This article introduces the knowledge of "what's the difference between a CVM and vps". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First of all, let's introduce what a CVM is.

CVM, using hardware virtualization technology in the server cluster, each user monopolizes host resources, and different users will not face preemption of resources; good isolation function ensures that hosts will not affect each other due to host failures of other users It provides independent operating system, underlying RAID protection, built-in protection against ARP spoofing, IP spoofing, distributed deployment to mitigate DDOS attacks, etc. Users can flexibly choose operating systems and software and update and patch them at any time. Built-in KVM (Console) allows you to manage CVMs through the Web page.

VPS: multiple virtual servers are separated by one server virtualization. If you compare VPS to a faucet, the server's computing and storage resources are a water pipe with many faucets on it. You have to pay for renting this faucet, and its water flow is limited. If you want to get more water flow, then you need to rent more faucets, and if all faucets are running, then the water flow of each faucet will be reduced.

CVM: multiple servers are virtualized and many virtual servers are separated. In the host computer under cloud computing, what you get is a faucet with large or small flow, and the server changes from one to a group, just like a water pipe into a large water pipe composed of many water pipes. When you need a larger flow, you can directly control your faucet to increase the flow, and even if all the pipes are running, it will not affect your flow. What's more, the cost you have to pay is no longer the result of renting water pipes, but for the amount of water you need. CVM is better than vps in performance and stability, but they are all virtual machines.
