What does the grid length mean?

Grid is a mechanism to integrate or enjoy various geographically distributed resources (including computer systems, storage systems, communication systems, files, databases, programs, etc.). ), so as to make it an organic whole, to complete a variety of required tasks.

The word Grid comes from PowerGrid. The purpose of building a grid is to combine hundreds of millions of computers, memories, valuable devices and databases distributed on the Internet to form a virtual and unprecedented powerful supercomputer, which can meet the growing demand for computing and storage and make the information world an organic whole.

Advantages of grid 1, resource sharing, eliminating resource islands: grid can provide resource sharing, eliminate information islands, and realize the interconnection of applications. Grid is different from computer network. Computer network realizes a kind of hardware connection, while grid can realize application connection.

2. Collaborative work: The second feature of the grid is collaborative work, and many grid nodes can handle a project at the same time.

3. Universal open standards, decentralized control and extraordinary quality of service: this is the latest grid checking standard proposed by Ian Foster. Grid is based on international open technical standards, which is different from the software products introduced by many industries, departments or companies in the past.

4. Dynamic function and high scalability: Grid can provide dynamic services and adapt to changes. At the same time, the grid is not restrictive, and it achieves a high degree of scalability.
