Compared to cloud computing systems, cloud storage can be considered a cloud computing system configured with large storage space.
Cloud computing is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grids Computing), which automatically splits large computational handlers into countless smaller subroutines through the network, A large system of multiple servers is calculated and analyzed to pass the processing results back to the user. With cloud computing technology, Web service providers can handle tens of millions of billions of dollars of information in a matter of seconds to achieve the same powerful network services as supercomputers. The goal of the cloud computing system is to run on the PC, or stand-alone, personalized operations on a single server migrate to a large number of server "Clouds", which is responsible for processing the user's request and outputting the results, which is a system centered on data operation and processing.
Cloud storage is a new concept that extends and develops in the concept of cloud computing (cloud computing), which means that a large number of different types of storage devices in the network can be assembled together through application software through the functions of cluster application, grid technology or Distributed File system, A system that provides data storage and business access functions together externally. When the core of cloud computing system operation and processing is large amount of data storage and management, cloud computing system needs to configure a large number of storage devices, then cloud computing system is transformed into a cloud storage system, so cloud storage is a data storage and management as the core cloud computing system.
