Cloud storage is in the cloud (Cloud Computing) is a new concept on the extension and development of it, by means of cluster applications, grid technology and distributed file system and other functions, will be a large variety of network storage devices of different types of set up through the application of software collaborative work, work together to provide a system function data storage and business access to foreign. When the core system operation and processing of cloud computing is a large amounts of data storage and management, cloud computing systems will need to configure a massive storage devices, so the cloud computing system is transformed into a cloud storage system, so the cloud storage is a data storage and management as the core of the cloud computing system.
When we use a separate storage device, we must be very clear the storage device is what type, what interface and protocol, must know clearly how many blocks of disk storage system, which is what type, large capacity, must be clear between a storage device and a server using the connection cable, what kind of. In order to ensure the continuity of data security and business, we also need to establish a data backup system and disaster recovery system. In addition, the storage device regularly in condition monitoring, maintenance, hardware and software updating and upgrading is necessary.
If the cloud storage, the above all the user do not need. All equipment cloud storage system is completely transparent to the user, any place any authorized user can access through a cable connected with the cloud storage, data access on cloud storage.
Cloud storage in cloud computing (Cloud Computing) is a new concept on the extension and development. Cloud computing is a distributed processing (Distributed Computing), parallel processing (Parallel Computing) and grid computing (Grid Computing) development, through the network will be huge computing program automatically split into numerous smaller subroutine, the calculation and analysis of the processing results back to the user pay huge system consisting of multiple server the. Through the cloud computing technology, network service providers within seconds, with tens of millions or even billions of information, achieve and "super computer" equally powerful network service.
The concept of cloud computing cloud storage is similar, it is through the cluster applications, grid technology and distributed file system and other functions, will be a large variety of network storage devices of different types of set up through the application of software collaborative work, a system to provide external data storage and service access function. If this interpretation is difficult to understand, the structure that we can borrow the wide area network and the Internet to explain the cloud storage.
