Using CloudSim to Model and Simulate Cloud Computing Environment

Cloud computing will be a major technology in the development of the future Internet of Services. Service providers want to remove the bottle neck of the cloud computing system in order to satisfy user requirement. And in order to save energy consumption they also need to apply new energy-efficiency mechanism and observe its effects on a data center. As it is difficult to test new mechanism in real cloud computing environment and researchers often cannot reach the real cloud environment, simulation to model the mechanism and evaluate the results is necessary. Simulating a data center avoids spending time and effort to configure a real testing environment. Moreover, as real machines are not used for testing purposes, their computational power can be allocated to profit-making applications. This paper introduces a simulation framework called CloudSim which provides simulation, power to manage services and modeling of cloud infrastructure. And we have also discussed about how to extend it to simulation your own mechanism in cloud computing.
