This article introduces the knowledge of "what is the difference between a CVM and a VPS host". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. CVM

Cloud host is an important part of cloud computing in infrastructure applications, which is located at the bottom of the pyramid of cloud computing industry chain. The products come from CloudEx elastic computing platform. The platform integrates the three core elements of Internet application: computing, storage and network, and provides public Internet infrastructure services for users. A CVM is a huge group of servers made up of one or more machines, and then the CVM is virtually divided from this large "independent server". The CVM can be hardware independent in the real sense, and the operation of your host will not be affected when a single server DOWN down due to hardware or other reasons, and because it is a "cloud" composed of multiple servers and multiple nodes. Therefore, it can prevent all kinds of attacks and instant seamless migration, so as to ensure the stability and security of the server.

2. VPS host

VPS host English: Virtual Private Server professional name: virtual dedicated server uses virtual server software to create multiple small servers isolated from each other on a physical server. These small servers (VPS) have their own operating system, which runs and manages exactly the same as stand-alone servers. The VPS host is a scaled-down version of the independent server, which can do exactly the same function as the independent server. The difference is that VPS is a number of independent and independent small hosts on the independent server. It integrates high-performance servers and high-quality network bandwidth, effectively solves the shortcomings of traditional host rental prices and uneven services, and can fully meet the needs of small and medium-sized enterprises and individual webmaster users for host rental services with low cost, high reliability and easy management.

3. The difference between CVM and VPS

VPS is a host that runs multiple virtual servers that are independent of each other. The VPS host uses a RAID5 hard disk array, so the data is very secure. The disadvantage is that if there is a problem with the host hardware, the website can not operate normally until it is well maintained and used. On the contrary, the CVM has done a very good job in this respect. A cloud host is a large group of servers made up of one or more machines, and then the cloud host is virtually divided from this large "independent server". When a single server DOWN down due to hardware or other reasons, it will not affect the operation of your host, and because it is a "cloud" composed of multiple servers and nodes, it can prevent all kinds of attacks and migrate seamlessly in real time, so as to ensure the stability and security of the server. In addition, the scalability of the CVM can be expanded at any time, and the computing power can exceed that of a single physical machine.
