Application hosting for business, consumers and scientific domains is made possible with cloud computing. However, the data centres used for this purpose consume large amount of energy. This increases the operational cost and contribute carbon footprint affecting the environment. With increasing energy scarcities and global climate changes, it is essential to control power consumption. This paper presents a green cloud computing solution that addresses the issues of operational cost reduction and decreasing the carbon footprint and its impact on the environment. For this purpose we use data mining tools and auto-scaling with constraint satisfaction problems (CSP). Keywords: Green cloud computing, environmental protection, operational cost, 1. INTRODUCTION Cloud computing technology is a dynamic domain in information and communication technology. It is a distributed parallel computing technology that offers reliability, scalability, low cost and high performance. The factors such as improvement in energy efficacy, carbon footprint and e-waste lessening enables the development of green cloud computing technology. Large amount of servers and data centres work towards providing pay- per-use services to the consumers. These resources occupy huge area and require large amount of power. There are mainly four types of cloud-computing architecture namely – External or public architecture – Where an offsite provider maintains the resources on pay per-use basis. Internal or private architecture – A cloud infrastructure that works solely for a specific organization.
