1 Grid concept "Grid" The noun earliest appeared in the mid-1990s, which was used to represent a distributed computing infrastructure suitable for senior science and engineering research [1]. Grid as a data and computing resource management will provide basic support for global business, governments, research, science and enterprises [2]. Through the grid, we can share resources between multiple dynamic virtual organizations to solve problems.
2 Grid Feature Grid As an infrastructure that provides dynamic resource sharing and extensive work, it has determined some of its characteristics in addition to some of the same features with the past network and distributed systems, and these Features have also determined that grid security is destined to have many places to contact and distinguish between traditional security. 2.1 Distribution and previous distributed systems, the grid will have the ability to manage distributed resources, complete distributed collaborative computing, and the distribution performance of the grid requires more extensive. The resources on the grid will no longer be limited to the same organization, more of all resources on the Internet; the collaborative computing of grid support In addition to the calculation of collaboration completion and distribution, there is also a remote use of resources. This distribution will be more dependent on the transmission of networks and using Grid Service, Web Service and other collaboration tools. 2.2 Dynamicity and any of the previous systems are that the grid must support the dynamic adjustment and planning of resources and services. The exit of resources and services cannot affect the normal operation of the system, and their access must be immediately discovered and available. 2.3 Isomeric Taking into account the relationship between economics, commercial interests, competition, the system in future grid environments is inevitably a variety of heterogeneous systems, or under different network architectures, or use different operating platforms. The grid must be able to support communication and interaction of these heterogeneous systems. 2.4 Virtualization of Virtualized Grid Services provides a ability to seamlessly map generic semantic behavior to local platforms. Virtualization allows us to across platforms for transparent consistency, and map multiple logical resource instances to the same physical resource. [3] 2.5 Intelligent grids will be more intelligent than now, it will be more robust as the computational environment changes, will be more robust, and the search for resources will be more user Actual demand. 2.6 The resources in the future grid will be more than just computer hardware, but also some special equipment, valuable instruments, and even household appliances. The tools used by users to access grid services are no longer limited to computers, mobile phones, handheld, and other mobile devices will join this ranks. Tasks with large computing power requirements can also be solved using the computing power provided by the grid in the case where there is no ability to solve it and will not be able to fight back to the previous.
