producer's system for Consumer System
Fig. 4 illustrates the implementation of the process 400 for providing the lease to producer's system 106 for Consumer System 104 Scheme.It can be by that can be any system for the identity that Consumer System 104 provides producer's system 106 come implementation process 400.Separately It outside, can be by that can be any system implementation process 400 of the lease of Consumer System 104 to the access of producer's system 106.Example It such as, can be by rental agency 102, leasing system 224 and block of state 228 (naming just a few) wholly or partly implementation process 400.Although any number of system can wholly or partly implementation process 400 will be referring to specific in order to simplify discussion 400 each section of System describe process.
Process 400 is with the beginning of block 402, in block 402, for example, the leasing system 224 of rental agency 102 is from consumer System 104 receives the request of access of the lease to producer's system 106.In some cases, which may include consumer system System 104 attempts the special services of access or the identity of computing resource at producer's system 106.As described in previous section, some In the case of, lease request may include the request that existing lease is updated by the consumer 104 of producer's system 106.
In block 404, block of state 228 can receive one or more producer's systems 106 from Consumer System 104 State metadata.This received state metadata of institute may include previously having attempted and one or more with Consumer System 104 The relevant data of service of the communication of producer's system 106 or access from one or more producer's systems 106.For example, being connect The state metadata of receipts may include delay information, be related to responsiveness of the request to producer's system 106 of Consumer System 104 Data or previously in relation to any other information described in block 312.In addition, the received state metadata of institute may include consumption The friendship based on itself and producer's system 106 from the received data of producer's system 106 and/or Consumer System 104 of person's system 104 Interaction is used as the data mode metadata of generation.In some embodiments, block 404 can be optional.For example, if this is asked Seeking Truth is requested from Consumer System 104 received first, then Consumer System 104, which may and not have, will be supplied to lease Any state metadata of agency 102.
In block 406, block of state 228 based in block 404 institute received state metadata update producer's system Status information.In some cases, update producer's system status information may include update producer's database 220 in life The relevant entry of production person's system 106.In some embodiments, block 406 can be optional.
In addition, the institute in block 404 is received at least some to the offer of the second rental agency for block of state 228 in block 408 State metadata.For example, execute process 400 rental agency 102 can determine in the state metadata it is some for point It is fitted on producer's system 106 of another rental agency 102.In such a scenario, rental agency 102 can be to being assigned to The rental agency 102 of producer's system 106 provides status information.In other cases, rental agency 102 can be to rental agency The 102 all rental agencies 102 just communicated with provide state metadata, these rental agencies can be network environment 100 Some or all of rental agency 102.Can be realized in network environment 100 transmission of any kind of data, duplication and/or Synchronous process, to share state metadata between rental agency 102.For example, injection filling algorithm or prim algorithm can be used In in 102 data sharing of rental agency.Description can be herein in 102 data sharing of rental agency in the following terms Spare system and method: on December 28th, 2010 submit and entitled " DATA REPLICATION FRAMEWORK " beauty State applies for No.12/980,133；It submits on December 28th, 2010 and entitled " DATA REPLICATION FRAMEWORK " U. S. application No.12/980,153；On December 28th, 2010 submits and entitled " DATA REPLICATION The U. S. application No.12/980,193 of FRAMEWORK "；With submission on December 28th, 2010 and entitled " DATA The U. S. application No.12/980,258 of REPLICATION FRAMEWORK ".Each in these above-mentioned applications is accordingly with reference Mode be incorporated in its entirety.
In some embodiments, block 408 is optional.For example, in some embodiments, Consumer System 104 is only Status data is provided to rental agency 102 and is used for producer's system 106, these producer's systems are assigned to be connect in block 402 Receive the rental agency 102 of request.
In block 410, leasing system 224 based on each producer's system for assigning or being assigned to rental agency 102 106 relevant status informations select producer's system.In some cases, producer's status information is based on being by consumer The information that system 104 provides (for example, the received state metadata of institute in block 404).In other cases, producer's status information It can be based on the information obtained by the rental agency 102 communicated with producer's system 106.For example, rental agency 102 can be held Row is assigned to the health or status checkout of each producer's system 106 of rental agency 102.These health examination may include Table tennis request is issued to producer's system 106, the update of Resource Availability is requested from producer's system 106 or is related to giving birth to for obtaining The information of the state of production person's system 106.It is based on being received from other rental agencies 102 in addition, producer's status information can be Information.
In certain embodiments, selection producer's system 106, which can be, is at least partially based on and different producer's systems 106 relevant weights.These weights can be generated based on producer's status information.For example, producer's status information, shows Producer's system 106 has low latency and low error rate when communicating with Consumer System 104, can lead to producer's system 106 weights are higher and therefore more likely selected in block 410.On the contrary, producer's system 106, usually breaks and disappears The connection of the person's of expense system 104, possible weight is lower and is therefore less likely to be selected in block 410.
In some cases, the selection of producer's system 106 can be based on any number of additive factor, such as produce Position of the person's system 106 about Consumer System 104.Location information may include whether such as producer's system 106 is positioned In data center identical with Consumer System 104 or identical server rack.In some cases, selection producer system System 106 can be based on by the requested service of Consumer System 104.In other cases, the selection of producer's system 106 can To be to be at least partially based on the lease time for requesting and/or being previously allocated to Consumer System 104 by Consumer System 104 Amount.In some cases, leasing system 224 can choose the smallest producer's system 106 of load.In other cases, it leases System 224 can select producer's system 106 in one group of producer's system 106 from load lower than threshold value.In some embodiment party In case, the load of selected producer's system 106 be determined to be once selection i.e. increase, but regardless of Consumer System 104 whether Connection is established with selected producer's system 106.Advantageously, in certain embodiments, by recording selected production The increased load of person's system 106, irrespective of whether the system for having connected consumer Yu producer's system, same producer's system 106 a possibility that being selected over threshold number within a certain period of time reduction, because while the actual negative of producer's system 106 Carrying may be lower, but the following connector for being directed to Consumer System 104 can be considered in the process of selection producer's system Anticipated load.
In some cases, it may include that selection is negative relative to one or more that producer's system 106 is selected in block 410 Carry producer's system 106 (for example, connection, processor utilization etc.) that measurement has minimum load.Alternatively, selection production Person's system 106 may include selection load lower than producer's system 106 between one group of producer's system 106 of threshold load.From Load lower than load threshold this group of producer's system 106 between selection producer's system 106 can be it is random, pseudorandom or (for example, least recently used, intermediate loads etc.) based on selection algorithm.Advantageously, in some embodiments, by from one Producer's system 106 is selected in group producer's system 106 rather than selects to load minimum producer's system 106, load always A possibility that swing and/or incidence reduce.In addition, loading foam or load heat compared with the remainder of network environment 100 The incidence of the incidence system subgroup such as relevant to the high load for travelling across network environment 100 of point reduces.
In block 412, leasing system 224 is provided to Consumer System 104 is about the producer selected in block 410 The information of lease of system 106.This information of lease may include the identity of producer's system 106, and in some cases, consumption Person's system 104 is authorized to the lease time amount of producer's system 106.As it was earlier mentioned, the identity of producer's system 106 can To include any information such as network address that can contribute to position and access producer's system 106.In some embodiments In, the identity for providing producer's system 106 may include providing voucher or public-key cryptography, in order to logical with producer's system 106 Letter.
As indicated previously, in some cases, process 400 can be used for leasing update request.In this case, block Whether 410 producer's systems 106 that can include determining that Consumer System 104 has requested that lease updates still can be used for leasing.Really Determine producer's system 106 whether still can be used for lease can include determining that producer's system 106 whether have continue service consumption The resource capability of person's system 104.In addition, determining whether producer's system 106 still can be used for leasing can include determining that and produce Whether one or more measurements of the relevant producer's status information of person's system 106 meet availability threshold value.For example, the determination can To include checking whether error rate relevant to producer's system 106 is lower than threshold error rate.If producer's system 106 can be used It is updated in lease, then rental agency 102 can send the lease of the update to producer's system 106 for Consumer System 104. If rental agency 102 determines that producer's system 106 is not useable for lease and updates, rental agency 102 can be reported like this And/or it provides to the information of lease for substituting producer's system 106.
Example producer's system update process
Fig. 5 illustrates the embodiment of producer's system update process 500.It can be by producer's system 106 may be updated Availability and can between rental agency 102 subdivided producer's system 106 any system implementation process 500.For example, can be with It is whole by rental agency 102, dividing system 222, dividing system 204, registration module 226 and block of state 228 (naming just a few) Ground or partly implementation process 500.Although any number of system can wholly or partly implementation process 500, in order to Simplify and discusses, it will be referring to specific 500 each section of System describe process.
Process 500 starts in decision block 502, in block 502, for example, the block of state 228 of rental agency 102 determines Whether state is received from producer's system 106 to update.It can be by rental agency 102 in response to being sent by rental agency 102 Request to producer's system 106 carrys out predicted state update.Alternatively, block of state 228 can predict due to the producer State caused by the relevant update module of system 106 updates.For example, in some cases, each producer's system 106 is equal It can be configured to issue table tennis request to the rental agency 102 distributed every hour or daily or provide state more to the rental agency Newly.If receiving status information, process 500 waits next state to update back to decision-making module 502.In addition, Block of state 228 can update producer's repository 220 and/or act on behalf of life relevant to producer's system 106 in repository 206 Production person's status information.
On the other hand, if being not received by state update, the more new production of block of state 228 in decision block 502 The state of person's system 106, to show the unavailability of producer's system 106 in block 504.Update the shape of producer's system 106 State may include producer's repository 220 and/or act on behalf of in repository 206 store producer's system 106 be not useable for leasing To the instruction of Consumer System 104.In some cases, even if receive state update in decision block 502, block of state 228 can also update the state of producer's system to show that producer's system 106 is unavailable in block 504.For example, if being connect It is more than that threshold value is missed that the bright producer's system 106 of the status information table of receipts, which is just out of order, is just generated with threshold value rate for request service or just, The error of rate, then block of state 228 can update producer's repository 220 and/or act on behalf of repository 206 to show to produce Person's system 106 is no longer available.In some embodiments, the status information of producer's system 106 is updated to show its availability Loss may include that alert management person producer system 106 is no longer available.Update producer's system 106 status information relative to Figure 10 more detailed description.
In decision block 506, whether producer's system 106 of 222 threshold value amount of dividing system is become unavailable.If No, then process 500 waits next state to update back to decision-making module 502.If dividing system 222 is in decision block 506 Producer's system 106 of middle threshold value amount becomes unavailable, then dividing system 222 executes producer's system in block 508 Subdivided process.This subdivided process of producer's system is described in further detail below in relation to Fig. 6.In some embodiment party In case, one or two in decision block 506 and block 508 is executed by dividing system 204.
Example division process
Fig. 6 illustrates the embodiment of the division process 600 for dividing one group of producer's system 106.It can be by that can chase after Track can with the variation of the quantity of producer's system 106 and can between rental agency 102 subdivided producer's system 106 any system System implementation process 600.For example, can be by rental agency 102, dividing system 222, dividing system 204, registration module 226 and shape Morphotype block 228 (naming just a few) wholly or partly implementation process 600.Although any number of system can integrally or portion Divide ground implementation process 600, but is discussed to simplify, it will be referring to specific 600 each section of System describe process.
Process 600 starts in block 602, in block 602, for example, the tracking of block of state 228 can use producer's system 106 Increment.In some cases, the tracking of block of state 228 can use the absolute change of the quantity of producer's system 106.It is alternative Ground, or in addition to this, the tracking of block of state 228 can use the change rate of the quantity of producer's system 106.Producer's system can be used 106 increment or variation can be the addition based on new producer's system 106 or the loss of availability of producer's system 106. In some embodiments, process 500 can be used for identifying the loss of availability of producer's system 106.In addition, the producer can be used The determination of system 106 can be based on user's update, this shows the loss or addition of producer's system 106.Furthermore, it is possible to base It is attempted in the registration of producer's system 106 to track the addition of producer's system 106.It in some cases, can be based on by disappearing Information provided by expense person's system 104 determines the availability of producer's system 106.Furthermore it is possible to regard to producer's system 106 Tracked for actual quantity or for the variation of the percentage of the availability of producer's system 106 can with the increment of the producer or Variation.
In some embodiments, producer's system 106 is tracked by each rental agency 102 and/or the producer can be used The increment of system 106.Alternatively, the available producer system of rental agency 102 is distributed in the tracking of each rental agency 102 System.In addition, or alternatively, by the autonomous system such as tracking of dividing system 204 can with the counting of producer's system 106 and/or Increment.
In decision block 604, whether 222 determination of dividing system can meet threshold value with the increment of producer's system 106.This Increment can be absolute value.In other words, the addition or reduction of producer's system 106 can be tracked.It in certain embodiments, can be with The addition or reduction of producer's system 106 are independently tracked using independent threshold value relevant to each producer's system 106. Therefore, in some cases, even if with total change cancellation of producer's system or can be unsatisfactory for combining threshold value, it also can satisfy one A or two threshold values.In some cases, increment can indicate percentage variation and/or change rate.In this case, threshold Value can be percentage threshold and/or Threshold variety.
If increment is unsatisfactory for threshold value, or if increment is all unsatisfactory for corresponding threshold value, block of state 228 is in block 602 In continue tracking can be with producer's system 106, or the variation of producer's system 106 can be used.On the other hand, in block 606, if Increment meets threshold value or increment meets corresponding threshold value, then dividing system 222 notifies to execute process to other rental agencies 102 The division or subdivided process of 600 rental agency 102 just initialization producer's system 106.Advantageously, in certain embodiments In, by notifying the rental agency 102 for executing process 600 just initialization to divide process, process 600 to other rental agencies 102 It avoids that multiple rental agencies 102 is made to be performed simultaneously division process, this may result in the counting due to such as producer's system 106 Non-optimal result is generated with the race condition in division.In some embodiments, block 606 can be optional.For example, In some embodiments, the dividing system 204 isolated with rental agency 102 can execute division or subdivided process.
In block 608, dividing system 222 obtains the identity that can use producer's system 106.Dividing system 222 can pass through It accesses producer's repository 220 and/or obtains the identity that can use producer's system 106 by access agent repository 206.? Under some cases, dividing system 222 can obtain the body that can use producer's system 106 by contacting other rental agencies 102 Part.
In block 610, dividing system 222 divides between rental agency 102 can use producer's system 106.Dividing system 222 Any kind of partitioning algorithm can be used to divide producer's system 106.In general, producer's system 106 is in lease generation Division between reason 102 generates the non-overlap or non-equivalent combination that can be assigned to producer's system 106 of rental agency 102.However, In some cases, dividing can be overlapping.In addition, in some cases, these subgroups can be unbalanced.Change speech It, some rental agencies 102 can be assigned more producer's systems 106 compared with other rental agencies 102.Wherein this In a little group of unbalanced situation, the quantity or percentage for distributing to producer's system 106 of specific rental agency 102 be can be It is at least partially based on rental agency 102 and/or distributes to the manageable request of producer's system 106 of rental agency 102 Quantity.For example, if the first rental agency 102 be assigned compared with other producer's systems 106 be capable of handling it is greater amount of Producer's system 106 of Consumer System 104, then first rental agency can be assigned and another 102 phase of rental agency Fewer producer's system.
In addition, the implementation of the service different from other producer's systems can be provided in wherein some producer's systems 106 In scheme, producer's system 106 be can be divided into so that each rental agency, which is assigned, can provide special services Producer's system.Alternatively, can divide between the selected subgroup of rental agency 102 can provide the production of special services Person's system 106.
In block 612, once block 610 is completed, the dividing system 222 for executing the rental agency 102 of process 600, which utilizes, to be divided The identity of producer's system 106 of each of rental agency 102 is fitted on to update other lease generations in network environment 100 Each of reason 102.In some embodiments, block 612 may include being assigned to its own using producer's system 106 Identity executes the rental agency 102 of process 600 to update.Updating rental agency 102 using the identity of producer's system 106 can be with Including updating table or database in producer's repository 220.In some cases, since rental agency 102 just executes process 600, then block 612 relative to rental agency 102 is optional and only with respect to other rent included by network environment 100 The agency 102 that rents executes.
In some embodiments, it is first between rental agency 102 to may be used to provide producer's system 106 for process 600 Begin to divide.For example, when network environment 100 is configured for the first time decision block can be able to satisfy with the increment of producer's system 106 604 threshold value, because available producer's system 106 is activated.Alternatively, or in addition to this, user can be in network environment Start when being configured for the first time or in any other time and divides process.
Process 600 is described as to divide producer's system 106 between rental agency 102.However, process 600 and unlimited In this.In some cases, process 600 can be used for dividing lease between rental agency 102, these leases, which are provided to, to disappear Expense person's system 104 is for accessing producer's system 106.For example, rental agency 102 or dividing system 222 can identify one group can With producer's system and determine that can be used for the group can use multiple leases of each producer's system of producer's system.It executes The rental agency 102 of process 600 can be can be also possible to for detecting with the first rental agency 102 of the changes of threshold of lease It is exclusively used in executing the rental agency 102 that lease divides.Rental agency 102 can be based on the institute from each producer's system 106 Received status information can use the quantity (for example, during registration of producer's system 106) of lease to identify.Alternatively, Or in addition to this, can type based on producer's system 106 or based on the configuration information received from producer's system 106 or User (for example, administrator) can use the quantity of lease to determine.
Rental agency 102 can be by each rental agency 102 of access from multiple rental agencies 102 come multiple The multiple leases that can be used for each producer's system 106 are divided between rental agency 102, the lease subgroup from multiple leases can For each producer's system 106.Multiple leases coequally or substantially can be coequally divided between rental agency 102.? Under some cases, since lease quantity is not the multiple of the quantity of rental agency 102, in rental agency 102 at least It is some to be assigned one or more leases.In addition, in some cases, lease may be due to for example certain rental agencies Configuration variance between 102 and/or certain producer's systems 106 is without evenly dividing.In some cases, each is leased Agency 102 is assigned non-overlap lease combination.Alternatively, at least some of these leases can be assigned to multiple leases Agency 102.In some embodiments, multiple rental agencies 102 that lease is divided into producer's system 106 just be can be into rent Rent agency 102 subgroup.Such as, in some cases it may the subgroup of rental agency 102 is assigned to producer's system 106 Subgroup.
After dividing multiple leases or when dividing multiple leases, each of multiple rental agencies 102 are leased For agency 102, the rental agency 102 for executing process 600 can provide for rental agency 102 is assigned to rental agency 102 Lease subgroup.There is provided lease to each of rental agency 102 may include by multiple leases from being assigned to each rent Each producer's system 106 of agency 102 of renting each of is provided to rental agency 102.Alternatively, or except this it Outside, providing lease to each of rental agency 102 may include providing the identity of each distributed lease to rent Rent agency 102.Additionally, it is provided lease may include providing link information, for communicating and/or using with producer's system 106 In the lease using producer's system 106.
Advantageously, in some embodiments, dividing between multiple rental agencies 102 can be used for each producer's system 106 multiple leases realize balance of the workload between multiple rental agencies 102.In some cases, it is not necessary to, The rental agency 102 for executing process 600 provides the lease subgroup for being assigned to its own when executing process 600 for its own.So And in some cases, rental agency 102 can provide lease for its own.For example, in the rental agency for wherein executing division 102 subsystem (for example, dividing system 222) from receive and/or the tracking feelings that be assigned to the subsystem of rental agency 102 different Under condition, the rental agency 102 for executing process 600 can be supplied to the identity of its distributed lease for its own.
In some cases, process 600 can be used between rental agency 102 divide producer's system 106 and with production The relevant lease of each of person's system 106.
Example producer's system registry process
Fig. 7 illustrates the embodiment party that producer's system registry process 700 is used for from the perspective of producer's system 106 Case.Can from can to rental agency 102 register producer's system 106 any system implementation process 700.For example, can be by giving birth to Production person's system 106, registration module 260 and block of state 262 (naming just a few) wholly or partly implementation process 700.Although Any number of system can wholly or partly implementation process 700, but discussed to simplify, will be referring to specific System describe 700 each section of process.
Whenever producer's system 106 is started or is initialized for the first time, or the weight after such as resting stage or system reboot Newly start or reinitialize, process 700 can occur.In some cases, whenever producer's system 106 determines that it is distributed Rental agency 102 it is no longer available, can occur or occur again process 700.Distributed rental agency 102 it is no longer available this Determining can be based on for example from the received information of user institute, from acting on behalf of the received information of 206 institute of repository or in the producer Whether the update of 106 offer state of system receives after such as updating relative to state described in Fig. 5 from the rental agency 102 distributed To ACK.
Process 700 starts in block 702, wherein such as access of registration module 260 is from for example acting on behalf of the one of repository 206 The identity of group rental agency 102.In some cases, the accessible group from internal storage of producer's system 106 is rented Rent agency 102 identity.For example, producer's system 106 can be preconfigured the identity to have one group of rental agency 102. In other cases, user may specify to the rental agency 102 of access.
In block 704, rental agency is selected in this group of rental agency 102 that registration module 260 is identified from block 702 102.Registration module 260 can be randomly or by using any other selection method such as poll or least recently used method To select rental agency 102.In wherein this group of stored situation of rental agency 102, registration module 260 can be in sorting group The first rental agency 102 of middle selection.In certain embodiments, block 704 can be optional.For example, user is specified wherein In the case where rental agency 102, block 704 is unnecessary.
In block 706, the initialization of registration module 260 or trial are initialized and the rental agency 102 selected in block 704 Connection.In some cases, attempting initialization and the connection of rental agency 102 includes the trial registered to rental agency 102.
In block 708, registration module 260 receives connection response from rental agency 102.In decision block 710, registration module 260 determine whether connection response confirms the registration of producer's system 106 or indicate the identity of the second rental agency 102.If In decision block 710, registration module 260 determines that connection response confirms the registration of producer's system 106, then in block 712, state Module 262 is related to the status information of producer's system 106 to the offer of rental agency 102.The status information may include and one Or the relevant any information of state or state of multiple measurements, one or more measurement are related to producer's system 106.Example Such as, status information may include one or more computing resources (for example, memory, processor, network bandwidth, application program etc.) Availability；The quantity for the Consumer System 104 that its service request is just being handled by producer's system；And with producer's system 106 The relevant any other information of state.
Once registration module 260 determines that connection response confirms the registration of producer's system 106, can occur and block 712 Relevant process.Alternatively, or in addition to this, process relevant to block 712 can occur in some later time.In addition, In some embodiments, process relevant to block 712 can continuously occur, and intermittently occur, or can be in response to coming from Rental agency 102 for update producer's system 106 state request and occur.In other embodiments, Mei Dangsheng When changes of threshold occurs for the state or state of production person's system 106, process relevant to block 712 can occur.For example, when being used to give birth to When the availability of the process resource of production person's system 106 drops to threshold level, process relevant to block 712 can occur.
If registration module 260 determines that the received connection response of institute includes the second rent in block 708 in decision block 710 It rents the identification of agency, then in block 714, the connection of registration module 260 initialization and the second rental agency.Such as relative to process Described in 800, the second rental agency may include that the first rental agency (for example, the rental agency identified in block 704) determines For rental agency relevant to producer's system 106.
In block 716, block of state 262 provides status information to the second rental agency.In certain embodiments, block 716 may include the one or more previously in relation to embodiment described in block 712.In certain embodiments, in block 708 Middle received connection response show producer's system 106 be registered in the case where any additional rental agency of nonrecognition whether Success.In this case, if the registration of producer's system 106 is unsuccessful, producer's system 106 can try to infuse The connection of volume or initialization and another rental agency in these rental agencies identified in block 702, and it is opposite It can be with repeatable block 704,706,708 and 710, until rental agency 102 confirms the registration of producer's system 106.
In some embodiments, the second rental agency identified in decision block 710 is randomly selected and/or simultaneously It is not necessarily related to producer's system 106.In this case, block 714 may include executing above in regard to 708 He of block One or more embodiments described in 710, but it is related to the second rental agency.In other words, it can be formed from block 714 to block 708 circuit.In this case, decision block 710 can identify that third is rented in the connection response from the second rental agency It rents and acts on behalf of rather than identify third rental agency in the case where the registration of confirmation producer's system 106.The circuit can be continuously Repeat, until producer's system 106 is successfully registered to rental agency 102.Alternatively, which can execute threshold value Number.If threshold value is met in the case where producer's system 106 does not have successful registration, warning can be generated.Example Such as, (for example, by Email or Alert Popups) producer's system 106 can be notified to fail to be registered to lease to administrator Agency 102.(such as unexpected system failure) in some cases, producer's system 106 may fail to one group of lease 102 registration of agency or the registration for updating them.In this case, the height of the accessible link information of Consumer System 104 Speed caching is leased to try to access producer's system 106.Alternatively, in certain embodiments, by using may arrive The downtime of the cache information of phase, resource access is likely to reduced or eliminates in some cases.
Example producer's system registry process
Fig. 8 illustrates the embodiment that producer's system registry process 800 is used for from the perspective of rental agency 102. Can by can rental agency 102 register producer's system 106 any system implementation process 800.For example, can be by leasing Act on behalf of 102, registration module 226 and block of state 228 (naming just a few) wholly or partly implementation process 800.Although any The system of quantity can wholly or partly implementation process 800, but discussed to simplify, will be referring to specific System describe process 800 each sections.
Process 800 starts in block 802, wherein such as registration module 226 receives registration request from producer's system 106. In some embodiments, which may include voucher relevant to producer's system 106 or encryption key.Register mould Block 226 determines whether producer's system 106 is assigned to rental agency 102 in decision block 804.Determine producer's system 106 Whether being assigned to rental agency 102 may include access producer's repository 220 and/or acts on behalf of repository 206 to determine life Whether production person's system 106 is assigned to rental agency 102.In addition, in some cases, determine producer's system 106 whether by Be assigned to rental agency 102 may include for example based on the received identifier relevant to producer's system 106 of institute, voucher or plus Key changes the identity of producer's system 106.
If registration module 226 determines that producer's system 106 is assigned to rental agency 102, registration module 226 exists The registration of producer's system 106 is confirmed in block 806.The registration for confirming producer's system 106 may include to producer's system 106 It is notified to be registered to rental agency 102.In addition, in some cases, block 806 may include updating producer's repository 220 And/or act on behalf of repository 206 with show producer's system 106 can with and be registered to rental agency 102.In addition, one In a little embodiments, block 806 can also include being provided for producer's system 106 to related to rental agency 102 and/or be assigned to The access of the voucher and/or encryption key of producer's system 106.The voucher and/or encryption key can be used for producer's system Further communication between 106 and rental agency 102.In addition, voucher and/or encryption key can be also used for producer's system Communication between 106 and Consumer System 104, such as to verify the identity of producer's system 106, or protection in the two systems Between the data transmitted.
In block 808, block of state 228 is from 106 receiving status information of producer's system.This status information may include Some or all embodiments described in status information above in regard to block 712.Block of state 228 in block 810 can be with The status information that receives in block 808 is based at least partially on to update the status information for producer's system 106.It is more newborn Production person's status information may include the entry or one or more for updating producer's repository 220 and/or acting on behalf of in repository 206 Measurement, to reflect the state of producer's system 106.
If registration module 226 determines that producer's system 106 is not assigned to rental agency 102 in block 804, then In block 812, registration module 226 identifies another assigned rental agency of producer's system 106.In block 814, mould is registered Block 226 can provide the identity of the assigned rental agency 102 of producer's system 106 to producer's system 106, so that the producer System 106 can contact the rental agency 102 identified in 812.In certain embodiments, block 812 and block 814 can be Optional.For example, in some cases, registration module 226 can be notified to producer's system 106 it not with rental agency 102 Correlation, and the registration request that is therefore received in 802 be it is unsuccessful, without notifying to produce to producer's system 106 The assigned substitution rental agency 102 of person's system 106.
The subdivided process of rental agency
Fig. 9 illustrates the embodiment for the subdivided process 900 of rental agency.It can be by rental agency can will be assigned to Any system implementation process 900 that 102 one group of producer's system 106 is reallocated.For example, can be by rental agency 102, division System 222 and dividing system 204 (naming just a few) wholly or partly implementation process 900.Although any number of system can With wholly or partly implementation process 900, but discussed to simplify, it will be referring to specific 900 each section of System describe process.
Process 900 starts in block 902, wherein dividing system 222 for example relevant to the first rental agency 102 receives separately One or the no longer available instruction of the second rental agency 102.The second rent can be determined based on such as table tennis request or status checkout It rents and acts on behalf of 102 no longer available instructions.In other cases, dividing system 222 can be determined when message does not obtain the second rent When the agency 102 that rents confirms, rental agency 102 is no longer available.In other embodiments, user can specify the second rental agency It is no longer available.In some cases, process 900 can be executed by dividing system 204.
In block 904, dividing system 222 identifies the producer's system 106 for being assigned to no longer available rental agency 102. By access producer's repository 220 and/or it can act on behalf of repository 206 and identify producer's system 106.In block 906, draw Subsystem 222 is divided in the producer's system 106 identified in 904 between remaining rental agency 102.In some cases, block 906 may include notifying that dividing process is occurring, and thus prevents for example previous phase of multiple rental agencies to remaining rental agency 102 For identified producer's system 106 is divided described in block 610 simultaneously.
In some embodiments, block 906 may include subdivided all available producer's systems 106 rather than only divide It is fitted on producer's system 106 of no longer available rental agency 102.In such embodiments, block 904 may include identification All available producer's systems 106.As it was earlier mentioned, the division of producer's system 106 can be overlapping, non-overlap, etc. It is effect, non-equivalent, and/or can be based on producer's type.Therefore, in some embodiments, block 906 may include Previously in relation to some or all of embodiment described in block 610.In addition, in some cases, being assigned to for the second lease generation The division of producer's system 106 of reason 102 can be at least partially based on the type of the second rental agency 102.For example, if second Rental agency 102 provides producer's system 106 of storage service by specific assigned, then offer also can be specifically allocated to The life of the second rental agency 102 is assigned between 102 subgroup of rental agency of producer's system 106 of storage service or resource Production person's system 106.
In block 908, dividing system 222 utilizes the production for being newly assigned to each of still available rental agency 102 The identity of person's system 106 updates remaining rental agency 102.
In some embodiments, process 900 can be used for adding rental agency 102 or replacement rental agency 102.At this In the case where sample, block 904 can identify all available producer's systems 106 for dividing in block 906.In some cases Under, it can be can be with producer's system 106 in the available identical producer's system 106 of earlier time section.In other cases, should Group producer's system 106 may be changed due to the loss of producer's system 106 or the addition of producer's system 106.? Wherein in the case where the one-to-one replacement of rental agency 102, new rental agency can be assigned the production that rental agency is just being replaced Person's system 106.In this case, it may include notifying to other rental agencies that block 906, which can be optional and block 908, New rental agency is assigned producer's system 106 of old rental agency now.
The exemplary producer based on hysteresis selects process
Figure 10 illustrates the embodiment for selecting process 1000 for the producer based on hysteresis.It can be by that can modify Selection weight relevant to producer's system 106 (is made with the selection for modifying selection such as producer's system 106 of producer's system For a part of block 410) any system implementation process 1000.For example, by rental agency 102, block of state 228 and can rent System of renting 224 (naming just a few) wholly or partly implementation process 1000.Although any number of system can integrally or Partly implementation process 1000, but discussed to simplify, it will be referring to specific 1000 each section of System describe process.

For accessing the example flow of the service of producer's virtual machine
Figure 12 illustrates the embodiment of the process 1200 for accessing the service at producer's virtual machine.It can be by can Manage any system implementation process 1200 of the service as provided by producer's virtual machine of the access from consumer's virtual machine.Example It such as, can be by consumer host 1104, rental agency 102, overlapping network proxy server 1114 and lease requester 1118 (only Lift several) wholly or partly implementation process 1200.Although any number of system can wholly or partly realize stream Journey 1200, but discussed to simplify, it will be referring to specific 1200 each section of System describe process.
In some cases, process 1200 can be used for so that consumer's virtual machine is able to access that is mentioned by producer's system The service of confession.Similarly, in some embodiments, process 1200 can be used for so that Consumer System is able to access that by producing Service provided by person's virtual machine.However, being discussed to simplify, by disappearing relative to the service for attempting access producer's virtual machine Expense person's virtual machine describes process 1200.
Process 1200 starts in block 1202, wherein the overlapping of such as consumer host 1104 (for example, consumer host A) Network proxy server 1114 receives the clothes from the access producer from consumer's virtual machine 1142 (for example, consumer virtual machine A') The request of business.Alternatively, or in addition to this, received request can be the data that will be provided to the producer in block 1202 Packet.For example, the data packet, which can be, will be used together or be easy to use the data of the service at the producer, consumer in conjunction with service The access to the producer has had been established in virtual machine.In some embodiments, which may include the packet with header, should Header shows that the request or the coating are addressed to virtual address X from address A relevant to consumer's virtual machine 1142.For example, institute Received packet can be as follows: { Α ', X, data } show that data are just sent to X from Α '.The data field of packet may include Convenient for executing the request and/or operation of request or operation at producer's virtual machine 1162.In certain embodiments, consumer Virtual machine 1142 may be not aware that address X is virtual address, but may think that address X refers to that the physics producer is on the contrary System.In addition, as previously mentioned, in some embodiments, overlapping network may include being different from or in addition to consumer's virtual machine Consumer System.In such embodiments, block 1202 may include realized from consumer host 1104 or by Consumer System hosted by consumer host 1104 receives the request of the service at the access producer.Similarly, producer master Machine may include being different from or producer's system in addition to producer's virtual machine, these producer's virtual machines can be configured to Consumer System provides service.
In decision block 1204, overlapping network proxy server 1114 is determined whether there is and 1142 phase of consumer's virtual machine Any not used producer's virtual machine lease closed.Determine whether there is any do not make relevant to consumer's virtual machine 1142 Producer's virtual machine lease may include access virtual machine mapping storage library 1150 to determine whether there is in consumer's void The quasi- relevant lease pond of machine 1142.In addition, in some cases, decision block 1204 can include determining that whether lease pond includes using In any unused lease of producer's virtual machine relevant to consumer's virtual machine 1142.
If overlapping network agency 1114 determines that there is no relevant to consumer's virtual machine 1142 in decision block 1204 Not used producer's virtual machine lease, then leasing requester 1130 in block 1206 obtains multiple leases to access the producer Virtual machine.It is described in further detail below in relation to Figure 14 for obtaining one or more leases to access one or more productions The example of the process of person's virtual machine.
In block 1208, overlapping network proxy server 1114 is attempted to establish and leases life obtained in block 1206 The connection of production person's virtual machine 1162.In some cases, block 1208 can store with the institute of overlapping network proxy server 1114 at Function establishes the relevant information of lease of each leased producer's virtual machine of connection.
After overlapping network proxy server 1114 establishes connection with leased producer's virtual machine in block 1208, or If overlapping network proxy server 1114 determines in decision block 1204 not to be made in the presence of relevant to consumer's virtual machine 1142 With producer's virtual machine lease, then process 1200 proceeds to block 1210.In block 1210, overlapping network proxy server 1114 Selection is from wherein accessing by leased producer's virtual machine 1162 of the requested service of consumer's virtual machine 1142.It can be used Any kind of selection algorithm such as poll least recently used selects producer's virtual machine 1162.In other cases, Producer's virtual machine 1162 can be selected based on the sequence of connection is established with producer's virtual machine 1162.In other cases, Producer's virtual machine 1162 can be randomly and/or based in block 1202 received service request to select the producer virtual Machine 1162.Alternatively, in some cases, 1114 accessible virtual machine mapping storage library of overlapping network proxy server 1150 in order to selecting producer's virtual machine 1142.It, can be with for example, the accessible lease pond of overlapping network proxy server 1114 By the lease pond be stored as identification can with the table of producer's virtual machine 1162, be stored in virtual machine mapping storage library 1150.
In some cases, overlapping network proxy server 1114 can choose the leased producer that load is lower than threshold value Virtual machine 1162.In this case, overlapping network proxy server 1114 can be empty lower than the producer of threshold value from load It is randomly chosen in quasi- machine 1162.Any of utilization rate that the load may refer to be related to producer's virtual machine 1162 estimates Amount.For example, load may refer to processor load, network connection load, multiple consumers with producer's virtual machine 1162 Lowest latency, the performance metric of producer's virtual machine 1162 etc. in connection, connection.
In addition, in some cases, each lease can be related to cost.For example, can for use each second, For transmit every Mbytes of handled data or for producer's virtual machine 1162 each calculating cycle come pair Consumer or entity relevant to consumer charge.In this case, overlapping network proxy server 1114 can be based on The producer virtual machine 1162 leased at original selection for the available producer's virtual machine 1162 leased.
In block 1212, overlapping network proxy server 1114 will be included in request header (for example, inner header) The address (for example, virtual address X) of the producer is changed to leased producer's virtual machine 1162 selected in block 1210 Address.Thus, for example, the received packet of institute now can be as follows in block 1202: Α ', Β ', data }.In some implementations In scheme, block 1212 can be optional.For example, in some embodiments, each leased producer's virtual machine 1162 It can be related to port.Therefore, instead of virtual address X to be changed to the address of leased producer's virtual machine 1162, can make Packet is transmitted to the trustship producer by port relevant to leased producer's virtual machine 1162.As the second example, can make Packet is transmitted to producer's host, and producer's host can for example determine the institute for receiving packet based on virtual address X Lease producer's virtual machine 1162.
In block 1214, overlapping network proxy server 1114 identifies the producer relevant to leased producer's virtual machine Host 1106.Producer's host can be identified by accessing the state table being stored in virtual machine mapping storage library 1150 1106。
In block 1216, overlapping network proxy server 1114 encapsulates the request with external header, which knows The producer's host 1106 not identified in block 1214 and consumer host 1104 relevant to consumer's virtual machine 1142.Cause This, is for example, packet now can be as follows: A, B Α ', Β ', data } }, show that Bao Zhengcong consumer host A is sent to life Production person's host B.Alternatively, in some cases it may make producer's host 1106 and the identity packet of consumer host 1104 The request header and packet for including in or being added to the received request in block 1202 can be as follows: { A, B, A', B', number According to, show that Bao Zhengcong consumer host A is sent to producer's host B.In this case, in stream relevant to block 1216 After the completion of journey, which includes single header rather than two headers, the two headers include inner header and external header.? In some embodiments, block 1216 may include and provide consumer's virtual machine 1142 of request in block 1202 and in block The identity of the relevant overlapping network of producer's virtual machine 1162 identified in 1210.Thus, for example, packet may indicate that request To ' or the first overlapping network it is related, this with " or the second overlapping network is in contrast, as follows: A, B, ', A', B', number According to }, show Bao Zhengcong consumer host A be sent to producer's host B and service request be sent to from consumer's virtual machine ' weight Included producer's virtual machine in folded network.Advantageously, in certain embodiments, by including with service request and right The identity of the overlapping network of the response of service request can reuse address between different overlapping networks.However, wherein Under each virtual machine and each system situation relevant to unique address, the identity for providing overlapping network be can be optionally 's.
In some embodiments, overlapping network proxy server 1114 can be from being stored in virtual machine mapping storage library Condition management table in 1150 determines the address information for accessing producer's virtual machine.The condition management table may include being used for Access the link information of leased producer's virtual machine 1162 selected in block 1210.In addition, condition management table can wrap Include the mapping of virtual address to producer's virtual machine address.In addition, condition management table can also include producer's virtual machine 1162 To the mapping of its corresponding producer's host.It is illustrated in Figure 15 such a shape for making virtual address be mapped to producer's virtual machine The example of state management table.
In block 1218, overlapping network proxy server 1114 is provided to the producer's host identified in block 1214 Request.The request can be provided to producer's host 1106 by network 202.
For handling the example flow of the request of the service at access producer's virtual machine
Figure 13 illustrates the embodiment of the process 1300 of the request for handling the service at access producer's virtual machine. Can by can handle access from consumer host received producer's virtual machine service any system implementation process 1300.For example, (can only be lifted by producer's host 1106, overlapping network proxy server 1116 and producer's virtual machine 1162 Several) wholly or partly implementation process 1300.Although any number of system can wholly or partly implementation process 1300, but discussed to simplify, it will be referring to specific 1300 each section of System describe process.
In some cases, process 1300 can be used for so that producer's virtual machine is capable of providing and is asked by Consumer System The service asked.Similarly, in some embodiments, process 1300 can be used for so that producer's system is able to access that by producing Service provided by person's virtual machine.However, discussed to simplify, it will be relative to providing to by the requested clothes of consumer's virtual machine Producer's virtual machine of the access of business describes process 1300.
Process 1300 starts in block 1302, wherein the overlapping of such as producer's host 1106 (for example, producer's host B) Network proxy server 1116 is received from consumer host 1104 and is requested.The request can be formatted for example as follows: A, B, ', A', B', data }, show that Bao Zhengcong consumer host A is received and is intended for producer's host B, and service is asked Ask be sent to from consumer's virtual machine ' producer's virtual machine included in overlapping network.In many cases, received request It is the request for accessing the service as hosted by producer's virtual machine 1162, producer's virtual machine is by 1106 support of producer's host Pipe.However, in some cases, received request can be data packet on the contrary, which is configured to virtual to the producer Machine 1162 provides data in order to execute the service for establishing access by consumer's virtual machine 1142, and consumer's virtual machine is by disappearing 1104 trustship of the person's of expense host.
In block 1304, overlapping network proxy server 1116 determines producer's virtual machine 1162 for receiving request (for example, producer virtual machine B').In some embodiments, block 1304 may include making external header institute from block 1302 Received request decapsulation.In this case, packet can be as follows: Α ', Β ', data }, show that Bao Zhengcong is consumed Person's virtual machine A' is received and is intended for producer's virtual machine B'.In this case, it is overlapped network proxy server 1116 accessible inner headers are to identify producer's virtual machine 1162.Alternatively, or in addition to this, overlapping network agency clothes Business device 1116 can identify producer's virtual machine 1162 for receiving request by access external header.
In some cases, overlapping network proxy server 1116 is to the producer's virtual machine identified in block 1304 1162 provide the request without external header.Therefore, packet can be as follows: Α ', Β ', data }.However, in other situations Under, which can be provided as being received from consumer host 1104, if the request is included in received request In be then included in external header.Therefore, packet can as received in block 1302 it is the same (for example, A, B, ', A', B' are several According to).
