Energy-Efficient Resource Allocation for Virtual Service in Cloud Computing Environment

For the past several years, using cloud computing technology has become popular. With the cloud computing service providers, reducing the physical machine number providing resources for virtual service in cloud computing is one of the efficient ways to decrease the energy consumption amount which in turn enhance the performance of data centers. In this study, we propose the resource allocation problem to reduce the energy consumption. ECRA-SA algorithm was designed to solve and evaluate through CloudSim simulation tool compared with an FFD algorithm. The experimental results indicate that the proposed ECRA - SA algorithm yields a higher performance in comparison with an FFD algorithm.
