An Extension and Improvement of the CloudSim Simulator

Cloud computing has become a significant technology trend. With the cloud computing technology, users use a variety of devices to access programs, storage, and application development platforms over the Internet, via services offered by cloud computing providers. Advantages of the cloud computing technology include cost savings and high availability. Access to the infrastructure in Cloud Computing incurs payments. To design and develop Cloud technologies focus on defining novel methods, policies and mechanisms for efficiently managing Cloud infrastructures. To test these newly developed methods and policies, researchers need tools that allow them to evaluate the hypothesis prior to real deployment in an environment where one can reproduce tests free of cost.
