A Review on Energy Aware VM Placement and Consolidation Techniques

Due to rapid growth in the area of high performance computing, resource allocation and multiplexing is done through virtualization technology. In virtualization process each VM has limited resources for software running on it and abstractions that are provided by it. Theses resources are managed through VM placement and consolidation. This technology is facing certain deficiencies, due to heterogeneity and scalability of workloads, migration cost and time. To reap its full benefits better techniques are needed in VM placement and consolidation techniques. In this paper we present exhaustive survey on the available placement and consolidation techniques and conclude that major issues to be solved in these techniques are workload consolidation, QOS, minimizing number of migrations and active physical hosts.
