What is the use of CDN acceleration?

——Benefits for guest users
For users, if a website has CDN turned on, the user access speed or download speed will be faster than when it is not turned on. Generally, as long as some better websites, the CDN function will be enabled, mainly to improve the user experience. For example, using Xunlei to speed up downloading things, the acceleration here is also based on CDN technology.
——Benefits to the website
For websites or webmasters, turning on CDN can not only improve the website opening speed, but also improve the user experience. More importantly, opening a CDN can reduce the pressure on hacking tools and server bandwidth.
After opening the CDN website, users in different regions will access different servers, and the real server (source server) of the website is generally only accessed by the CDN node. The CDN node server accessed by users across the country does not directly access the source server. In this way, the broadband resources of the website server can be introduced and the pressure on the server can be reduced.
In addition, due to the middle blocking protection of CDN nodes, the security of the original server can be better protected. That is to say, CDN provides a surrogate for the user's origin server in the secure cloud. Whether it is infiltration or DDOS attack, the target of the attack will be the surrogate of the CDN node, thereby protecting the origin of the website.
