A survey of computing strategies for green cloud

Cloud computing is the much sought after technology as it solves large computational problems by using various resources and also offers many other services through the internet. The computational offloading and the increased demand for timely and appropriate response for real time applications has resulted in the need to improve the performance of the cloud. In addition to this, the tremendous growth in the data and in requests has resulted in the deployment of large number of data centres throughout the world. This in turn increases the economic and the environmental cost which is due to the high consumption of energy by the data centres. Further the emission of CO2 and other gases has paved way for the growth of carbon footprint and hence the greenhouse effect. These form the driving factors for green technology. So energy efficient solutions which involves optimal utilization of the available resources is a necessity. This paper provides an overview of the cloud system, the metrics which are mandatory to have a green flavor of cloud computing and the strategies that are currently used.
