What this article shares with you is about the difference of vps on CVM. The editor thinks it is very practical, so I share it with you. I hope you can learn something after reading this article. Without saying much, let's take a look at it.

Storage mode

Vps mainly uses the local hard disk of the server for storage, and there is only one copy of data, which needs to be backed up manually to ensure the security of the data. CVM is mainly network distributed cluster storage, and multiple copies of data will be written in real time, which is more secure and has advantages for data backup.

Capacity expansion

Because the vps host is split from the server, different users use different resources, so when users need to expand their capacity, there will be certain restrictions. When the utilization of mother machine resources reaches the highest level, the further expansion will be affected.

The most important feature of CVM lies in flexible expansion, dynamic load balancing and so on. When network bandwidth, memory and hard disk are insufficient, it can be flexibly expanded and configured without limitation.

Stability.

Because the vps host seldom supports hot migration and the parent machine fails, the vps host will also have problems.

On the other hand, the CVM is mainly on the scale server cluster, and there will be an image of the CVM on each server, so if there is a problem with a CVM, it will be automatically migrated to other CVMs to continue to run. Therefore, the stability is better.

Anti-aggression

At present, many cloud service providers can provide application firewall and ddos high-defense server, but vps hosts rarely have such defense capabilities, so their defense capabilities are incomparable.

These are the differences between CVM vps. 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.
