Virtual Machine Reallocation in Data Centers Through Multi Parameter Decision Making Model
One of the important challenges in data centers is resource allocation and efficient use of available resources. Virtualization is a new technique which facilitates the process of fair and efficient allocation of physical resources among virtual machines. In this technique, virtual machines running on highly loaded physical servers should be migrated to less loaded machines. The authors should decide when the migration should occur and also the source and the destination of movement. It is usual to consider some trivial parameters of servers in decision making procedure.
