Cloud Computing: how is Cloud Computing classified

What is cloud computing?

Cloud computing (cloud computing) is a kind of distributed computing, which refers to the decomposition of huge data processing programs into countless Mini Program through the network "cloud", and then through the system composed of multiple servers to process and analyze these Mini Program results and return them to users. In the early days of cloud computing, to put it simply, it was simple distributed computing, solving task distribution, and merging computing results. Therefore, cloud computing is also called grid computing. Through this technology, tens of thousands of data can be processed in a very short time (a few seconds), thus achieving a powerful network service. [1]

The cloud service mentioned at this stage is not only a kind of distributed computing, but also the result of the mixed evolution and leap of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup clutter and virtualization.

Cloud computing classification:

Private cloud

It is usually owned by enterprises themselves, and specific CVM functions are not directly open to the public.

Public cloud

Enterprises use the external cloud to serve users outside the organization, that is, enterprises / organizations outsource cloud servers to public cloud providers, which can reduce the cost of building cloud computing facilities.

Hybrid cloud

Hybrid applications that include private and public clouds ensure control of parts such as sensitive data through private clouds while reducing costs through outsourcing.
