Right now I run them as two separate services. Phoenix does all the user signup and management, landing page, docs and vends API keys while I use Rust for the API product itself, which does some cpu bound work where Elixir would have been weaker. They both share a Postgres database where the Rust API is restricted to the api keys table.

There is also Rustler which helps facilitate calling Rust binaries from Elixir directly but I opted to deploy them separately.
