well I grew up provisioning and using dedicated servers and nowadays you get much tighter security from the container ecosystem that I would on a dedicated server.
I have just provisioned another bare metal k8s cluster, taking software of dedicated servers and.... well if I dont have to, im not running bare metal anymore in 2022.
If you want to just "get a computer in there" have a look at harvester, its the best of the two worlds
You seem to have missed the alternative "get a computer" in between there.
