Today, I'm going to talk to you about how to choose the bandwidth of a CVM. Many people may not know much about it. In order to make you understand better, the editor summarized the following. I hope you can get something from this article.

We often compare which CVM is better from different angles, such as price, configuration, performance, speed, etc., and bandwidth is also one of the important aspects. How to choose the bandwidth of a CVM is also a topic of great concern to many users, because as we all know, in the process of purchasing a CVM, you have to pay to use or increase the bandwidth.

Different manufacturers have different billing standards for the bandwidth of CVM. To measure which CVM is good in this respect, it is no doubt that enterprises with low bandwidth costs are more popular. Among the well-known cloud service providers, the bandwidth fees of servers such as Aliyun and Tencent Cloud are very expensive. Webmasters or enterprises who have used them all know that increasing bandwidth requires a lot of extra fees. Relatively speaking, the bandwidth is much more cost-effective.

So how should we choose the bandwidth of the CVM to determine the most appropriate bandwidth megabytes for our website?

1. Pictures, text or static websites

If it is an ordinary small website, there are pictures, text, news and information types of websites, as long as not visited in the same second, and the picture is not large, 1m bandwidth is no problem. But the bandwidth of 1Mbps, the theoretical download speed is 128kb/s, if the image loaded on the page has 1MB, then the first person to load nearly 10 seconds. For those who visit later, the text of the web page may be normal, but the picture load is very slow. Therefore, the bandwidth occupied by normal SME stations is about between 2M-5M. If it is a video site or download site, it is far more than that.

If it is downloading, it depends on the number of concurrent connections. Finally, divide the number of concurrency by the bandwidth occupied by each person. For example: 2400 people are online at the same time, 2400 people operate at the same time, and each person's page 30KB, then the cost-effective bandwidth is: 2400 / (30KB*8) = 10Mb

two。 Forums or websites with interactive classes

For forums with a daily IP of 8000, it is best to refer to the original configuration and set aside some redundancy. If the average bandwidth on the original server is 5m and the peak is about 8m, it is recommended to purchase 8m of bandwidth. If you are using a virtual host and use a CVM for the first time, it is recommended to use the configuration of 4-core CPU/4G memory / 5m bandwidth. If it is not enough, you can add it later.

3. Video, audio or streaming station

For example, in the network environment, the number of concurrency is 1000, the bitrate of HD video is 2Mbps, and the bitrate of standard definition is 1Mbps. If: at 1:2, a single node is calculated concurrently by 600, then its total output bandwidth is 2002+4001=800Mbps

Online shopping malls or download type websites, such as video sites, need hundreds of megabytes of bandwidth, depending on the situation of the site. Otherwise, the bandwidth is too small to ensure the normal access speed of the website, affecting the user experience.

In addition, for some service providers with different CVM payment models, it is more appropriate to use bandwidth billing if the user is a website with a fixed number of visits and a fixed peak traffic.

After reading the above, do you have any further understanding of how to choose the bandwidth of the CVM? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
