With the advent of the cloud era, more targeted products and services have gradually evolved, Public cloud, private cloud, hybrid cloud 。 What is the difference between the three? Let's use an analogy to illustrate.
For example, when we come to a city and need to sleep, we have to go to a hotel. The hotel provides us with room rest, which is called public cloud service.
After a while, I thought the city was good. I bought a house for myself to rest or do other things. This is a private cloud service.
One day, many relatives and friends came to my home and couldn't stay. Some people lived at home and some people lived in hotels. This is hybrid cloud.
The concept of the cloud is that we put the services of houses and hotels on the top of a cloud, follow wherever we go, and provide services to us in a timely manner as long as we need them.
characteristic:
Public Cloud : Low cost, very good scalability. The disadvantages are lack of control over cloud resources, security of confidential data, network performance and matching problems.
Private Cloud : It can effectively control data confidentiality, data security, and service quality. Its biggest feature is security and privatization, which is the basis of customized solutions. It is a very good choice for enterprises that have requirements for data security and stability.
Hybrid cloud : It integrates the convenience of public cloud and the security and stability of private cloud. For security reasons, enterprises want to store data on the private cloud, and also want to use the free resources of the public cloud. Therefore, they will reasonably mix the public cloud and the private cloud, and place sensitive data or critical workload on the private cloud, while ordinary work or work that needs to be extended will be placed on the public cloud, To achieve the goal of safety and saving money.
