INSTANCE ARRANGEMENT DEVICE, INSTANCE ARRANGEMENT METHOD, INSTANCE ARRANGEMENT PROGRAM, AND INFORMATION PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an instance arrangement device, method, and program for arranging an instance that represents a virtual processing device in a physical information processing device in such a way as to achieve high response performance.;SOLUTION: An instance arrangement device 101 executes arrangement that satisfies a constraint condition that an allowance regarding each information processing device 211 is not exceeded, and a constraint condition that arrangement destinations at which instances are arranged are mutually exclusive between services realized by the instances. When an arrangement pattern that satisfies the former constraint condition is followed, each information processing device can process the arranged instances in the range of allowances that the information processing device has. When an arrangement pattern that satisfies the latter constraint condition is followed, even if a load pertaining to one service increases, surplus capacity pertaining to an information processing device 211 in which a service different from the one service is arranged is not susceptible to the one service.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
