A Comparative Study of Cloud Computing Over Grid Computing
Cloud computing is the most advanced technology that has been launched on the network world. Clouds are considered as a new generation of grid computing. Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like electricity grid) over a network .This paper focuses on comparing cloud computing to previous generations such as grid computing, by reviewing some security and policy issues in cloud and grid computing. At the end, this paper describes the similarities and differences between the grid and cloud approaches.
