While I agree that deployment can still improve, it is mostly because it doesn’t have the same polish as everything else Elixir ships with. In any case, it has already improved considerably over the last year.

My first application was deployed to Heroku and it just worked. For AWS, we had to do some research but once we got Distillery running, everything worked without major concerns. And Distillery uses Erlang releases which have been around for decades so we can rely on its stability.

Btw, runtime configuration works like a breeze in Distillery 2.0, which is the result of Paul’s amazing work at Dockyard (among other things).
