Management system and management method for migrating a business system operating on a target infrastructure

A management method for infrastructure system, which is executed by a management system,

• an infrastructure system being configured to provide a resource for operating a business system and including a plurality of infrastructures with different architecture,
• the management system including at least one computer including:
• a processor;
• a storage device coupled to the processor;
• and a network interface coupled to the processor,
• the plurality of infrastructures including:
• a first infrastructure constructed by at least one server apparatus, at least one switch, and at least one storage system;
• and
• a second infrastructure constructed by at least one server apparatus,
• the management method for infrastructure system including:
• a first step of monitoring, by the at least one computer, a usage state of the resource of the business system operating on each of the plurality of infrastructures;
• and
• a second step of analyzing, by the at least one computer, a previous usage amount of the resource of the business system based on the usage state of the resource of the business system, determining which of the first infrastructure and the second infrastructure is to be used for the business system based on a result of analyzing the previous usage amount of the resource of the business system, and storing a result of determining as a first determination result;
• a third step of identifying, by the at least one computer, a target infrastructure, which is an infrastructure for which the resource is predicted to become insufficient among the plurality of infrastructures, based on the usage state of the resource of each of a plurality of business systems, and storing the target infrastructure as a second determination result;
• a fourth step of selecting, by the at least one computer, at least one business system being the migration target from among a plurality of business systems operating on the target infrastructure based on the first determination result and the second determination result;
• and
• a fifth step of migrating, by the at least one computer, the at least one selected business system.
