A Review on Green Cloud Computing as a Step towards Promoting Sustainable and Eco-Friendly Computational Approach

Green Cloud is an idea that contributes towards faster digital computational unit with low access cost by an eco-friendly means. Green revolution promotes the use of available resources in environment friendly way and Cloud technology offers storage, database, networking, software, analytics and many more services to its customers on Pay-As-You-Go basis. In today’s scenario, technology is moving largely towards cloud. There is a drift of big as well as small businesses on cloud. With this alteration, there arises a need to go green, as there is lot of carbon footprints and emissions with the use of electronic devices like laptops, standalone PCs, servers etc. The focus of green technology is to minimize the computational costs along with saving the substantial energy consumption and effective utilization of such devices. Green Cloud Computing is an approach towards promoting the green concept in cloud technology. This paper highlights the need to switch to green technology and provides various ways by which it can be attained. The emphasis is on the use of Green Cloud with a mention of its architecture and usefulness, which probably would optimize the performance of cloud without harming the environment. The study is based on the work done by various scientists working in data centers concluding that there is a need of getting green with cloud technology.
