When organizing video distribution via a CDN (Content Delivery Network), a server is needed to host the original copies of the clips. This is known as the origin, which is used by the CDN to deliver the videos to the final users.
The CDN refers to the network of servers where the local copies of the files are located. Its main function is to increase the speed of delivery of these files, as it only caches one of them for a limited time.
This can cause slowness when requesting a file for the first time, or some time after the last request. The main benefit of this network is to help optimize the file path from the origin to the server that is closer to the user (edge).
