SCALE CONTROL SERVER, SCALE CONTROL METHOD, AND SCALE CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce wasteful operation cost of a virtual server by scale-controlling a system according to a load condition.;SOLUTION: In a case where a job execution request is received from a client terminal, based on an execution condition of the job which a job management database stores and a load state which a resource monitor part monitors, such number of servers as execute the job is decided, and the job is executed. Further, the execution time is stored in a process history database as an execution result, and based on the execution time of the job made to be stored by a job management part, an execution schedule stored in a schedule management database, and the time managed by a buffer, the execution schedule or the buffer is updated to be the execution time of the job.;COPYRIGHT: (C)2015,JPO&INPIT
