Description

  The present invention relates to a system configuration management apparatus, a system configuration management method, and a system configuration management program.

  In recent years, development and construction of IT (Information Technology) systems that perform various tasks using a computer have been extensive. When the IT system was first introduced, it took a relatively long time to develop it, and the system once constructed has been operated for several years. Also, the system had to be developed exclusively for each customer.

  On the other hand, as a trend over the past few years, operations corresponding to new business operations are being performed by adding functions or improving functions to a built system. In recent years, there have been many forms of system development that repeatedly add and improve such functions in a short period of time.

As a result, so-called lateral development, in which the same system is introduced into a plurality of companies, has been actively implemented. However, in such horizontal development, it is required to incorporate the unique requirements of each company into the system, and it is necessary to customize the system for each company.

  It is necessary to efficiently generate various variations of the system when adding, improving, and customizing functions to the system. Here, technologies related to system customization are disclosed in, for example, Patent Literature 1 and Patent Literature 2.

  The technique described in Patent Document 1 deploys a difference image corresponding to a difference between a master image and a target system after deploying a master image of the system when the target system is deployed on a computer.

  In the technique described in Patent Document 2, when a job is assigned to an isolated environment on a node of the grid system, a package necessary for execution of the job is additionally deployed to a package already deployed in the isolated environment.

  The existing system storage device 400 stores an existing system. In the example of FIG. 2, the existing system storage device 400 stores VM modules “VM2” and “VM4” as existing systems.

  The system configuration management apparatus 100 may be a computer that includes a CPU (Central Processing Unit) and a storage medium that stores a program, and that operates by control based on the program. Further, the system configuration information storage unit 131 and the existing system information storage unit 132 may be configured as individual storage media or a single storage medium.

  Next, the operation of the system configuration management apparatus 100 in the first exemplary embodiment of the present invention will be described.

  Here, it is assumed that the system configuration information 141 in FIG. 3 is set in the system configuration information storage unit 131. Further, it is assumed that the existing system information storage unit 132 is set with the existing system information 142 of FIG.

  FIG. 7 is a flowchart showing processing of the system configuration management apparatus 100 according to the first embodiment of this invention.

  First, the difference system configuration information generation unit 110 of the difference system configuration information generation unit 110 receives a configuration version of the construction target system from the user (step S101).

  For example, the difference system configuration information generation unit 110 receives the configuration version “6” from the user.

  The differential configuration management unit 111 acquires the system configuration information 141 from the system configuration information storage unit 131 (step S102).

  For example, the differential configuration management unit 111 acquires the system configuration information 141 of FIG.

  Based on the system configuration information 141 and the existing system information 142, the existing system search unit 112 includes all the components of the system configuration of the existing system among the configuration versions of the existing system included in the existing system information 142 as the system to be built. A configuration version that is included in the components of the system configuration and satisfies the condition that minimizes the number of differential configurations between the system configuration of the existing system and the system configuration of the construction target system is extracted (step S103). Here, the existing system search unit 112 sequentially acquires the configuration version indicated by the application target version from the configuration version of the configuration target system on the system configuration information 141, and searches on the existing system information 142. Then, the existing system search unit 112 determines whether or not the acquired configuration version matches any of the configuration versions of the existing system. Then, the existing system search unit 112 extracts the configuration version first determined to match any of the configuration versions of the existing system as the configuration version of the existing system that satisfies the above condition.

  For example, the existing system search unit 112 acquires the configuration versions of the system configuration information 141 in FIG. 3 in the order of “6”, “5”, “4”,... And searches the existing system information 142 in FIG. Then, the configuration version “4” of the existing system is extracted.

  If the configuration version of the existing system that satisfies the above conditions can be extracted, the system configuration existing system search unit 112 may extract the configuration version by another method. For example, the system configuration existing system search unit 112 compares the system configuration components of the existing system with the system configuration components of the construction target system based on the system configuration information 141, and the existing system that satisfies the above-described conditions May be extracted.

  The existing system search unit 112 extracts an existing system identifier corresponding to the extracted configuration version from the existing system information 142 (step S104).

  For example, the existing system search unit 112 acquires the existing system identifier “VM4” corresponding to the configuration version “4” from the existing system information 142 of FIG.

  The differential configuration management unit 111 refers to the system configuration information 141 and extracts a differential configuration between the configuration version of the construction target system and the configuration version of the existing system extracted in step S103 (step S105). Here, the differential configuration management unit 111 changes the system configuration elements (basic configuration, differential configuration) of the configuration version of the existing system from the system configuration components (basic configuration, differential configuration) of the configuration version of the construction target system. The component identifiers of the remaining difference components are extracted.

  For example, the differential configuration management unit 111 refers to the system configuration information 141 in FIG. 3, and removes the components of the system configuration of the configuration version “4” from the components of the system configuration of the configuration version “6”. The component identifiers “AP1Conf11” and “AP1Conf12” of the differential configuration are extracted.

  Based on the configuration version of the existing system extracted in step S103, the system identifier of the existing system extracted in step S104, and the component identifier of the differential configuration extracted in step S105, the differential configuration management unit 111 Difference system configuration information 151 is generated (step S106).

  For example, the differential configuration management unit 111 generates the differential system configuration information 151 in FIG.

  The differential configuration management unit 111 may generate a composite differential configuration based on the differential configuration extracted in step S105, for example, may generate the differential system configuration information 151 of FIG.

  Next, the activation unit 121 of the system construction unit 120 activates the existing system indicated by the difference system configuration information 151 (step S107).

  Here, when the existing system is a VM module, the activating unit 121 acquires the VM module indicated by the existing system identifier of the differential system configuration information 151 from the existing system storage device 400, generates an instance thereof, and the processing device 200. Deploy to.

  For example, the activate unit 121 acquires a VM module “VM4”, which is an existing system indicated by the differential system configuration information 151 in FIG. 5, and deploys the instance “VM4a” to the processing device 200 as shown in FIG.

  Next, the differential configuration application unit 122 applies the differential configuration indicated by the differential system configuration information 151 to the activated instance of the existing system (step S108).

  For example, the differential configuration application unit 122 applies the configurations “AP1Conf11” and “AP1Conf12”, which are the differential configurations indicated by the differential system configuration information 151 in FIG. 5, in order to the VM module instance “VM4a”.

  As a result, a system having a system configuration of configuration version “6” is constructed on the processing apparatus 200.

  Note that, as the differential configuration of the differential system configuration information 151, for example, when a composite differential configuration is set as in the differential system configuration information 151 of FIG. 6, the differential configuration application unit 122 has a configuration that is a composite differential configuration. “AP1Conf11 — 12” is applied to the instance “VM4a” of the VM module.

  Thus, the operation of the first exemplary embodiment of the present invention is completed.

  The system configuration information storage unit 131 stores system configuration information 141 indicating identifiers of one or more components of the system configuration corresponding to the identifiers of the plurality of system configurations.

  The existing system information storage unit 132 stores existing system information 142 including one or more identifiers of the system configuration of an existing system that can be activated.

  The differential system configuration information generation unit 110 includes all the components of the system configuration of the existing system among the system configuration identifiers of the existing system included in the existing system information 142, and are included in the components of the system configuration of the construction target system, and The system configuration identifier that satisfies the condition that minimizes the number of differential configurations between the system configuration of the existing system and the system configuration of the construction target system is extracted, and the extracted system configuration identifier and the extracted system configuration identifier are extracted. The identifier of the difference configuration between the system configuration and the system configuration of the construction target system is output.

According to the first embodiment of the present invention, a system having a system configuration customized based on a basic configuration can be efficiently constructed. The reason is that the existing system search unit 112 includes all the constituent elements of the system configuration of the existing system among the constituent versions of the existing system included in the existing system information 142, and The configuration version that satisfies the condition that minimizes the number of differential configurations between the system configuration of the existing system and the system configuration of the construction target system is extracted, and the extracted configuration version of the existing system and the extracted configuration version This is because the differential system configuration information 151 including the identifier of the differential configuration between the system configuration of the system and the system configuration of the construction target system is output. By using the existing system indicated by the difference system configuration information 151, the construction target system is efficiently constructed with fewer steps and less time than when the difference configuration is sequentially applied to the basic configuration. In addition, by registering a system with a frequently used system configuration as an existing system, the system can be constructed more efficiently. Also, according to the first embodiment of the present invention, the basic configuration is used. When managing a plurality of customized system configurations, the amount of data defining the system configuration can be reduced. The reason is that the components of a plurality of system configurations are defined by basic configurations and existing systems, and differential configurations applied to the basic configurations and existing systems, such as system configuration information 141 and differential system configuration information 151. Because.
