RESOURCE ALLOCATION DEVICE, RESOURCE ALLOCATION METHOD, AND RESOURCE ALLOCATION PROGRAM

摘要

Resource use efficiency is improved while realizing quality guarantee of an application. A resource allocation. device 10 includes a storage unit 13 that stores resource capacity information 120 indicating a capacity of each of server resources 200, an SLI information collection unit 11 that acquires information regarding an SLI at a predetermined time interval with regard to each of a plurality of applications 2, and a resource allocation determination unit 12 that calculates an allocation resource amount of each application 2 using a moving average and a standard deviation of the acquired informs information regarding the SLI during a predetermined period, and determines server resources 200 which are allocation. destinations of the applications 2 by sorting the applications 2 in descending order of the allocation resource amounts and sequentially adding the allocation resource amounts of the sorted. applications 2 within a range which does not exceed a capacity of each server resource 200 in descending order of the allocation resource amounts.
