Energy Efficiency for Cloud Computing Applications: A Survey on the Recent Trends and Future Scopes

One of the upcoming technologies is ‘Cloud Computing’ which has seen enormous growth in the recent years with an aim to deliver computing as a utility. Fulfilling this technological demand is not an easy task. Huge data centers consisting large volume of data, large number of servers and various other auxiliary hard ware constitutes the infrastructure needed to support Cloud Computing. The datacenters are set up on a large-scale consisting of many computing nodes and use a tremendous quantity of electrical power which led to higher operational outlays. This increase in energy consumption, demands to rethink the energy efficiency of cloud infrastructures. Nevertheless, we need to analyze the current status prior to changing anything to the infrastructure. One of the key research issues that the cloud computing researchers have been trying to resolve is the reduction of the carbon emission by the data centers. This paper discusses the modern systems, which are developed for the improvement of energy efficiency in case of large scale cloud computing infrastructures while not compromising the quality of services and performance, by investigating all possible areas in the cloud infrastructure responsible for the considerable quantity of energy consumption. A comparative analysis of different survey papers published in recent times is carried out and their key contributions are also reported. It also discusses the various tools that are employed for the designing of energy-efficient schemes. Based on the recent trends of energy-efficient algorithms, futuristic scope in the domain is also provided for the cloud computing research community.
