I run a little kube cluster on it that serves as the brain for my home lab on it and it’s been cranking along just fine for the better part of half a year. It’s all IaC and ephemeral so if it died tomorrow I could just restart it. Quite generous for $0

Can you feasibly run a homelab C&C server on the free tier of any of the big 3?

It’s possible to run a single node cluster on GCP for almost free, especially if you’re creative with spot instance. But afaik, not really otherwise. OCI is far and away more generous, giving you 4 dedicated always on nodes, which is just enough to run a decent mini cluster

I know you're talking about the cloud offerings, but the idea of using just a little bit of crack as "not production" is hilarious to me.
