About Fastly's Video Caching service
For customers with their own video packaging infrastructure, Fastly can act as a globally distributed HTTP cache to improve quality of service and increase viewer capacity. When a manifest or video segment is requested by a customer's player, a Fastly edge or shield POP will pull the requested content from the customer's origin media server. Subsequent requests for that content will be served from Fastly's cache servers instead of the customer's origin (read How Fastly's CDN Services Work for more information).
Fastly can cache and deliver any HTTP based media streaming protocol including:
- HTTP Live Streaming (HLS),
- HTTP Dynamic Streaming (HDS),
- HTTP Smooth Streaming (HSS), and
- Dynamic Adaptive Streaming over HTTP (MPEG-DASH).
In addition, both live and on-demand streams are supported.
