Resource Origin
The Origin (or the Source Server) — Your physical or virtual HTTP(S)-accessible server hosting the source directory with files you intend to distribute via the CDN, primarily designed to handle incoming requests. For example, the origin may host your website’s source code or content folders. Anycast CDN uses the source server to cache the original files and proxy requests for non-cached files.
If you don’t have a strong reason to use third-party cloud storage, we strongly recommend using our native Cloud Storage as your cloud origin.
