We started to use Elixir around mid 2016, we were mostly using rails/sidekiq stack at that point and started to face scaling issues with sidekiq. Moved small parts to Elixir first and then later started to use it for most of the new services. We had to create new libraries for some specific use cases. Apart from that, it was mostly smooth experience. We rarely had to tune or adjust the code for performance. Today we have a big monorepo with 20+ apps. My long term concerns are more about whether the tooling will work if we try to scale it to 100+ apps with a single monorepo. We majorly depend on Plug, hackney, Exq, brod and Ecto.
