<p>An objective of the present invention is to provide a virtual data center system. The virtual data center system comprises: a plurality of data center systems; a provisioning system whereby information can be sent to and received from the data center systems; and an operational statistics database for storing information relating to resources of the data center systems, wherein: using the information relating to the resources stored in the operational statistics database, the provisioning system compares: resource costs based on the resources of a desired generation of data center system, in accordance with usage circumstances of the data center systems from a user system used by a user; and resource costs based on resources of a generation of data center system currently being used by the user, and thereby calculates the resource costs that would be reduced in the event of migration to the desired generation of data center system; and the data center systems currently used by the user being re-arranged to the desired generation of data center system in response to a control command issued from the user system.</p> |
