What this article shares with you is about the meaning of the CVM. The editor thinks it is very practical, so I share it with you to learn. I hope you can learn something after reading this article. Let's take a look at it with the editor.

The concept of CVM is relatively abstract. In order to facilitate your understanding, we don't talk about definition, but use some metaphors to explain it in a popular way.

The host company makes its hardware and network lines into a "cloud" and then provides some network interface API to the "cloud" for customers to use. At this point, each customer no longer shares a particular server, but all the servers in the cloud.

For example, suppose you want to back up your local files to the Internet, you can use a shared host to transfer the files to a certain server, or you can use a cloud server to transfer them to the cloud through some form of interface. In other words, the shared host user directly faces the specific server, while the CVM user directly faces the network interface and cannot see the inside of the server.

A popular analogy is that you can rent a safe number "6886" from the bank (shared mainframe), or you can give your valuables directly to the custodian company (cloud host) and leave them to take care of them.

1. Low cost

CVM leasing does not require a deposit, and the capacity is expanded flexibly on demand. Users only need to pay for the storage, computing and resources used, which will not cause a waste of resources. Because services can be distributed to multiple servers, they can make full use of resources and reduce hardware, power, and maintenance costs. Charging according to usage is particularly beneficial to small websites.

two。 High reliability

Because cloud services are distributed in multiple servers or even multiple data centers in multiple regions, it is not easy to have complete downtime. Even if one fails, it will automatically switch to a normal node, which has strong disaster tolerance and long-term online service.

3. Good expansibility

The basic feature of the CVM is the distributed architecture, so you can easily increase the server, multiply the service capacity, online upgrade is convenient and fast, and will not affect the website business.

This is what the CVM means. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
