What is the implementation principle of the CVM? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

CVM is that cloud service providers use server clusters to virtualize multiple performance-configurable virtual machines (VM) to monitor and manage all VM in the entire cluster system, and flexibly allocate and schedule resource pools according to actual resource usage.

If users want to use a CVM, they usually rent it through a cloud service provider. A good CVM is the basic facility for the development of an enterprise. You can evaluate whether the performance of the CVM is good or not from the following aspects.

Stability.

Does the server restart frequently? Does the website often fail to log in? Whether it is a server or a website, if problems often occur, it can be seen that it is unstable. The CVMs of most enterprises need to operate continuously 24 hours a day. Under such conditions, there will be great requirements for server performance, so we need to choose more mature servers to lease to maintain a stable state without downtime.

Manageability

A good CVM usually provides professional system monitoring and management functions, connecting websites and users at all times, even if there are vulnerabilities, they can be repaired as quickly as possible. When the computing node is physically damaged, the CVM can also migrate its business to other nodes to run in about 3 minutes, which greatly improves the reliability of the system.

Feasibility.

Judge whether the server lease can ensure the normal operation of the website, especially when the website occupies a large amount of memory, whether the running speed is still fast. CPU, memory, hard disk and other factors are the criteria for server feasibility evaluation. Only when the scale of the website becomes larger and larger, and the traffic, data and information processing capacity increase, the CVM can still operate normally, then it can be called feasible.

Expansibility

The purpose of the enterprise is always developing, and the traffic data and request information of the website will increase accordingly, so it is necessary to expand the server. A good CVM lease can install more internal and external hardware and operating system, while these application capabilities are expanded, it can also ensure that the network, bandwidth and other subsystems can bear enough load.
