Executive Summary

Cloud computing has emerged as a new paradigm of computing and gains increasing attention from both academic and business community. Its utility-based usage model allows users to pay per use, similar to other public utility such as electricity, with relatively low investment on the end devices that access the cloud computing resources. From the environmental perspective this new computing model is already a great improvement since the computing resources are shared among all users and provisioned on-demand. However, data centers hosting Cloud applications consume huge amounts of electrical energy, contributing to high operational costs and carbon footprints to the environment. Therefore, the authors need Green Cloud computing solutions that can not only minimize operational costs but also reduce the environmental impact.
