  Introduction Cloud Computing hasbecome another buzzword after Web 2.0. On Cloud Computing is not a completely new concept; it has intricate connection to the relatively new but thirteen- year established Grid Computing paradigm, and other relevant technologies such as utility computing, cluster computing, and distributed systems in general. This paper strives to compare and contrast Cloud Computing with Grid Computing from various angles and give insights into the essential characteristics of both. 2

  Cluster Computing  Acluster is a collection of parallel or distributed computers which are interconnected among themselves using high-speed networks, such as gigabit Ethernet, SCI, Myrinet and Infiniband.  Clusters are used mainly for high availability, load-balancing and for compute purpose.  When multiple computers are linked together in a cluster, they share computational workload as a single virtual computer. 3

  Grid Computing  Gridcomputing combines computers from multiple administrative domains to reach a common goal, to solve a single task, and may then disappear just as quickly.  Grid as a type of parallel and distributed system that enables the sharing, selection, and aggregation of geographically distributed autonomous resources dynamically at runtime depending on their availability, capability, performance, cost, and users quality-of- service requirements.  Grid computing is extended of Cluster computing. 4 •PC1 •PC2 •PC300 •PC1 •PC2 •PC20 •PC1 •PC2 •PC50 •PC1 •PC2 •PC100 CLUSTER 1 CLUSTER 2 CLUSTER 4 CLUSTER 3

  Cloud Computing  Cloudcomputing refers to both the applications delivered as services over the Internet and the hardware and system software in the data centers that provide those services.  Cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreement.  Extend of Grid Computing. 5

  Services of Cloud Cloudcomputing provides basically three kinds of service:  SaaS: Software as a Service. Example service providers are Salesforce, Customer Relationships Management(CRM) system and Google Apps, MS Office Online.  PaaS: Platform as a Service. Some example service providers are Google’s App Engine , Microsoft Azure , RightScale and SalesForce .  IaaS: Infrastructure as a Service. Some of the IaaS providers are AWS, Eucalyptus, Open Stack, GoGrid and Flexiscale. 6

  Conclusion We have presenteda detailed comparison on the three computing models, cluster, grid and cloud computing Grid and cloud computing appears to be a promising model especially focusing on standardizing APIs, security, interoperability, new business models, and dynamic pricing systems for complex services. Hence there is a scope for further research in these areas. 14
