Through the cloud computing technology, a network service provider can process tens of millions or even hundreds of millions of information within seconds to achieve the same powerful network service as a super computer. The concept of cloud storage is similar to that of cloud computing, and refers to a system which integrates a large number of storage devices of different types in a network through application software to cooperatively work through functions such as cluster application, a grid technology or a distributed file system, and provides data storage and service access functions to the outside, so that the security of data is ensured, and the storage space is saved.
