Green cloud computing: A survey

Abstract

In the IT industry the growing technology that is in demand is Cloud Computing. Cloud Computing is an infrastructure for running HPC, enterprise and Web applications. Huge data centers are used in this industry. The growing demand of Cloud Computing has drastically increased the consumption of energy that is used in data centers and also leads to high carbon emission which is not environment friendly, and that is the most critical issue. Hence, to minimize the impact of e-wastes and harmful gases produced by data centres, on the environment energy-efficient solutions are required. And in order to design such solutions, deep analysis is required of Cloud with respect to their power efficiency. This paper focuses on the elements of Clouds which contribute to the total energy consumption and on security in such a power saving data centres we call them as Green Cloud Computers, and this technology is called as Green Cloud Computing. We have suggested the Virtualization technique for energy saving and security for the Green Cloud.
