Study on Green Cloud Computing and Environmental Feasibility

Cloud computing is an infrastructural model that is used for enabling convenient, on-demand access to compiled pool of computing resources. Sharing of resources is its primary concept which helps in achieving coherence and economies of scale. Cloud computing is a concept in which multiple users can access the compiled or heaped resources or update their data without purchasing licences for different applications. The main advantage of cloud computing model is that the user can access services based on their requirements irrespective of where the service is being hosted. Cloud computing is an infrastructure that is vastly scalable and cost effective due to which there is an enormous growing demand for it. This has led to a critical issue of increased energy consumption at data centres which are indirectly increasing the operational cost. Due to this, the profit margin of cloud providers has decreased. Another serious issue has emerged due to increased energy consumption is high carbon emission which makes it unsafe for environment. Thus, in this chapter, we will discuss various elements of Clouds that contributes to the entire energy consumption and also explain the roles of cloud users in achieving this goal.
