Compared with other CDN service providers, the main advantages of CDN include stable and fast, cost-effective, easy to use, efficient and intelligent. More users will ask about the advantage of stability and speed. Generally speaking, CDN is characterized by sharing the pressure on the origin server, avoiding network congestion, accelerating the distribution of website content in different regions and different scenarios, and improving the speed of resource access. Here is an introduction to the principle of CDN acceleration service:

Can cdn speed up? Yes, the cdn system itself is a new way of network construction, through the distributed cache architecture for frequently accessed files to reduce network access latency, the goal is to speed up the delivery of application content to users.

Accelerated implementation method

Copies of the application files are saved in many places. When users visit, they will choose nodes close to these places, and the content does not need to be delivered over a long network, so it arrives faster to improve the user experience.

CDN nodes are located around the world and want to be as close to users as possible. It has its own URL load balancing parser that directs users to the nearest node no matter where they are, depending on their geographic location.

Cdn acceleration principle

CDN is a content distribution network built on the network, relying on the edge servers deployed everywhere, through the load balancing, content distribution, scheduling and other functional modules of the central platform, so that users can get the content they need nearby, reduce network congestion, and improve user access response speed and hit rate. The key technologies of CDN are content storage and distribution technology.

A variety of cache servers are widely used, and these cache servers are distributed to areas or networks where users are relatively concentrated. When users visit the website, they use the global load technology to access the users. Point to the nearest working cache server, and the cache server directly responds to the user's request.

The above is an introduction to cdn acceleration.
