Patent ID: 7991893

Claim:
An information system comprising: a plurality of information systems, the information systems each including a network apparatus, one or more servers, and one or more storage systems, the information systems being in communication with each other via a network; and a performance index setting forth performance values of various types of CPUs operating on various server environments; wherein, when migration of an application is initiated at a first information system, the first information system is configured to send a migration request to one or more targeted information systems of the plurality of information systems, the migration request specifying network requirements, server requirements and storage requirements for running the application at a first level of performance, wherein each of the one or more targeted information systems determines whether the targeted information system has sufficient free capacity of network resources, server resources and storage resources to satisfy the specified network requirements and server requirements for running the application at the first level of performance, wherein each of the one or more targeted information systems sends a response to the first information system including results of whether the targeted information system has the sufficient free capacity, wherein when one or more of the targeted information systems has the sufficient free capacity, the first information system identifies the one or more targeted information systems having the sufficient free capacity as candidate information systems for receiving migration of the application, and wherein each targeted information system compares the performance value of a first type of CPU set forth in the server requirements with the performance value of a second type of CPU having available processing capacity at the targeted information system to determine whether the targeted information system has the sufficient free capacity to meet the server requirements.
