At present, all walks of life need to buy computer resources, and cloud computing has also been applied in all walks of life. To some extent, the popularity of cloud computing in all walks of life in the future is inevitable. At present, cloud computing is widely used in manufacturing, e-government, education and scientific research, finance, medicine and medical care, entertainment and games, transportation and logistics, new retail and other fields. Because these industries have high requirements for computer resources, there are a lot of data to be processed. If IT is expensive to purchase IT resources by themselves, many enterprises will choose to use services related to computer resources provided by cloud computing vendors to reduce costs and improve efficiency.
