Grokking is very superficial.

Do the work yourself, lazy ass

I actually saw this. Though this has good concepts, does not articulate things like number of connections per server, issues with scaling to millions of people. It’s a shame WhatsApp architecture is never discussed !
I initially thought you were asking for interviewing purposes not to actually build one yourself. That youtuber intentionally tries not to get that deep into the specifics like how many servers or how much traffic will be delivered because he’s focusing them on interviews. Having said that I don’t believe we’ll find answers as concrete as those you need so I’d encourage you to share anything you find along the way. Good luck!!
Is slack based on webrtc?
Have you tried their engineering blogs? https://developers.facebook.com/videos/f8-2016/a-look-at-whatsapp-engineering-for-success-at-scale/ http://highscalability.com/blog/2014/2/26/the-whatsapp-architecture-facebook-bought-for-19-billion.html
Yup but not very helpful
Actually it is. Don’t expect self contained solutions in those links, expect to learn design principles used in real life. Each principle can be further explored. Solutions for design problems are heavily dependent on constraints and use cases, but principles to use remain the same.
