What is the difference between a CVM and a virtual host? many beginners are not very clear about it. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The development of cloud computing has led to a comprehensive burst of virtualization applications. In the domestic IDC industry, cloud servers and virtual hosts are two very common products.

CVM

It is a virtual independent server based on cloud computing platform, which has higher intelligence, allows users to define server configuration independently, makes full use of resources, and integrates the three core elements of Internet application: computing, storage and network. provide public Internet infrastructure services for users.

A CVM is a cluster of several servers that provide services at the same time. Assuming that one or two servers in the cluster are down, it will not affect the normal use of the CVM. The disk IO performance, bandwidth and memory of the CVM are not limited by a single server, and can be expanded flexibly and conveniently. As the name implies, the CVM is virtualized on the basis of the server cluster.

In the era of cloud computing, cloud servers are welcomed by the majority of enterprise users because of their scalability, security, reliability and flexibility.

Virtual host

That is, the shared host, from the birth of the Internet to now, the vast majority of webmasters are from the "shared host" to start the process of building the station. The so-called "shared host" means that there are many websites on a server, and everyone shares the hardware and bandwidth of the server.

Virtual host is the use of virtual technology to divide a complete server host into several hosts, and a certain disk space is divided on the network server for users to place sites, application components and so on. Each virtual host has a complete Internet server function.

On the same hardware and the same operating system, different server programs that are opened for multiple users do not interfere with each other, and each user has its own part of the system resources. Virtual space technology enables multiple users to share resources and share operating costs, which greatly reduces the cost of building a station for each user and provides great convenience for the popularization of small and medium-sized websites.
