<P>PROBLEM TO BE SOLVED: To provide a scale-out technique of a server capable of suppressing unnecessary consumption of computer resources and effectively performing load distribution. <P>SOLUTION: A scale-out system comprises: a host server 3 having a virtual server group consisting of a plurality of virtual servers; a monitoring server 4 having a function to monitor the virtual server group of the host server 3; a dependency relation management server 5 having a function to manage dependency relation of software of the virtual server group of the host server 3; and a configuration change server 6 having a function to make a request for configuration change to virtualization software for managing the virtual server group of the host server 3. The monitoring server 4 detects a virtual server that is the cause of heavy load, and the dependency relation management server 5 obtains a system depending on a process of the detected virtual server. The configuration change server 6 moves only the obtained system to a virtual server of a scale-out destination. <P>COPYRIGHT: (C)2012,JPO&INPIT |
