Today, I will talk to you about the difference between CVM and vps. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something from this article.

Vps and CVM are products that are often compared together. Here we analyze the differences, advantages and disadvantages of the two, so as to facilitate you to make an appropriate choice when purchasing.

CVM

Advantages: moderate price, flexible use, high availability, single or multiple physical offline will not have much impact on the entire service. Cons: performance is a little lower than that of stand-alone servers.

Vps host

Advantages: the price is cheaper. Disadvantages: low performance, low stability, in addition to its physical machine problems will be affected, virtualization technology problems will also be affected.

The difference between VPS and CVM

1. Virtualization technologies are different

VPS and CVM are virtual host products generated by virtualization technology. The difference is that VPS uses virtualization technology to split an independent server into multiple virtual exclusive VPS services, while cloud servers use virtualization technology to schedule cluster server hardware devices on a large scale and treat them as virtualization products of "one" server.

two。 Different allocation of resources

VPS is a machine divided into multiple virtual spaces, in which some resources are shared, and sometimes there may be dozens or hundreds of VPS on a machine. However, on the CVM, the memory is exclusive, and there will be no situation in which everyone grabs the memory and no one can run.

3. Scalability is different.

VPS can choose different configurations such as bandwidth, CPU, memory and hard disk according to the needs of individual station construction, but once selected, it is not possible to change it later, that is to say, the resource configuration of VPS is fixed.

The most important feature of CVM is flexible expansion and dynamic load balancing. When bandwidth, memory and hard disk are insufficient, you can increase the corresponding resource allocation at any time and make use of elastic adjustment to meet various changing needs. At the same time, you can choose to pay on a monthly or annual basis, or you can pay according to the utilization rate, so that you can control the cost.

After reading the above, do you have any further understanding of the difference between a CVM and a vps? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
