This article is about how to choose the core number and bandwidth of CPU on CVM. The editor thinks it is very practical, so I hope you can learn something after reading this article. Let's take a look at it with the editor.

When purchasing a CVM, you need to choose the configuration according to your actual needs, such as CPU size, bandwidth size, etc. You cannot choose a CVM that is too small in order to save costs, nor can you easily choose a CVM with too high configuration, which will lead to a waste of cost. How many cores and how much bandwidth is appropriate for a CVM needs to be considered from different angles.

CPU Siz

CPU represents the computing power of a CVM. The higher the CPU, the better the performance of the CVM. If the website flow is small and a small number of pictures are displayed on the corporate website, it is recommended to choose 2 core or above CPU;. If the website traffic is large, there are more dynamic pages, and there are videos, it is recommended to choose 4 core or above CPU.

Bandwidth size

According to the nature of the site to choose the appropriate bandwidth, look at your site type, structure and visits and other indicators or estimate, the general new site, not many pictures, but also done to deal with, there are 2m enough. As long as the bandwidth is enough, it's not enough to add.

Reference formula for bandwidth calculation: support to connect individuals = server bandwidth / page size

Calculated according to the page size 60KB, the number of bandwidth links of 1Mbps = 1M/60KB=1024KB/60KB=17

Therefore, the 1m bandwidth can support 17 people online at the same time, and can support less than 3000 IP per day. If the pages of the website are relatively large, the number of users can be reduced.

For general corporate websites or blogs with less traffic, you can choose 1-5m bandwidth; for CDN, acceleration, video, games, software downloads, music online audio-visual, flash, online movies and other types, it is recommended to choose more than 50m bandwidth.

The above is how to choose the number of cores and bandwidth of CPU. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
