摘要：Energy efficiency in all aspects of human life has become a major concern, due to its significant environmental impact as well as its economic importance. Information and Communication Technology (ICT ) plays a dual role in this; not only does it constitute a major consumer itself (estimated 2 - 10% of the globa l consumption), but is also ex pected to enable global energy efficiency through new technologies tightly dependent on networks (smart grid, smart homes, cloud computing etc.). To this purpose, this research - work studies the problem of sustainable use of electric energy in cloud computing. As this subject has recently become very active in the research community, there is parallel research towards se veral research directions. In this work, the problem is being examined from its foundations and a solid analytical approach is presented. Cloud computing promises a new era of service delivery and deployment in such a way that every person can access any k ind of services like storage, application, operating system and so on from anywhere any time using any device having internet connection. Cloud computing opens new possibilities approaching sustainable solutions to deploy and advance their services upon th at platform. Sustainability of Cloud computing is to be addressed in terms of environmental and economic effects. In recent years, there have been two major trends in the ICT industry: green computing and cloud computing. Green computing implies that the I CT industry has become a significant energy consumer and consequently, a major source of CO2 emissions. Cloud computing makes it possible to purchase IT resources as a service without upfront costs. In this research, the combination of these two trends, gr een cloud computing, will first be evaluated based on existing research findings, which indicate that private clouds are the most green option to offer services . Case studies of state - of - the - art companies offering green hosting services are presented and i ncentives affecting their energy - efficiency development are analyzed. The results reveal that currently there is no demand in the market for green hosting services, because the only incentive for companies is low costs. Presently, massive energy consumptio n in cloud data center tends to be an escalating threat to the environment. In this research work we explore the energy efficient approaches inside data centres from the site and IT infrastructure perspective incorporating Cloud networking from the access network technologies and network equipment point of view to give a comprehensive prospect toward achieving energy efficiency of Cloud computing. Traditional and Cloud data centres would by compared to figure out which one is more recommended to be deployed . Virtualization as heart of energy efficient Cloud computing that can integrates some technologies like consolidation and resource utilization has been introduced to prepare a background for implementation part. Finally approaches for Cloud computing data centres at operating system and especially data centre level are presented and Green Cloud architecture as the most suitable green approach is described in details. In the experiment segment we modelled and simulated system and studied the behaviour in te rms of cost and performance and energy consumption to reach a most appropriate solution
