Fastly offers an "on-the-fly," dynamic, video-on-demand content packaging service.

That video content then becomes immediately available to viewers.

Fastly's Streaming Delivery allows you to scale the delivery of your streaming content independently of any other HTTP content delivery supported by Fastly’s Full Site Delivery. You can also configure and control live and video on demand (VOD) caching using full site delivery, but there are advantages to using streaming delivery, such as more favorable streaming-specific pricing and a lower traffic load on your full site delivery service.
