Resources for small and large instances (lemmy.ml)

I'm wondering, what resources does Lemmy need? For a small instance (let's say, me and some friends) or a large instance (think Lemmy.ml or Lemmy.world or the like...).

Also, where do y'all host your instances?

I'm running this instance I'm posting this from (single user) on a Hetzner CX21 (2 core / 4 GB ram / 40 GB storage)

The current stats (according to podman) are as follows

NAME        CPU %       MEM USAGE / LIMIT  MEM %       NET IO             BLOCK IO           PIDS        CPU TIME       AVG CPU %

Net IO is inaccurate as that also includes networking between the individual containers (I'm definitely not exposing postgres to the wider world, at least not intentionally)

Oh, and images are using about 200MB disk space so far, although this server hasn't been up for more than 24 hours even, so we'll see how that goes.

Is it shitty setting an instance up or is it doable? Are u running on perm or via a provider?

Definitely needs some work. The instructions are all over the place, the Ansible roles expect to be the only thing in your system (unfortunately common), both the manual and Docker installation guides are meh and partially unsupported. Caddy is a config snippet and "good luck" (implied, they don't put it that bluntly). I'm sure there are a fair few people who are accidentally running a dev-focused setup on prod.

TLDR: It's definitely not for the newcomer. I may throw my own configs up somewhere for future reference.

Not sure what you mean by that.

Think they meant on-premise or hosted services. Is it your owned box or are you paying to rent one.
