A Switch Based Power Aware VM Consolidation Method for Cloud Datacenter

Ubiquitous access has made the cloud computing very popular. Due to its wide acceptability, size of cloud data center is increasing every day. The enormous size of the datacenter is posing a challenge to the cloud service providers in terms of huge electricity bills. It has its environmental impact too in terms of carbon footprint. Hence, managing the cloud resources in energy efficient way is the need of the hour. Researchers have proposed many energy efficient methods based upon the concept of switching off idle machines. There is very less focus on equally important network component i.e. switch. In the same direction we have proposed a Switch based Power Aware (SPA) VM consolidation method to minimize the energy consumption of the cloud data center by considering the utilization rate of physical machines as well as the switches of the cloud datacenter. The result of the proposed method shows a significant decrease in the energy consumption of the cloud datacenter.
