> Looking into Elixir, but from what i've heard, Elixir isn't very memory efficient when it comes to web servers.

It really depends on your reference point and what your web servers are doing. The Elixir website has a series of cases and perhaps you can find an example closer to what you are doing: https://elixir-lang.org/cases.html - there are also cases where companies reduced the number of nodes in production once they migrated to Elixir.

Regarding deployments, Heroku, Gigalixir, Fly.io, Droplets, K8s, etc are all viable options.
