In general, talking about grid computing, everyone will think of the rage of the search for extraterrestrial year project, that is in the machine by installing a screen saver software that can take advantage of all leisure time when everyones PC computing power to participate in the search alien calculations. This also illustrates the grid goal is to want as much as possible use of resources. It is through specific grid software, a huge project broken down into numerous independent of each other, less-related sub-tasks, and then calculated by the various computing nodes. It should be said from that point, job scheduling is a core value of grid computing. Turning now to cloud computing, we can immediately think of the Internet data center services, packaged into a variety of resources available outside. In general, though, like grid computing, cloud computing, like all of the resources to build into a huge pool of resources, but it provides a cloud computing out of resources in order to complete a specific task. For example, a user may need to apply a certain amount from the resource pool of resources to deploy their applications, rather than its mandate will be submitted to the entire grid to complete.
