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

When in use, there is no difference between VPS and CVM in terms of management. From the operating system's point of view, the VPS server and the CVM are the same. As a result, most of the guidelines and tutorials for configuring a CVM are equally applicable when using VPS.

VPS Virtual Private Server

Is a virtual machine (VM) used as a server. A virtual machine refers to a computer system that actually exists on another real computer. As computers become more powerful and there are more and more RAM and disks available, software is created to simulate real computers using RAM, disks, and various parts of the processor in order to run a normal operating system.

A special software called the hypervisor is used to manage the operation of the virtual machine on the computer. The hypervisor isolates the RAM of the computer and organizes the processing of various virtual machine software on the CPU. The vps virtual machine running on the hardware computer is the guest account. They rely on the host to operate, and if anything goes wrong with the host, all vps hosts will stop.

How CVM works

In fact, a cloud server consists of multiple computers that work together. Some computers run hypervisor software and are responsible for providing guests with CPU and RAM resources. Other computers, called SAN, provide storage for the data of various guests. The other computer controls the entire cloud computing function, assigns hypervisors to run virtual machines, defines their disks on the storage SAN, and ensures that the virtual machines are linked to their relevant data.

One of the biggest reasons for server downtime is hardware failure. Separating the storage of the virtual machine from the host can avoid long downtime. If the hypervisor server encounters a hardware failure, you can move the cloud server to another hypervisor server to run. In a similar manner, redundancy in storage and control servers means that a single hardware failure does not stop cloud computing and ensures the data security of virtual machines.

The benefits of using a CVM are transparent when running the operating system, but it also provides users with additional features of resistance to hardware failures, thus avoiding long downtime. The CVM can also fully meet the needs of users by increasing or decreasing the resources allocated by users.

These are the differences between vps and CVM. 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.
