Either at work or for your own projects - what sort of things will you be making with Elixir?
Apps that revolve around realtime interactions. Since handling a bunch of processes is a strength of the framework I’ve been taking it heavily into account.
But I also wonder if I have a bunch of different processes spawning that if I were to deploy it to Heroku it may use up a lot of bandwidth and I won’t be able to afford it.
I don’t think that would be the case as Elixir/Erlang would make the most efficient use of the available cpu power - so if anything you will use less resources, than say the same app built in most other tech
It may depend on what you mean by realtime. Elixir is meant for soft-realtime, IIRC. Hard.realtime probably needs something more low level.
