Power consumption of IaaS Cloud is growing at a rapid pace during the last decade. This leads to high operational and maintenance cost, and also reducing the profit margin of IaaS Cloud providers. Apparently profit margin depends on operational cost and revenue earned to comply with the Service Level Agreement (SLA) on the basis of achieved performance level. In this paper, the authors are building the relationship between energy consumption of servers and fulfillment of SLA (QoS) in IaaS Cloud. So they propose a framework to maximize revenues from SLA achieved requests on the energy efficient resource management in IaaS Cloud, in which the servers are equipped with DVFS module. Servers are not allowed to be turned on or turned off.
