In this issue, the editor will bring you the difference between cloud server and virtual host and vps. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

For newcomers who have just come into contact with space products, the concepts of cloud servers, virtual hosts and vps may not be very clear and abstract. Here, let's introduce them respectively.

In terms of price, virtual hosts are relatively cheap, while cloud servers and vps are relatively expensive. In terms of performance, cloud servers are the best, followed by vps, and virtual hosts have more limitations.

Virtual host

It divides a real physical server into multiple logical storage units, each of which has no physical entity, but each logical storage unit can work on the network like a real physical host. Each virtual space has its own domain name and complete Internet service function, and each user has its own part of system resources (IP address, storage space, memory, CPU, etc.).

Virtual hosts are independent of each other, running different server programs opened for multiple users on the same hardware and the same operating system, which can not interfere with each other. At the same time, the disadvantage of the virtual host is also obvious, if this real physical host fails, then all the above websites are inaccessible.

CVM

It integrates three services, such as CPU, storage and network bandwidth, through a unified platform, pay-on-demand services. It effectively solves the shortcomings such as high rental price of traditional host, uneven service and so on.

The CVM can really get the root permission, and users can reinstall and upgrade the operating system. At the same time, multi-node deployment, zero maintenance, easy expansion, auto scaling, non-downtime, etc., the most important thing is that they can pay on demand, and a month or a year can constitute a service.

Vps host

The full name is virtual private server, which uses virtual server software to create multiple small servers isolated from each other on a physical server. These small servers are called VPS, they have their own operating system, and they run and manage exactly the same as stand-alone servers.

The advantage of VPS is that it can ensure that all resources are exclusive to users and divide a server into multiple virtual dedicated servers. Each VPS can be assigned an independent public network IP address, independent operating system, independent super-large space, independent memory, independent CPU resources, independent execution programs and independent system configuration, etc. You can install your own program and restart the server separately.

The deficiency of VPS server rental is that the same physical server, different VPS will affect each other, the performance is limited by the configuration of a single server, and there is no permission of root or Super Admin operating system.

The above is the difference between CVM and virtual host and vps 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.
