What is CDN?

CDN The full English name of Content Delivery Network is collectively referred to as the content distribution network. In layman's terms, it is to deploy edge nodes around the world to cache distributed content, allowing users to obtain resources nearby, reduce latency, speed up network transmission, and at the same time reduce the burden on the original server. More content visit: What is CDN? Understand the working principle of CDN in 5 minutes!

How does CDN work?

Simplely put, if your server is in the United States and your user is in Thailand, if you do not use a CDN, then your user will directly request the US server from Thailand. The restricted distance factor will make the network transmission slow. If you use a CDN, then the CDN will distribute your content to nodes around Thailand or Thailand. When a Thai user accesses, it will directly return information from the node, and the loading time and user experience will be greatly improved.

What are the advantages of using CDN?

1. Accelerate access and reduce latency: As the working principle of the above CDN, the use of CDN can cache static content and dynamic content is at the edge nodes near the user. By accelerating content loading, the user experience is better improved.
2. Reduce the pressure on the source station, because the user accesses the CDN node content, and the request to the source station is reduced, which greatly reduces the pressure on the source server. If you directly request it from the source server, the server's memory, bandwidth, and CPU consumption will be huge, and in some cases it will directly cause the server to go down.
3. Improve security, because CDNs are distributed in different nodes around the world, some rely on the number of nodes, and some are high-defense nodes. Regardless of that, these nodes integrate the waf function and can effectively resist DDOS and CC attacks. When some nodes are abnormal, the CDN will intelligently switch to normal nodes to ensure normal access by users.

What is a registration-free CDN?

As the name suggests, No registration is not required, because the Chinese mainland policy requires that all Internet projects operated in the mainland need to be registered through ICP before they can provide services. The exemption is through data centers such as Hong Kong and Japan that are not subject to policy restrictions and are relatively close to each other. The advantage of using a registration-free CDN is that it reduces the filing process and saves time, while avoiding mainland policy regulatory reviews, and reducing potential risks caused by filing failure to comply with legal requirements.
