<p>The purpose of the present invention is to provide an information processing system for implementing efficient assignment of virtual resources to physical resources. This information processing system has a plurality of physical resources connected to each other by a network, and an operation and management computer for managing virtual resources for logically consolidating a plurality of physical resources. The information processing system logically consolidates and determines physical resources to be assigned to virtual resources on the basis of the resource usage amount of the workload processed by the information processing system and the configuration information of a plurality of physical resources.</p>
