as an answer: tare actually two ways to run it. As a standalone binary, it's one process you run(you can easily run it via docker too) on its own(which speaks on Redis protocol over TCP) - and any language connects to it like a Redis server.

Or, if you're on Elixir, you can skip the separate process entirely and add it directly to your app's supervision tree - it runs inside your own app's process, no network hop, just function calls.
