Cloud computing is the internet based computing where sources are accessed via online. These services have the ability to extend the provisioning of resources based on users demand. The user applications are submitted to the virtual machines for processing. So the mapping of user tasks to virtual machines plays a major role in efficient provisioning of resources. The task scheduling problem can't be solved in polynomial time. So for solving this kind of problem, the heuristics algorithms like particle swarm optimization are used.
