This article introduces the knowledge of "how VPS CVM works". In the operation of actual cases, many people will encounter such a dilemma. Next, 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!

What is VPS?

Start by looking at VPS and how it works. A virtual private server (VPS) is a virtual machine (VM) used as a server. A virtual machine refers to a computer system that actually exists on another real computer. The computer is designed to present resources such as disk, memory and CPU to the operating system. 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. With the popularity of the idea of VPS, CPU design began to combine some features to improve virtual machines so that they can run with better performance. This performance improvement, coupled with the energy efficiency of modern computers, allows many old computers to be virtualized to fewer new computers, thereby reducing the electricity bills of many companies in the process.

In order to distinguish between a hardware computer and a virtual computer, a hardware computer is often called a host, and the virtual machine running on it is a guest account. One of the limitations of these virtual machines is that they rely on the host to operate, and if anything goes wrong with the host, all guests will stop. The development of the VPS CVM concept is designed to provide a way for virtual private servers to run without this restriction.

What is a VPS CVM?

At its basic level, the VPS cloud consists of multiple computers that work together to host many guest virtual machines. 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 guest virtual machine 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 data security for guest virtual machines.

This is the end of "how VPS CVM works". Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
