Energy-aware of cloud computing
Abstract: Cloud computing is an emerging model of Business Computing, it distributes computing tasks in a large amount of computer resources pool, so that all applications can access computing power, storage space and a variety of software service according to the needs of users. Cloud computing will all the computing resources together, and realized by software automatic control, without human involvement. This makes the application providers need not to worry about trivial details, and to be more focused on pay more attention to their own business. Furthermore, it is conducive to innovation and cost reduction. Cloud computing technology allows inpiduals and businesses to extremely high computational power available at very low cost.
This paper introduces the definition and characteristics of cloud computing first. Then focuses on energy consumption of cloud computing and energy-aware algorithms for cloud computing. Finally, DVFS and threshold-based algorithm are studied on platform of cloud computing. The results show that energy-aware algorithms can reduce the energy consumption of cloud computing which benefit to the environment.
Keywords: Cloud computing ; Energy-aware algorithm ; CPU utility
