Green cloud computing: A review on efficiency of data centres and virtualization of servers
Fatima Shakeel, Seema Sharma · 2017
Since the performance improvement has always been in demand but the ever increasing energy/ power consumption of computing systems and emission of carbon dioxide in the environment has limited this improvement of performance. Therefore, there is much need of optimizing the power consumption of such systems. Considering cloud computing to be the focus of this review, we need to make them energy efficient. Up to now, Data Centers have contributed a lot in making cloud computing powerful. Thus, there is an increasing demand for Data Centers and this will tend to increase in future as well. This increase in demand has increased the energy consumption by data centers. Hence, there is an utmost need to take sufficient measures to lower the risk factors associated with increased energy demand. The fundamental objective of this review is to analyze the various techniques that have been implemented so far to reduce the consumption of energy by cloud computing systems. These techniques mainly focus on the virtualization of machines that has proved the revolutionary application area of green IT.
