To understand cloud services, you must first understand the fundamentals of cloud computing. Cloud computing: Enterprise data centers run more like the Internet by making calculations on a large number of distributed computers rather than on local computers or remote servers. 　　This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed. This type of service is to mobilize the various resources in the network to serve the users. (personally think a bit like BT). 　　Unity is strength! 　　This service will be the mainstream of the future. According to the Market research institute IDC said, ...
