一、Definition of Cloud Computing(云计算的定义)

Cloud computing is a computing method based on the Internet, by this way, the sharing

of hardware resources and information can be

provided to computers and other devices

Cloud computing is the development of distributed computing, parallel processing, and grid computing, which represents an emerging business computing model

云计算(cloud computing),是一种基于互联网的计算方式,通过这种方式,共享的软硬件资源和信息可以按需提供给计算机和其他设备
