What is the difference between vps and CVM? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

For most novice users, they may not be able to distinguish or understand the difference between vps and CVM. Here's how they differ.

Vps host

It is virtual server software that creates multiple independent small servers on a single physical server. These small servers originally have an independent operating system, and their operation rights and methods are the same as those of independent servers, but their configuration and performance are limited (multiple vps can be opened on one server, depending on the settings of space vendors), and multiple users share the hardware of one server.

CVM

It can also be called a cloud host, which integrates IT infrastructure capacity rental services for computing, storage and network resources, and on-demand and paid server rental services based on cloud computing model. CVM is a cluster composed of multiple servers, in which multiple parts similar to independent servers are virtualized, with the characteristics of high reliability and flexibility.

Differences in infrastructure

The performance of VPS is limited by its own physical server. If there is a problem with the physical server, the VPS will go wrong, and the website will be affected. The CVM is built on the cluster server, and the normal operation of the CVM will not be affected if there is a problem with one server.

The difference between upgrade methods

CVM lease is virtualized in the network, so upgrading is very convenient, such as upgrading hard disk, bandwidth, CPU and other configurations, and can be completed automatically within a few minutes online. Due to the limitation of the parent machine, the upgrade capacity of VPS is limited and takes longer.

Support for mirroring and private network

CVM natively supports private network transmission, and the speed is extremely fast, which is conducive to load balancing, and can also quickly clone multiple system images. Due to the difference of architecture, it is difficult for VPS to support private network and does not support custom images.

After reading the above, have you mastered the different methods of vps and CVM? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
