Cloud computing is a boon for almost every sector as it reduces the overall expenditure by making IT infrastructure, services and platform on \"On-demand\" basis. The \"Pay-as-you-go\" policy of cloud technology enables the users to use and pay for the services and computing infrastructure only when they need it without worrying about the installation and underlying hardware or software infrastructure. Data centers are located at different locations and provide services to the users in their closest proximity. As the user has to pay for the service utilization, so selection of data center plays an important role for maximum resource utilization at minimum expenditure and best response time.
