What should I pay attention to when purchasing a 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.

Nowadays, the development of cloud computing is accelerating. Because of its high security and good stability, cloud servers are more popular in the market than traditional servers. Both enterprises and individual webmasters will choose cloud servers. Here are some points for attention when purchasing CVM:

Pay attention to memory

I believe everyone is familiar with memory, and the memory size of CVM will also affect the running speed. If the website does not have enough memory, it will affect the normal operation, and the capacity will be expanded in the later stage. Therefore, in the early stage of purchase, you should estimate the website situation to select the memory of the CVM. In addition, the server hard disk is a data warehouse, where all software and user data are stored, so there must be sufficient reserved space.

CPU kernel number

It refers to the number of cores such as 1 core and 2 cores of a CPU. The processing speed of a CVM varies with the number of cores in CVM. The higher the number of cores, the stronger the running capacity of the server, and the more expensive it is. General individual users and sites with a small order of magnitude, 1 core and 2 cores are recommended.

Pay attention to bandwidth

In addition to the server hardware configuration, the bandwidth of the CVM is one of the most important factors. The size of the bandwidth will directly affect the user's access. If the peak of access greatly exceeds the amount that the bandwidth can hold, access will be slow or even inaccessible. DD attacks officially attack websites in this way.

Operating system

At present, Linux and windows are the two main operating systems for CVM rental on the market. If you use a server to build a website, it is recommended to use Linux. If it is rented to use or access public network and other operations, it is recommended to use windows.

It is very important to purchase appropriate cloud servers, which can help enterprises build more stable and secure application systems, thus further improve the efficiency of operation and maintenance, greatly reduce IT costs, and enable enterprises to focus on core business innovation.

Users can freely choose CPU, memory, data disk, bandwidth and other configurations of CVM according to their needs. They can also upgrade bandwidth without downtime at any time, and upgrade CPU and memory within 1 minute to support the continuous development of the business.
