INFORMATION PROCESSING SYSTEM, DATA CENTER, SYSTEM MIGRATION METHOD, AND PROGRAM

摘要

The objective of the present invention is to allow smaller-scale migration to a data center in migration of systems between data centers. This information processing system is provided with a plurality of data centers (100) in which one or more virtual data centers (200) are built. A processing device (150) of a data center (100) executes processing for one or more virtual machines (220) configuring each of the virtual data centers (200). A construction program storage unit (120), in order to accommodate each of the virtual data centers (200), stores a construction program (300) for constructing the virtual data center (200) upon the processing device (150). A migration control unit (110) determines a migration destination data center (100) for the virtual data center (200) and transmits the construction program (300) corresponding to the virtual data center (200) to the migration destination data center (100).
