Would you mind elaborating. I'm definitely looking for a PasS for Elixir/Phoenix + Postgres.
That said, our stack does make things Elixir folks need very easy. In particular:
* Private network and built in service discovery mean clustering just works
* You can connect to your private network with WireGuard and then use iex or similar to inspect running Elixir processes: https://fly.io/blog/observing-elixir-in-production/
* Postgres setup is pretty magical. "fly postgres attach" gets your app all connected and auth'ed to your Postgres cluster.
* And, most importantly, we actually are the best place to run an Elixir app if you're using Phoenix LiveView. You can push your app servers out close to people and make LiveView incredibly responsive: https://liveview-counter.fly.dev/
