<P>PROBLEM TO BE SOLVED: To provide a virtual data center system. <P>SOLUTION: A virtual data center system includes plural data center systems, a provisioning system capable of transmitting/receiving information to/from the data center systems, and a statistical operation database for storing information on resources of the data center systems therein. The provisioning system uses the information on resources stored in the statistical operation database to compare a resource cost based on resources of the data center systems in an arbitrary generation in accordance with a use state of the data center systems by a user system used by a user with a resource cost based on resources of the data center systems in a generation currently used by the user. Then, the provisioning system calculates a resource cost to be reduced in the case of transition to the data center systems in the arbitrary generation and performs rearrangement of the data center systems from the currently used arrangement to the arrangement in the arbitrary generation in response to a control instruction from the user. <P>COPYRIGHT: (C)2013,JPO&INPIT |
