Computer system and storage management method for allocating storage areas to containers based on storage characteristics and connection information in a multi-base cloud environment

A computer system with clouds of a plurality of bases and a management server, wherein

• the cloud includes a compute server on which a container execution platform for executing a container is built, and a storage server that provides a storage area for storing data,
• the management server stores a storage characteristic of a storage area of a storage server in the cloud of each base and connection information to the storage area,
• the compute server,
• acquires, from the management server, a storage characteristic and connection information of the storage area in the base to which the compute server belongs,
• determines a storage area to be allocated to the container of the container execution platform based on the storage characteristic, and
• allocates the determined storage area to the container based on the connection information,
• the management server or the storage server stores information on a volume of the storage server that is used by an application in a previously existing container, and
• the compute server allocates the volume used by the storage server to an application of a container to be reconstructed based on the information on the volume.

• allocates the determined storage area to the container based on the connection information, and
• the management server,
• determines, when the container is migrated from the cloud of a base of a migration source to the cloud of a base of a migration destination different from the migration source, whether a storage area having a same storage characteristic as a storage area used by the container at the base of the migration source exists in the cloud at the base of the migration destination,
• sets, when a storage area having the same storage characteristic exists, the existing storage area with the storage characteristic in the container execution platform of the cloud of the migration destination, and
• specifies, when a storage area having the same storage characteristic does not exist, a storage area having a storage characteristic similar to that of the storage area used by the container, based on a performance ratio between performance of the storage area at the base of the migration source and performance of the storage area at the base of the migration destination, and a cost ratio between cost of the storage area at the base of the migration source and cost of the storage area at the base of the migration destination.
