In this issue, the editor will bring you about the difference between vps and CVM. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

VPS is divided from a server into multiple virtual private servers with a virtual machine. The CVM is an independent host similar to VPS, which is separated from the cloud computing cluster.

Vps virtual private server, which is virtual server software (such as Hyper-v, VMware, XenServer, Virtuozzo, etc.) to create multiple small servers isolated from each other on a physical server. These small servers have their own operating system, and their operation and management are exactly the same as stand-alone servers.

CVM integrates the IT infrastructure capabilities of computing, storage and network resources to provide on-demand and on-demand server rental services based on cloud computing model. CVM is a virtual part of multiple independent hosts on a cluster composed of several servers, which has the characteristics of high reliability and strong flexibility.

Performance / price ratio

If a server is divided into 5 vps hosts, the memory and CPU supporting virtual machines account for about 35% of the parent server. The remaining resources are allocated to five virtual machines, which consumes more resources and has a great impact on performance.

CVM is a cloud computing platform composed of hardware isolation and a large number of servers. The less resources are consumed, these are hardware isolation. It is also much better than vps in terms of resource utilization and scalability.

II. Security

VPS if there is a problem with the parent server, it means that all the virtual space inside is also out of order. On the other hand, if there is a problem with a server and an image file in the CVM cluster, it can be automatically switched to a normal node without any interruption.

III. Anti-attack

Generally speaking, the anti-attack ability of CVM is higher than that of vps. At present, many cloud service providers also provide ddos high defense. When the service is unavailable after the CVM and vps are attacked by high traffic Ddos/CC, users can configure ddos high defense to clean and filter malicious attack traffic to ensure the stability and reliability of the host.

This is what is the difference between vps and CVM shared by Xiaobian. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
