A Review on Secure and Energy Efficient Approaches for Green Computing

The technology has advanced so fast and has attracted almost all the business organizations to move in single dimension called cloud. Green Cloud Computing (or Green Computing) is the energy-efficient and environment-friendly form of cloud computing. Cloud computing is a rising trend employing the concept of large data centers but suffering from the concerns such as exorbitant heat emissions, superfluous consumption of energy, release of tremendous amounts of injurious compounds and gases like methane, carbon-dioxide, nitrous oxide etc. that cause green-house effect. By overcoming all of the stated issues of cloud computing by the help of virtualization and energy-efficiency, green computing evolved as a better technology to adopt. In this paper, a review of all the techniques and approaches utilized to implement virtualization, security and energy-efficiency in green computing has been done. Additionally, the comparison of all these techniques is provided for better understanding. Thus, this paper encourages green computing for cloud computing, due to its better performance and security reasons, to be implemented by all the businesses that are planning to migrate to cloud.
