The distributed computing technology proposed by Google makes it easy for developers to develop global application services, and cloud computing technology automates the management of communication, task allocation, and distributed storage among a large number of standardized (heterogeneous) computers. 　　The cloud comes from a decentralized, parallel operation, but better than the grid. Data computing cloud technology can be considered as a sub-set of grid technology, both of which are designed to hide the complexity of the system, so that users need to use it without knowing how the system works inside. The parties follow up with Google to promote cloud services, but the definition is different ...

In general, San virtualization products are more prevalent than NAS virtualization products. NAS Virtualization products provide a "global namespace" feature, usually in a very large data sharing access environment to fully benefit, the majority of users have limited environmental complexity, and do not need to choose such products to solve the data sharing access path/directory too complex problems. In contrast, San virtualization products can be useful and more widely available even in small environments with only a 2~3 disk array and only hundreds of gigabytes of data. Current status of NAS virtualization products ...
