分析和优化技术可持续利用电能的绿色云计算

文摘

能源效率在人类生活的各个方面已成为主要问题,由于其显著的环境影响以及其经济的重要性。信息和通信技术(ICT)在这扮演双重角色;它不仅构成主要消费者本身(估计2 - 10%的全球消费),但也将使全球能源效率通过新技术紧密依赖网络(智能电网、智能家居、云计算等)。这个目的,这个研究工作研究可持续发展问题在云计算中使用电能。作为这个问题最近成为研究非常活跃的社区,有平行研究对几个研究方向。在这部作品中,问题是研究的基础,提出了一种可靠的分析方法。云计算的承诺的服务交付和部署一个新时代,每个人都可以访问任何类型的服务,如存储、应用程序、操作系统等在任何地方任何时间使用任何有网络连接的设备。云计算将打开新的可能性接近可持续的解决方案部署和推进他们的服务平台。云计算的可持续性是解决环境和经济方面的影响。近年来,已经有两个主要的ICT行业趋势:绿色计算和云计算。 Green computing implies that the ICT 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, green 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 incentives 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 consumption 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 terms of cost and performance and energy consumption to reach a most appropriate solution.
