I'm interested more about how you are doing deployments of elixir/phoenix app, and your dev setup ... like do you use docker for developing and production and stuffs like that ...
I don't use docker - I have never really used it and wasn't going to start. It's using one DO server, a 4 vCPU, but could be using much much less. Before posting I upgraded it from a 5$ machine
The turnserver is a $5 DO server.
Feel free to email me - ben@readastorytome.com and I will gladly fill you in on all the nitty details around the deployment. It's embarrassingly simple :)
