An Energy-efficient Migration Model of Processes with Virtual Machines in a Server Cluster
説明
In cloud computing systems, computation resources like CPU and storages are virtualized. Virtual machines are now widely used to support applications with virtual computation service and to perform application processes. Furthermore, virtual machines can migrate from a host server to a guest server while processes are being performed on the virtual machines. We have to reduce electric energy consumption of servers in server clusters. In this paper, we take advantage of the migration technologies of virtual machines to reduce the electric energy consumed by servers. We propose a simple virtual machine migration (SVM) algorithm to migrate a virtual machine to another energy-efficient server in order to reduce the electric energy consumption. We show the total electric energy consumption of the servers can be reduced in the SVM algorithm.
