Abstract: An administrator executes provisioning of a volume that satisfies a reliability requirement without being aware of storage configuration. A third processing module is configured to acquire a provisioning request that includes a reliability requirement for reliability of a storage service provided from a first processing module to a second processing module, and a volume requirement for a primary volume provided to the second processing module by the storage service, determine, on the basis of the volume requirement and storage information, volume configuration information showing the configuration of the primary volume being provisioned from a logical storage area, and determine, on the basis of the volume configuration information, the reliability requirements, and the storage information, replication configuration information showing the configuration of a replication that uses the primary volume as a copy source.
