A Review on Power Saving & Security Mechanisms in Cloud Computing

Cloud Computing is a distributed technology that influences sophisticated technology innovations which are highly scalable & resilient and can be used in a variety of powerful ways. The primary focus of the Cloud is the delivery of remote computing resources over the Internet in an affordable and reliable manner. The on-demand nature of cloud services result in the need of energy efficient servers which can satisfy the performance expectations of a cloud user. Servers catering to a constantly increasing user base find it difficult to conserve power due to the random and on-demand nature of the cloud. While cloud computing puts forth an economic ease for providers as well as users, it poses striking security challenges to preserve user data and maintain their trust over this technology. In spite of significant research and development, loopholes still exist in the polices of Cloud Computing. The fundamental aim of this paper is to explore various power saving and security mechanisms for Cloud Computing. Several power saving polices are studied and their efficiency is compared. Different security mechanisms were taken into consideration and discussed. Increasing need for on demand computing services on various platforms brings a new level of attention to energy efficiency and security in the world of the cloud.
