In this paper, the authors have emphasized on developing an eco-friendly cloud computing by turning the switches of idle CPUs of IaaS off, simultaneously they have focused on avoiding SLA violation for minimized energy consumption and operational cost. For the overall process, they have proposed algorithm. They feel that a hybrid approach to be used that consists of Power-Nap, DVFS and ant colony optimization. So that every techniques may gives its better part. As Security and QOS are constraint in Cloud computing, they should be prevented.
