Energy efficient approach to Cloud Computing

Abstract

Cloud computing is an emerging area within the field of information technology (IT).It is turning upside down the way we realize computation by enabling the use of storage, processing, or higher level elements such as operating systems or software applications, not by owning them and having them installed on computers that we own - but rather to use these resources simply as a service. The term cloud computing causes confusion due to the multiple aspects of service that it may include. From a generic point of view, it could be said that cloud computing is a kind of computing where scalable, adaptable, and elastic IT capabilities are provided as a service to multiple users. In a pure cloud computing model, this means having all the software and data hosted on a server or a pool of servers, and accessing them through the internet without the need for very much (if any) local hard disk, memory, or processor capacity, allowing the use of very light weight client computers by the end user. Key Words: Cloud Computing, DVFS, Cloud, VM Consolidation, Power consumption, energy efficiency.
