The most common similarity between cloud computing and network computing is in virtual computing and sharing resources. is to make the resource utilization more reasonable, the Internet resources can be collected and provided to users to enjoy. If from a different point of view can be divided into 2 aspects:
1. Cloud computing is a business-style model that is not obvious and is available to organizations for organizational operations (collaborative) dependencies, performance assurance and bandwidth assurance.
2. Cloud computing to meet the needs of users. Have the ability to deal with the uncertainty and calculate, the semantic processing, the public communication and so on. Also need to interact with the user; The Scientific computing task is oriented by grid computing, and its input and output are in accordance with the required requirements, there is no person's active participation.
In general, cloud computing is different from grid computing applications, with its potential in two different areas of scientific computing and service users.
