Remember Disney+ isn't completely new software, Disney acquired MLBtv aka BAMtech to run the site. And their business is live streaming, not "merely" VoD.
BAMtech was spun out of MLB Advanced Media, has been doing streaming since 2002. If you could choose anybody to rely on to launch D+ they’re at the top of the list.
Ya, I don't have too much in terms of insidery baseball. But I did have some colleagues at MLB in nyc. I recall it was pretty much a Java shop. With Akami providing extensive CDN support.
If one is interested in rolling one's own clone of Netflix. there isn't really a tutorial or course to watch to learn how its done. And there very much should be.
The closest you can get is probably Dave Hahn's Day in the Life of a Netflix Engineer series from AWS re:Invent
BAMTech has had high volume days, obviously, but on reflection I couldn't think of any service launch they powered that'd be bigger than this. WWE, HBO relaunch, NHL, MLB -- none seem likely to generate as much demand as this.
