Study on Green Cloud Computing-A Survey

Cloud computing is basically known for its pay- as-you-go model. Cloud computing has made the tremendous impact on every business by the services it offers. Cloud computing offers the various services which made easier for every organization to carry out their business task with in less time. The services offered are: IaaS (Infrastructure as a service), PaaS (Platform as a service), SaaS (Software as a service) and many more services Before cloud computing we have had the traditional data centers, which offered us the same resources but somehow less than what the cloud computing is offering. The traditional data centers offered us storage service, computing service networking and many more. But installing of data centers cost too much to organization and thus led to more Co2 emissions, or greenhouse gases emissions. Data centers consumes lot of energy. Thus, with the advent of cloud computing there was shift in approach from traditional data centers to the cloud, which helped us in reducing the carbon foot print thus in this manner somehow cloud computing offers us the green and sustainable approach where shifting to the cloud is more sustainable and environmental friendly. In this paper we will discuss about different services, deployment models of the cloud, different matrices of energy consumption and if there is any energy efficient architecture exist, and finally we will discuss ours propose model.
