[0030] The policy manages the mapping of required storage pool 202 characteristics to instance attributes.

[0031] The management system 100 holds, for example, instance management information 700 for managing instances, and connection management information 800 for managing the linkage of instances.

[0032] The policy management information 411 may be set for each business flow or for each user.

[0033] FIG. 7 is a diagram illustrating an example of the data structure of instance management information 700 held by the management system 100 of the first embodiment.

[0034] The management system 100 holds instance management information 700 for each business flow. The instance management information 700 stores entries including an instance ID 701, an owner 702, an instance summary 703, and an environment ID 704. One entry exists for one instance.

Processing content 804 is a field that stores information indicating processing related to instance collaboration.

[0040] FIG. 9 is a flowchart illustrating an overview of the process executed by the management server 200 according to the first embodiment.

[0041] When a management server 200 included in a platform 101 having a storage pool 202 receives a volume allocation request from a developer or an operator of a business system, the management server 200 executes the process described below. The volume allocation request includes business flow identification information and an instance (target instance) ID.

[0042] First, the management server 200 executes an instance attribute specification process (step S101). In the instance attribute specification process, the attribute of the target instance is specified. The details of the process will be described later.

[0043] Next, the management server 200 executes a storage pool search process (step S102). In the storage pool search process, candidates for the storage pool 202 are searched for. The details of the process will be described later.

[0044] In the first embodiment, the management server 200 searches for an available storage pool 202 from among the storage pools 202 in the platform 101 in which the management server 200 is included.

[0045] 9 may be executed by the management server 200 included in the platform 101 that does not have the storage pool 202. In this case, the management server 200 included in the platform 101 that does not have the storage pool 202 can execute the same process by communicating with the management server 200 included in the platform 101 that has the storage pool 202. The process may be executed using storage pool management information 410 (see FIG. 10), which will be described later.

[0046] 9 may be executed by a management server 200 included in the platform 101 that centrally manages the storage pools 202 in the computer system. In this case, the management server 200 holds storage pool management information 410 as shown in Fig. 10. An entry of the storage pool management information 410 shown in Fig. 10 includes a platform ID 511. The platform ID 511 is a field that stores the ID of the platform 101 that provides the storage pool 202. The management server 200 searches for an available storage pool 202 from among the storage pools 202 in the computer system.

[0047] 11A and 11B are flowcharts illustrating an example of an instance attribute specification process executed by the management server 200 of the first embodiment. Fig. 12 is a diagram illustrating an example of instance attribute information generated by the management server 200 of the first embodiment.

[0048] The management server 200 initializes the instance attribute information 1200 (step S201).

[0049] Here, the instance attribute information 1200 will be described. The instance attribute information 1200 includes external linkage 1201, public 1202, and migration / duplication 1203. Note that the fields are not limited to those described above. Any of the fields described above may not be included, and other fields may be included.

[0050] External link 1201 is a field that stores a flag indicating whether the owner links with an instance other than its own (for example, the developer who requested the volume allocation). If the owner links with an instance other than its own, "1" is set, and if the owner does not link with an instance other than its own, "0" is set.

[0051] Public 1202 is a field that stores a flag indicating whether the environment in which the instance runs is a public cloud system. If the environment in which the instance runs is a public cloud system, "1" is set, and if the environment in which the instance runs is not a public cloud system, "0" is set.

[0052] Migration / duplication 1203 is a field that stores a flag indicating whether the process content related to the instance cooperation is migration or duplication of an instance to a public cloud system. If the process content related to the instance cooperation is migration or duplication of an instance to a public cloud system, "1" is set, and if the process content related to the instance cooperation is not migration or duplication of an instance to a public cloud system, "0" is set.

[0053] In step S201, the management server 200 generates instance attribute information 1200 in which the external linkage 1201, the public 1202, and the migration / duplication 1203 columns are blank.

[0054] The management server 200 inquires of the management system 100 about the owner of the instance that is the connection source of the target instance (step S202). The inquiry includes the identification information of the business flow and the ID of the target instance.

[0055] When the management system 100 receives this inquiry, it refers to the connection management information 800 corresponding to the business flow and searches for an entry in which the ID of the target instance is stored in the connection destination instance ID 803. The management system 100 acquires the instance ID from the connection source instance ID 802 of the searched entry. The management system 100 refers to the instance management information 700 corresponding to the business flow and searches for an entry in which the acquired instance ID is stored in the instance ID 701. The management system 100 responds to the management server 200 with the value stored in the owner 702 of the searched entry.

[0056] If there are multiple connection source instances, the management system 100 notifies the owner of each instance.

[0057] Based on the response to the inquiry, the management server 200 determines whether or not the owners of all the instances from which the target instance is connected are "our own company" (step S203).

[0058] If the owners of all the instances that are connection sources of the target instance are "our company," the management server 200 sets "0" to the external linkage 1201 of the instance attribute information 1200 (step S204), and then proceeds to step S206.

[0059] If the owner of at least one connection source instance of the target instance is "other company", the management server 200 sets "1" to the external linkage 1201 of the instance attribute information 1200 (step S205), and then proceeds to step S206.

[0060] In step S206, the management server 200 inquires of the management system 100 about the platform 101 on which the target instance runs (step S206). The inquiry includes the business flow identification information and the ID of the target instance.

[0061] When the management system 100 receives the inquiry, it refers to the instance management information 700 corresponding to the business flow and searches for an entry in which the ID of the target instance is stored in the instance ID 701. The management system 100 responds to the management server 200 with the value stored in the environment ID 704 of the searched entry.

[0062] Based on the response to the inquiry, the management server 200 determines whether the platform 101 on which the target instance runs is a public cloud system (step S207).

[0063] If the platform 101 on which the target instance runs is not a public cloud system, the management server 200 sets "0" to the public 1202 of the instance attribute information 1200 (step S208), and then proceeds to step S210.

[0064] If the platform 101 on which the target instance runs is a public cloud system, the management server 200 sets "1" to the public 1202 of the instance attribute information 1200 (step S209), and then proceeds to step S210.

[0065] In step S210, the management server 200 inquires of the management system 100 about the processing content of the link in which the target instance is the connection source (step S210). The inquiry includes the identification information of the business flow and the ID of the target instance.

[0066] When the management system 100 receives the inquiry, it refers to the connection management information 800 corresponding to the business flow and searches for an entry in which the ID of the target instance is stored in the connection source instance ID 802. The management system 100 responds to the management server 200 with the value stored in the process content 804 of the searched entry.

[0067] When there are multiple connection destination instances, that is, when there are multiple connectors, the management system 100 notifies the processing content for each connector.

[0068] Based on the response to the inquiry, the management server 200 determines whether or not migration / duplication is included in the process content of the collaboration in which the target instance is the connection source (step S211).

[0069] If migration / duplication is not included in the process content of the collaboration in which the target instance is the connection source, the management server 200 sets "0" to migration / duplication 1203 of the instance attribute information 1200 (step S215), and then ends the process.

[0070] When the process contents of the linkage in which the target instance is the connection source include migration / duplication, the management server 200 queries the platform 101 on which the instance to which the target instance to be migrated / duplicated is connected runs (step S212). The query includes the business flow identification information and the ID of the instance to which the target instance is connected.

[0071] When the management system 100 receives the inquiry, it refers to the instance management information 700 corresponding to the business flow and searches for an entry in which the ID of the connection destination instance is stored in the instance ID 701. The management system 100 responds to the management server 200 with the value stored in the environment ID 704 of the searched entry.

[0072] Based on the response to the inquiry, the management server 200 determines whether or not a public cloud system is included in the platform 101 on which the instance to which the target instance to be migrated / replicated is connected is running (step S213).

[0073] If a public cloud system is included in the infrastructure 101 on which the instance to which the target instance to be migrated / replicated is connected is running, the management server 200 sets "1" to migration / duplication 1203 in the instance attribute information 1200 (step S214), and then terminates the processing.

[0074] If a public cloud system is not included in the infrastructure 101 on which the instance to which the target instance to be migrated / replicated is connected is running, the management server 200 sets "0" to migration / duplication 1203 in the instance attribute information 1200 (step S215), and then terminates the processing.

[0075] A management system 100 such as an iPaaS (Integration Platform AS a Service) and a CMP is used by a user who develops or operates a business system, and has not been used in the past to manage a platform 101. This embodiment is characterized in that information held by the management system 100 is used to support "selection of a storage pool 202", which is one of the management operations of the platform 101.

[0076] FIG. 13 is a flowchart illustrating an example of a storage pool search process executed by the management server 200 of the first embodiment.

[0077] The management server 200 refers to the policy management information 411 based on the instance attribute information 1200, and identifies the characteristics (storage characteristics) required for the storage pool 202 (step S301).

[0078] Specifically, the management server 200 searches for an entry in which an attribute corresponding to a field in which "1" is set is stored in the instance attribute 602. The management server 200 obtains the value stored in the storage characteristics 603 of the searched entry.

[0079] For example, when "1" is set in the external link 1201, an entry with "P001" as the policy ID 601 is searched for. In this case, "encryption" and "backup" are the storage characteristics.

[0080] The management server 200 refers to the storage pool management information 410 and searches for a storage pool 202 having the identified storage characteristics (step S302).

[0081] Specifically, the management server 200 searches the storage characteristics 502 for an entry in which a value corresponding to the identified storage characteristic is stored.

[0082] The management server 200 generates display information for displaying the search results, and outputs it to the administrator of the platform 101 having the storage pool 202 (step S303).

[0083] For example, if a storage pool 202 having the specified storage characteristics exists, the management server 200 generates display information for displaying the storage pool 202. If a storage pool 202 having the specified storage characteristics does not exist in step S302, the management server 200 generates display information for indicating that a storage pool 202 does not exist and for displaying the storage characteristics. The administrator of the platform 101 can set a new storage pool 202 in the platform 101 by referring to the storage characteristics.

[0084] As described above, in this embodiment, information held by the management system 100 that performs centralized management of business services can be utilized to assist in the selection of a storage pool that allocates storage space to a volume used by an instance.
