Having done both Rails and Elixir, Elixir is vastly easier to scale. Not just because it can use up all the available cores, but also because a REPL in a production environment makes troubleshooting and identifying bottlenecks easier. When I scaled Rails, it was a struggle, and the epiphany I had when I had to modify how Sidekick worked was that Elixir and Erlang had built-in primitives to do what is major refactor of Sidekick to get Sidekick to do what I want. One of the things I had success with in a non-web applications is writing Kubernetes Operators in Elixir. Though I also want to experiment with the embedded Prolog-in-Elixir for those.
