They use more than just Java. The UI was originally C#... I'm still surprised the front-end was C# but they went with Java longer term for the backend.

When I worked at OpenConnect (Netflix's CDN) there was a lot of Python too, and I started porting a lot of the tooling to Go. By the time I left (2019), Go was really starting to take off outside of OpenConnect too -- but yes, there's historically a huge amount of Java there.

Likely because Netflix relied on Silverlight for video playback early on. I'd be surprised if they still had C# in their front-end stack (and I say that as a general C# fan, though I use it on the back-end).

		My favorite thing about it having Silverlight is Silverlight actually worked on Linux better than Flash did. I think I used the Mono version of it though, I don't remember?

Their UI originally was Silverlight which at that time had the best "adaptive streaming" story.
