A survey on power aware virtual machine placement strategies in a cloud data center

Cloud computing is one of the fast spreading technologies for providing utility based IT services to users. These services are provided by large-scale virtualised data centers. As it is these data centers consume large amount of electrical energy for their operation and maintenance. Extensive research had been undertaken to reduce the power consumption of data center by bringing changes in the hardware technology of data center. Alternatively, virtualization can also be used to reduce the power consumption in a data center. Migration of virtual machines(VM), one of the key feature of virtualization can be used to consolidate workloads on fewer servers and thus switch off idle servers to conserve energy. The major concern in any server consolidation technique is the optimal choice of physical server for VM placement. This paper aims to summarise the available VM placement algorithm that takes into consideration the power consumption factor during VM migration. A survey of various solutions to VM placement based on bin packing strategy is discussed.
