A CDN intermediate source, also known as an edge server or point of presence (PoP), is a server located at various strategic points around the world to ensure fast and efficient delivery of content to end-users. These servers cache content from the origin server and serve it directly to users from the closest PoP, reducing latency and improving load times.
For example, when a user in New York requests a video from a website hosted in Los Angeles, the request is first routed to the nearest CDN edge server, which might be in New York City. This edge server checks if it has a cached version of the video. If it does, the video is delivered directly to the user from the edge server, avoiding the longer distance to the origin server in Los Angeles.
In the context of cloud services, Tencent Cloud offers a Content Delivery Network (CDN) service that utilizes a global network of edge servers to accelerate content delivery. This service can be particularly useful for websites and applications requiring high-speed content delivery, such as video streaming, file downloads, and web applications.
