When cloud computing has just been known, most people hear about public clouds. This is mainly because the public cloud service providers are some of the industry's big companies, such as Google, Amazon and so on. By the time people actually started to let cloud computing fall to the ground, the focus was on private clouds. This is because the data security, controllability and other aspects of consideration, the enterprise is more willing to choose private cloud. 　　In view of this, it is necessary to understand how to deploy a private cloud. In general, private cloud construction involves implementing virtualization, deploying automated tools, developing new processes, and managing systems, among others, although someone ...
