I wonder what they switch to at WhatsApp when they become medium scale.
- busterarm 5y agoHey. I write Elixir & Erlang sometimes too. I'm an Erlang Ecosystem Foundation member. There are very real and well-known scalability limits of Erlang clusters and applications that run in them. This isn't someone talking shit, but instead just operating within the limitations imposed by reality. Message passing has overhead -- it's not free. WhatsApp probably doesn't need nearly as much hardware as you think.
