Energy efficient cloud computing

Abstract

Cloud Computing is a developing technology which is revolutionizing the IT Infrastructure due to its high scalability and flexibility in providing the computing resources as services on demand. Cloud data centres are made up of large servers which consume a great amount of power which will in turn increase the operating costs and the environmental impact in terms of CO2 emissions. Hence, Cloud Computing solutions are extremely effective in terms of processing power and storage but are often criticized for the high amount of energy they require. Therefore, this paper will look at how to model the energy usage of a simple cloud solution, taking into consideration primarily the running of the hardware servers, from the idle to full utilization, as well as the transport of data between servers. An energy saving mechanism named DVFS is used in this paper in order to reduce the energy consumption. Cloudsim toolkit is used to create the cloud data centre and analyze the efficiency of DVFS mechanism.
