Review on Reliability and Energy-Efficiency Issues in Cloud Computing

Abstract

In the current era of information technology, data is increasing exponentially due to the large number of devices in the network. This leads to the rise of a concept called cloud computing, which becomes the need of time and also results in the rise in popularity of cloud computing. It becomes critical to provide on-demand services that adapt to the needs of the customer. Two important factors that trigger cloud computing systems (CCS) are reliability and energy efficiency. This article provides a comprehensive overview of available strategies for ensuring reliability and energy efficiency in cloud computing, combined approaches, the current status, as well as their trade-offs.
