TL;DR 5 but I could be using 1 I have 5 machine in a cluster right now running various services, it is definitely over provisioned, I'm barely using the machine's resources. I could technically host the whole thing on one server, but given what I'm building, I wanted to test out how my solution scales in a clustered setup. It's got an elixir backend, so the elixir apps are also clustered sharing data using LXDs fan networking. All the services get deployed / updated into the cluster via an automated CI / CD
