Varnish Cache as a robust distribution mechanism for HLS and HDS video

We recently came across an article on the Adobe blog that covers Adobe Media Server 5 (AMS5). AMS is an Adobe software product to help content publishers deliver video across platforms to various platforms.The article goes into details on setting up Varnish in front of AMS in order to increase performance and facilitate distribution of the content in order to build a robust video streaming solution.

HTTP video streaming, usually done through HLS or HDS is very well suited for distribution through Varnish Cache. The article basically explains how Varnish helps solve a challenge in the AMS5’s current architecture and how to configure Varnish for doing that.

When performance testing Varnish Cache with HLS video we’ve seen Varnish Cache push as much as 76 Gbit/s of content. Since each HTTP object is rather big the limiting factor is usually the bandwidth available. It’s not everyday we come across blog posts that so thoroughly go through Varnish Cache. Hats off to Karishma and Andrew for their write-up.
