IaC is awesome ๐ lemm.ee is deployed using Terraform.
My
lemmy_serverredundancy is mostly just so I can do infra changes without downtime (just take one node out of the load balancer, redeploy it and put the new one in), but it does also help a bit with general performance. I agree it's not strictly necessary, the vast majority of other instances are just running on a single server, but I do think it's very nice to have.For back-ups, I have point-in-time recovery, so I can restore the database to any random timestamp - and it has actually come in useful once already when two weeks ago I was able to restore to a good state about a few minutes after a problem - I think nobody even noticed that anything happened in that case ๐
Problem with Terraform is it assumes cloud providers, which tend to be expensive (or at least, I don't know a way to do terraform on hetzner dedis :D )
My solution is to get cheapskate VPS and dedis and loadbalance them as frontends. The VM request is manual, but I only have to do this once anyway. It's what I'm currently doing with the AI Horde. Of course, that doesn't help when there's DB changes but still.
What object storage are you using btw? I'm thinking to move to R2 or smt since I've had good experience with them until now. Contabo's is way cheaper but when I tried to use it for high-demand stuff it dropped dead on the spot. But it might be ok for Lemmy.
I can't thank you enough for sharing your knowledge, I am very interested in learning about server management and being able to read your thoughts is something I find extremely invaluable, please keep up with the great work! ๐
