RESOURCE ALLOCATION DEVICE, RESOURCE ALLOCATION PROGRAM, RECORDING MEDIUM, AND RESOURCE ALLOCATION METHOD

A resource allocation apparatus 100 is an apparatus that allocates resource utilization amounts of m consolidation subject servers S i to be consolidated to n consolidation destination servers (n < m). An allocation subject list S contains the resource utilization amount of each consolidation subject server S i . The resource allocation apparatus 100 calculates a deviation value of the resource utilization amount of each consolidation subject server S i in the allocation subject list S, and, based on the deviation value and a priority of each resource, calculates a total value with consideration given to the priority, and sorts the consolidation subject servers S i in descending order of the total value. An allocation unit 120 executes an allocation process on the consolidation subject servers S i sequentially starting with the one with the greatest total value. In the allocation process, the allocation unit 120 calculates a "dispersion P' sd " of each resource utilization amount assuming that the consolidation subject server S i is allocated to the consolidation destination server S' j , with consideration given to the priority ±, and determines a combination of the consolidation subject server S i and the consolidation destination server S' j that minimizes the "dispersion P' sd "
