Abstract
Cloud computing is the most recent announced technology that has been launched on the network world.
Clouds are considered as a new generation of Grid computing. Clouds consist of data centres which are
owned by the same institute. The homogeneity within each data centre in the infrastructure is the main
feature for the cloud computing compared to grid computing. This paper provides a definition for the
cloud, it discusses many aspects of Cloud Computing, and describes architectures for the cloud (by looking
at Amazon’s application (GrepTheWeb)) and how its cost definition differs from that of Grid computing.
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.
