How to choose and purchase a CVM? Many novices are not very clear about this. 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.

When choosing a CVM, we can follow several principles and make a comprehensive consideration from different angles.

Expandability principle

CPU model upgrade, memory expansion, hard disk expansion, replacement of network cards, increase the number of terminals, attach disk arrays or form a cluster system with other servers for concurrent access to centralized data, etc. All this requires that the selected server has a good room for expansion as a whole.

The IO of the CVM should be high, otherwise a bottleneck will occur when both CPU and memory are of high performance. In addition, the scalability of the server is better, in order to meet the needs of the development of enterprises in the future.

Safety principle

The server deals with the core data of the relevant system, storing and running key transactions and important data. They are very sensitive to security. The security of the CVM is closely related to the overall security of the system. The server itself, including hardware and software, should be designed and considered from the perspective of security, with the help of external security facilities, but also to ensure its own high security.

First of all, in terms of the materials of the server, it is necessary to have conditions such as high hardness and high protection, and secondly, the cooling system of the server and the ability to adapt to the environment should be strong, so as to meet the security requirements of the server in hardware.

Manageability principle

The server is not only the core but also a node part of the whole system, just as the network system needs management and maintenance, it also needs to manage the server effectively. This requires the software and hardware of the server to support the standard management system, especially the operating system, including some important system components. Try to choose servers that support more systems, because the more systems that are compatible with cloud servers, the more options you have.
