A cloud computing is a fast growing area in computing research and industry today. Three main services provided by the cloud are Infrastructure-as-a-Service (IaaS), Software-as-a-Service (SaaS) and Platform-as-a-Service (PaaS). Private cloud is restricted to a particular organization and data security risks are less compared to the public cloud. Hence, private cloud is built by exploiting the commodity machines within the organization and the important data is stored in it. It is found from literature that scheduling refers to the set of policies to control the order of work to be performed by a computer system.
