Cloud Computing makes the dream of computing real as a tool and in the form of service. This INTERNET-based ongoing technology which has brought flexibility, capacity and power of processing has realized Service- oriented idea and has created a new ecosystem in the computing world with its great power and Benefits. Cloud capabilities have been able to move IT industry one step forward. Nowadays, large and Famous enterprise has resorted to cloud computing and have transferred their processing and storage. Due to popularity and progress of cloud in different organizations, cloud performance evaluation is of special importance and this evaluation can help users make right decisions. In this paper, we provide an overall perspective on cloud evaluation criteria and highlight it with help of simulation. For this purpose, we present different major factors in cloud computing performance and we analyze and evaluate cloud performance in various scenarios considering these factors.
