CNAME domain name

After the acceleration domain name is created on the developer platform, a "CNAME domain name" will be assigned to the domain name (example. qiniudns. com). The user needs to configure a CNAME record at the domain name service provider, point the domain name to be accelerated to the example.qiniudns.com domain name record, and after it takes effect, the domain name will officially point to the CDN, and all requests for the domain name will begin to enjoy the CDN acceleration effect.

DNS

Namely Domain Name System, the domain name resolution service. Converting domain names into IP addresses that can be recognized by the network (people are used to memorizing domain names, but machines only recognize each other's IP addresses) can make it easier for people to access the Internet. The conversion between them is called domain name resolution.

Edge node

The CDN node closest to the end user can improve the response speed and connection speed, and improve the user's experience of browsing web videos. The main task of the edge node is to save the web content, audio and video files with a large number of visits on the dedicated cache device at the front end of the server.

Origin

That is, the customer's business server.
