What are the advantages of cdn?

After purchasing the CDN service, users will be more concerned about the actual effect in the process of using it. First of all, you need to make sure that it has been activated successfully, and then follow the basic steps to add accelerated domain names and configure CNAME. After all these have been successfully completed, CDN can be used normally. Many users have a question, which is often asked, that is, what are the advantages of CDN?

What are the advantages of cdn? Now more and more websites will choose to use cdn acceleration service if conditions permit. The advantages of cdn are mainly reflected in the following aspects.

Conducive to website ranking

For example, Baidu regards the opening speed of the website as a more important indicator, so the speed of opening the website will affect Baidu's ranking. After using CDN, the website opens faster, which can reduce the bounce rate and increase the user-friendly experience of the site.

Acceleration across regions and operators

It avoids the embarrassing problem of access reduction caused by different operator lines. If the enterprise's website cloud server is in Beijing and the operator is Telecom, when Unicom users in Guangdong visit the enterprise website, because of cross-regional and cross-operator reasons, the opening speed of the website will be much slower than that of local telecom customers in Beijing, which can easily lead to the loss of customers in this enterprise.

Optimize server performance

If the performance of the cloud server of a website is relatively poor, the carrying capacity is limited, and sometimes it is faced with sudden traffic, it is easy to directly cause the server to crash and the website cannot be opened, especially when the visit volume of the e-commerce website is concentrated during the festival. in this case, the website cannot be opened, and sales are bound to be greatly lost.

Reduce resource requests

Whether it is a static website or a dynamic website, such as pictures, icons, css files, js files, etc., as long as the cache exists in the CDN node, it will be opened smoothly.

Improve the security and stability of the website

Because CDN nodes are dispersed, it is difficult for network attackers to attack, and attacking one node only affects the cache access of one node, and CDN will automatically enable another node. If there are enough CDN service nodes, the traffic packet cost required by the attacker will increase step by step, so the attack cost will increase accordingly.

This is an introduction to the advantages of cdn.
