An Eco Algorithm for Dynamic Migration of a Group of Virtual Machines in a Server Cluster.

Huge amount of electric energy is consumed by information systems, especially servers in scalable clusters. In order to discuss how to reduce the electric energy consumption of servers, we first have to define a power consumption model, and computation model by which we can know how much electric power a server consumes to perform application processes and how long it takes to perform each process.

we consider a dynamic cluster where virtual machines are dynamically suspending and resuming depending on number of processes to be performed on servers. We newly propose a dynamic migration of a group of virtual machines (DMG) algorithm for a dynamic cluster in this research.
