METHOD AND SYSTEM FOR MIGRATION BASED ON RESOURCE UTILIZATION RATE IN CLOUD COMPUTING

摘要

According to the present invention, a cloud computing system comprises: a plurality of physical machines, and a server for migration of a virtual machine and the physical machines. One or more physical machines include one or more virtual machines. The server selects a virtual machine for migration based on the network dependence among the virtual machines included in the physical machines. And a destination physical machine of the selected virtual machine for the migration is selected based on a resource utilization rate of the physical machines, thereby migrating the virtual machine of the migration target to the selected destination physical machine.
