Is vps a CVM? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

No. Vps divides a server into multiple virtual private servers using virtual technology; a CVM is a part of a group of cluster hosts that are similar to independent hosts in cloud computing, and each host in the cluster has an image of the CVM.

Differences in overall performance

The CVM is an operating system at the hardware level, while VPS is at the software level, which consumes system resources. The CVM is faster, more stable and more powerful than the vps host. The CPU and disk performance of the CVM is several times higher than that of the VPS, so it is more suitable for websites with large visits and resources.

Take the comparison between the third generation elastic CVM and vps as an example

1. Storage mode

CVM supports two storage modes: distributed storage and SSD hard disk, and you are free to choose. Vps host each server uses local storage separately, usually sata or sas hard disk to do Raid5 array.

two。 Disk IO performance

Distributed storage of CVM: randomly read 400M/s, randomly write 70m Universe SSD hard disk: randomly read 500M/s, randomly write 400M/s. The vps host is usually 50~150M/s.

3. Heat transfer

The CVM is supported when using distributed storage. The system does not need to restart or shut down, and the network is continuous. The business will not be interrupted and will be completed in about 10 seconds. Vps does not support hot migration.

This is the end of the answer to the question about whether vps is a CVM. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
