Energy consumption has been a main concern to the environment as the scale of cloud data centers become larger due to the ease of internet usage, storage and processing on cloud. As a consequence of establishment of large number of data centers, the energy consumption grows rapidly. Also they contribute in the energy consumed worldwide and consequently to the environmental drawbacks like carbon emission. Virtualization technologies provide the ability to transfer virtual machines between the physical machines using live VM migration in cloud computing. Dynamic server consolidation is an efficient way for energy conservation in cloud by decreasing the total number of active physical machines.
