Cloud computing has emerged as a flexible and powerful computing platform which offers different types of services to users. However, the energy consumption and carbon emission in cloud data center have massive impact on global environment triggering intense research in this area. Growth in demand for cloud based services is resulting in increasing of utilization of cloud resources and consequent increase in the energy consumption. While there is a need to maximize utilization of the resources, the energy consumption needs to be reduced. Therefore the users need to determine the operational optimal point which reduces the energy consumption for a desired value of resource utilization.
