For those self-hosting a lemmy instance, what hardware are you using? I am currently using a small Hetzner VPS. It has 2 vCPU, 2GB RAM and 40GB SSD storage. My instance is currently just in testing with me as the only user, but I plan to use it for close friends or family that may want to try this out, but might not want to sign up for a different instance. My CPU and RAM usage is great so far. My only concern is how large the storage will balloon to over time. I’ve been up for ~20 hours and it’s grown to 1.5G total volume since.
It’s definitely overkill, but right now I’m hosting it on my nomad cluster. It only has 4cpu/8gb allocated at the moment but will autoscale (vertically) if needed. I already have a separate postgres cluster used for other things so I’m just borrowing that for now too. I haven’t tried running multiple instances yet but I’ll probably test that out this week to see how/if it works.
