Description

The technology disclosed herein relates to a migration destination determination program, a migration destination determination device, and a migration destination determination method.

Conventionally, cyberattacks and physical destruction of managed systems are monitored, and when an incident occurs, the system in which the incident occurred is migrated.

For example, a management method has been proposed that optimizes both processing capacity and resource utilization efficiency by appropriately changing the configuration when performance degradation or performance surplus occurs with respect to the current resource allocation. In this method, it is determined whether or not the performance of the server whose performance is degraded or surplus is occurring and the performance of other servers are mutually influencing each other. Decide if a transition to equipment is appropriate. After confirming the feasibility of the migration policy, present the items to be improved, the time required for the migration, the cost, etc., and quantitatively show the advantages and disadvantages of the configuration change work.

Also, a system control device has been proposed that can run a new virtual machine even if there is no resource pool with sufficient free space. This device determines whether or not the surplus resource amount of the physical resources of the first physical resource pool is greater than or equal to the physical resource amount required to operate the target virtual machine. In addition, when the surplus resource amount of the first physical resource pool is less than the required resource amount, this device increases the surplus resource amount of the first physical resource pool to an amount equal to or greater than the required resource amount. Then, when the surplus resource amount of the first physical resource pool is greater than or equal to the required resource amount, this device operates the target virtual machine using the physical resources included in the first physical resource pool.

Each of the systems located at each of the multiple bases is linked, and when an incident occurs, there are cases where measures such as system migration are performed between each base. In this case, in order to ensure the continuity of the system, it is desirable to determine a more appropriate site as the migration destination.

As one aspect, the technology disclosed herein aims to determine an appropriate migration destination of a system between multiple bases.

An example of an embodiment according to technology disclosed herein will be described below with reference to the drawings.

As shown in FIG. 1, the migration destination determination device 10 according to this embodiment is connected to each of a plurality of systems 30A, 30B, 30C, 30D, 30E, . . . via a network. Hereinafter, when the systems 30A, 30B, 30C, 30D, 30E, .

Each system 30 operates on a virtual server built on one or more server devices, which are physical resources arranged at each of a plurality of bases such as data centers. Each system 30 outputs log information indicating the state of the system in operation at any time, and transmits the log information to the migration destination determination device 10 . The log information also includes information that can identify whether an incident has occurred.

In addition, each system 30 is composed of a pair of an active system and a standby system, and the active system 30 and the standby system 30 are arranged at different bases.

The migration destination determination device 10 functionally includes a monitoring unit 12, a selection unit 14, and a determination unit 16, as shown in FIG. In addition, a system DB (Database) 22 and a site DB 24 are stored in a predetermined storage area of the migration destination determination device 10 .

The monitoring unit 12 monitors each of one or more systems operating at each of the plurality of bases. Specifically, the monitoring unit 12 acquires the log information transmitted from each system 30, and if the log information includes information indicating the occurrence of an incident, the incident in the system 30 that transmitted the log information to detect the occurrence of

When the monitoring unit 12 detects the occurrence of an incident, the monitoring unit 12 sends the active system 30 and the standby system 30 where the incident occurred to a transition control unit (not shown) that controls switching and transition between the active system and the standby system. command to switch between As a result, the transition control unit causes the standby system 30 to start operating as the active system 30 .

Further, when detecting the occurrence of an incident, the monitoring unit 12 notifies the selection unit 14 of identification information (hereinafter referred to as “system ID”) of the system 30 related to the incident. The incident-related system 30 is a system that needs to be transferred to another site. When an incident occurs in an active system 30, it is the standby system 30 paired with the system 30. When an incident occurs in the standby system 30, it is the system 30 itself.

When the occurrence of an incident is detected in any one of the systems 30, the selection unit 14 selects a site (hereinafter referred to as a "migration destination candidate") that is a candidate for the migration destination of the system 30 related to the incident. to select. The selection unit 14 selects a migration destination candidate capable of securing resources for migrating the incident-related system at a site other than the migration source site where the incident-related system 30 operates from among the plurality of sites. .

Specifically, the selection unit 14 refers to the "available resource amount" (details will be described later) stored in the site DB 24, acquires the available resource amount of each site, and secures the resource necessary for the migration of the system 30. Determine whether it is possible. If there is a site that can secure resources, the selection unit 14 selects that site as a migration destination candidate. If there is no base where resources can be secured, the selection unit 14 refers to the system DB 22 and derives the amount of resources that can be secured when the system 30 operating at each base is deleted or degraded.

Here, as shown in FIG. 3, the system DB 22 stores information such as "system ID", "ACT/SBY", "priority", "site", and "resource". "ACT/SBY" is information indicating whether the system 30 is active (ACT) or standby (SBY). “Priority” is the priority of operation based on the importance of the system 30 in question. In this embodiment, a case will be described in which the priority is set to three levels of "high", "middle", and "low". "Site" is identification information (hereinafter referred to as "site ID") of the site where the system 30 in question is located. “Resource” is the amount of resources required to construct the system 30 in question. In this embodiment, it is assumed that the amount of resources used by each of the virtual servers operating at each site is the same, and in the example of FIG. , representing the required amount of resources.

More specifically, the selection unit 14 determines whether the system 30 to be deleted or to be degraded based on whether the system 30 operating at each base is active or standby. The selection unit 14 also determines whether the system 30 is to be deleted or degraded based on the priority of the system 30 operating at each site. For example, the selection unit 14 determines that a standby system whose priority is lower than a predetermined priority is a system to be deleted, and degenerates an active system whose priority is higher than the predetermined priority. It can be determined as the target system.

In addition, the selection unit 14 derives the amount of resources that can be secured when the systems 30 operating at each site are deleted or degraded in descending order of priority and in order of standby system and active system. Then, the selection unit 14 sequentially selects sites as migration destination candidates in descending order of the amount of resources derived for each site that has reached the amount of resources required to migrate the incident-related system 30 . The selection unit 14 notifies the determination unit 16 of the site ID of the selected migration destination candidate site.

The determination unit 16 determines a migration destination candidate that satisfies a predetermined condition from among the migration destination candidates selected by the selection unit 14 as a migration destination base. The predetermined condition is a condition based on the distance between the migration destination candidate and the site where the incident occurred or the site where the system 30 to be migrated was operating (hereinafter referred to as "site related to migration source"). Note that the “distance” here is not limited to a distance represented by a specific numerical value, and may represent relatively far or near.

The determining unit 16 refers to the site DB 24 as shown in FIG. 4 to specify the distance between each of the migration destination candidates and the site related to the migration source. In the example of FIG. 4, the site DB 24 stores information such as "site ID", "region", and "available resource amount". The “region” is the region where the base exists, and is information for specifying the distance between each of the migration destination candidates and the base regarding the migration source. The "empty resource amount" is information used when determining whether or not the required resource amount can be secured.

As a condition based on the distance, for example, for the purpose of ensuring the continuity of the system 30 even in the event of a large-scale disaster such as an earthquake, a migration destination candidate that is the greatest distance from the base where the incident occurred is selected. conditions can be set. Also, for example, for the purpose of rapid migration of the system 30, it is possible to set a condition such that a migration destination candidate having the shortest distance from the site where the system 30 to be migrated was operating is selected. Furthermore, the conditions as described above may be switched and applied according to the cause of the incident that has occurred.

The determination unit 16 outputs migration information including the site ID of the determined migration destination site, information on the system 30 to be deleted or degraded, information on the system 30 to be migrated, and the like to the migration control unit.

The migration destination determination device 10 can be implemented by, for example, a computer 40 shown in FIG. The computer 40 includes a CPU (Central Processing Unit) 41 , a memory 42 as a temporary storage area, and a nonvolatile storage section 43 . The computer 40 also includes an input/output device 44 such as an input unit and a display unit, and an R/W (Read/Write) unit 45 that controls reading and writing of data to/from a storage medium 49 . The computer 40 also has a communication I/F (Interface) 46 connected to a network such as the Internet. The CPU 41 , memory 42 , storage unit 43 , input/output device 44 , R/W unit 45 and communication I/F 46 are connected to each other via bus 47 .

The storage unit 43 can be realized by a HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, or the like. A migration destination determination program 50 for causing the computer 40 to function as the migration destination determination device 10 is stored in the storage unit 43 as a storage medium. The migration destination determination program 50 has a monitoring process 52 , a selection process 54 and a determination process 56 . The storage unit 43 also has an information storage area 60 in which information constituting each of the system DB 22 and the site DB 24 is stored.

The CPU 41 reads out the migration destination determination program 50 from the storage unit 43 , develops it in the memory 42 , and sequentially executes the processes of the migration destination determination program 50 . The CPU 41 operates as the monitoring unit 12 shown in FIG. 2 by executing the monitoring process 52 . Further, the CPU 41 operates as the selection unit 14 shown in FIG. 2 by executing the selection process 54 . Further, the CPU 41 operates as the determination unit 16 shown in FIG. 2 by executing the determination process 56 . Also, the CPU 41 reads information from the information storage area 60 and develops each of the system DB 22 and the site DB 24 in the memory 42 . As a result, the computer 40 that has executed the migration destination determination program 50 functions as the migration destination determination device 10 . Note that the CPU 41 that executes the program is hardware.

Note that the function realized by the migration destination determination program 50 can also be realized by, for example, a semiconductor integrated circuit, more specifically an ASIC (Application Specific Integrated Circuit) or the like.

Next, the operation of the migration destination determination device 10 according to this embodiment will be described. Here, as shown in FIG. 3, the information of each system 30 shall be memorize|stored in system DB22. FIG. 6 shows the information of each system 30 by priority and by site, and shows a diagram in which the systems 30 paired by the active system and the stand-by system are connected by dashed lines.

Each of the plurality of systems 30 outputs log information indicating the state of the operating system as needed and transmits the log information to the migration destination determination device 10 . Then, the migration destination determination process shown in FIG. 7 is executed in the migration destination determination device 10 . Note that the migration destination determination process is an example of a migration destination determination method of technology disclosed herein.

In step S10, the monitoring unit 12 acquires the log information transmitted from each system 30, and based on whether the log information contains information indicating the occurrence of an incident, any system 30 has an incident. Determine whether or not it has occurred. If an incident has occurred, the process proceeds to step S20, and if no incident has occurred, the determination of this step is repeated.

Here, as shown in FIG. 6, it is assumed that an incident has occurred in system B operating at site 1 . In this case, the standby system B operating at the site 4 is switched to the active system. Along with this, it is necessary to newly migrate the standby system B to another base.

In step S<b>20 , the monitoring unit 12 instructs the transition control unit to switch between the active system 30 in which the incident occurred and the standby system 30 . In addition, the monitoring unit 12 notifies the selection unit 14 of the system 30 related to the incident, that is, the system ID of the system 30 to be migrated (here, “system B (SBY)”).

Next, in step S30, the selection unit 14 executes selection processing. Here, the selection process will be described in detail with reference to FIG.

In step S<b>31 , the selection unit 14 refers to the system DB 22 and specifies the amount of resources required to construct the system 30 indicated by the system ID notified from the monitoring unit 12 . Then, the selection unit 14 refers to the "free resource amount" in the site DB 24 and determines whether or not there is a site other than the migration source site that can secure the necessary resource amount. If there is a base where resources can be secured, the process proceeds to step S36. If there is no base where resources can be secured, the process proceeds to step S32.

In step S32, in order for the selection unit 14 to select a migration destination candidate that can secure the necessary resource amount by deleting or degenerating another system 30, a variable for specifying the system 30 to be deleted or degraded Set i to 1. Here, as shown in FIG. 9, the conditions of the system 30 to be deleted or degraded are determined in advance based on the priority of the system 30 and whether it is active or standby. In the example of FIG. 9, the order of i=1, 2, .

Next, in step S33, the selection unit 14 determines whether or not the i-th round condition has reached the same level as the priority of the system 30 to be shifted and whether it is the active system or the standby system. This determination is for terminating the process with the condition immediately before, in order to avoid deleting or degenerating systems 30 having the same or higher priority as the system 30 to be migrated. If the i-th round condition has reached the same level as that of the system 30 to be shifted, the process proceeds to step S39, and if it has not reached the same level, the process proceeds to step S34.

In step S<b>34 , the selection unit 14 derives the amount of resources that can be secured by deleting or degenerating the system 30 that satisfies the conditions of the i-th round for each site other than the migration source site.

Here, the amounts of free resources at sites 1, 2, and 3 other than site 4, which is the migration source site, are the same, and the amounts of resources that need to be secured by deleting or degenerating other systems 30 are the same amount. In this case, according to the conditions in FIG. 9, the first round condition is "delete the system with low priority and SBY". ) applies.

The selection unit 14 refers to the system DB 22 to specify the amount of resources used by the system 30 in question, and accumulates the amount of resources that can be secured for each site as shown in FIG. 10 .

Next, in step S35, the selection unit 14 determines whether or not there is a site that reaches the amount of resources required to be secured by deleting or degenerating the systems 30 that meet the conditions up to the i-th round. If there is a site that reaches the resource amount that needs to be secured, the process proceeds to step S36, and if not, the process proceeds to step S37. Here, since there is no site that reaches the required amount of resources, the process proceeds to step S37.

In step S37, it is determined whether or not i is greater than N ("7" in the example of FIG. 9) representing the order of the last condition. If i>N, the process proceeds to step S39. If i≦N, the process proceeds to step S38, the selection unit 14 increments i by 1, and the process returns to step S33. Here, since i=1, i=2 in step S38, and the process returns to step S33.

Since the condition of the second round is "delete system with low priority and ACT", system G (ACT) and system F (ACT) of location 3 are applicable. As shown in FIG. 10, the selection unit 14 accumulates the amount of resources used by the corresponding system 30 for each base as the amount of resources that can be secured in the results of the first round.

Since there is no site that reaches the amount of resources required to be secured even under the conditions of the second round, the third round is executed. Since the third round condition is "delete the system of middle priority and SBY", the system E (SBY) of the base 1 and the system C (SBY) of the base 2 are applicable. As shown in FIG. 10, the selection unit 14 accumulates the amount of resources used by the relevant system 30 for each base as the amount of resources that can be secured in the results up to the second round.

Since there is no site that reaches the amount of resources required to be secured even under the conditions of the third round, the fourth round is executed. Since the fourth round condition is "medium priority and degenerate ACT system", system D (ACT) at base 2 and system E (ACT) at base 3 are applicable. As shown in FIG. 10, the selection unit 14 selects, for each site, the amount of resources that can be reduced by degeneracy among the amounts of resources used by the system 30 in question, as the amount of resources that can be secured, up to the third round. pile up on the results of As for the amount of resources that can be reduced by degeneracy, it suffices to determine in advance to what size degeneracy is possible for each system 30 .

After the end of the fourth round, the site 2 and the site 3 reach the amount of resources that need to be secured.

In step S36, the selection unit 14 selects bases that can secure the required amount of resources as migration destination candidates. If there are multiple bases that can secure the required amount of resources, all of the multiple bases are selected as migration destination candidates. Here, base 2 and base 3 are selected as migration destination candidates. Then, the selection unit 14 notifies the determination unit 16 of the site ID of the site selected as the migration destination candidate, and the process returns to the migration destination determination process (FIG. 7).

In step S39, the selection unit 14 notifies the determination unit 16 that there is no migration destination candidate as a selection result, and the process returns to the migration destination determination process (FIG. 7).

Next, in step S40 of FIG. 7, the determining unit 16 determines whether or not there are a plurality of migration destination candidates selected by the selecting unit 14. FIG. If there is more than one, the process proceeds to step S50, and if there is one, the process proceeds to step S60. When the selection unit 14 notifies that there are no migration destination candidates, the determination unit 16 performs processing such as notifying the user of that fact.

In step S50, the determination unit 16 determines a destination candidate satisfying a predetermined condition based on the distance between the migration destination candidate and the base relating to the migration source as the migration destination base from among the plurality of migration destination candidates. Here, base 2 and base 3 are selected as migration destination candidates. Also, the incident occurred at site 1, and the migration source of the system to be migrated was site 4. Assume that a distance-based condition is defined to select the migration destination candidate that has the greatest distance between the migration destination candidate and the site where the incident occurred. In this case, referring to the site DB 24 shown in FIG. 4, site 3 (Kinki), which is farther from site 1 (Hokkaido), is determined as the migration destination. Further, it is assumed that a distance-based condition is set to select a migration destination candidate that minimizes the distance between the migration destination candidate and the migration source base. Also in this case, base 3 (Kinki), which is closer to base 4 (Kyushu), is determined as the migration destination.

On the other hand, in step S60, the determination unit 16 directly determines one migration destination candidate as the migration destination.

Next, in step S70, the determining unit 16 outputs migration information including the site ID of the determined migration destination site, information about the system 30 to be deleted or degraded, information about the system 30 to be migrated, etc. to the migration control unit. , the migration destination determination process ends.

As described above, according to the migration destination determination device according to the present embodiment, when an incident occurrence is detected in any one of one or a plurality of systems operating at each of a plurality of bases, the migration destination Select candidates. A migration destination candidate is a migration destination candidate that can secure resources for migrating the incident-related system at a site other than the migration source site where the incident-related system operates, among the plurality of sites. Then, among the migration destination candidates, the migration destination base is determined from among the migration destination candidates that satisfy a predetermined condition for the distance between the migration destination candidate and the base relating to the migration source. As a result, it is possible to determine an appropriate migration destination of the system among the plurality of bases.

In the above embodiment, a case has been described in which a migration destination is determined based on a distance condition as soon as a migration destination candidate capable of securing the required amount of resources is found, but the present invention is not limited to this. For example, all bases satisfying any one of a plurality of conditions based on priority and whether they are active or standby (for example, i=1 to 4 conditions shown in FIG. 9) are extracted. The migration destination may be determined based on the conditions of Also, for example, after narrowing down the bases based on distance conditions such as being at least a predetermined distance from the base where the incident occurred, the migration destination is determined based on the priority and whether it is an active system or a standby system. Candidates may be selected.

Further, in the above embodiment, when there is only one migration destination candidate, the case where that migration destination candidate is determined as the migration destination has been described, but the present invention is not limited to this. If the condition based on the distance is determined by a predetermined numerical value (for example, the distance is more than a predetermined distance from the base where the incident occurred), even if there is only one migration destination candidate, if the distance condition is satisfied, You may make it determine as a migration destination.

In this case, if the migration destination candidate has not been determined as the migration destination, the processing for selecting the migration destination candidate is continued by returning to step S38 shown in FIG. may

Further, when the condition based on the distance is defined by a predetermined numerical value, there may occur a case where the corresponding destination does not exist in step S50 of the destination determination process (FIG. 7). In this case as well, the process of selecting the migration destination candidate may be continued by returning to step S38 shown in FIG. 8 in the same manner as described above.

Further, the priority and the predetermined condition based on whether the system is active or standby in the above embodiments are not limited to the example in FIG. After the standby systems are targeted for deletion or degeneration in descending order of priority, the active systems may be deleted or degraded in descending order of priority. In addition, a system with a low priority and a system with a medium priority and a standby system may also be targeted for degeneracy first and then deleted.

Further, when determining the migration destination from the migration destination candidates, in addition to the distance condition, other conditions may also be used as indicators for determination. For example, a condition such as selecting a base with a lower average priority of systems operating at each base may be added.

In addition, in the above embodiment, the case of excluding the migration source base where the system to be migrated was running from the migration destination candidates was explained, but in addition, isolated bases, bases where incidents occurred, etc. are also excluded. You may

Also, in the above-described embodiment, the migration destination determination program has been pre-stored (installed) in the storage unit, but the present invention is not limited to this. The program according to the technology disclosed herein can also be provided in a form stored in a storage medium such as a CD-ROM, DVD-ROM, USB memory, or the like.
