@statsguy I refuse to say "running Linux" as that unfairly reduces what Proxmox does.
Also - "a" server ?!
Across my Proxmox cluster I have 70 cores and 190 GiB of memory. But in addition to that I have 4 NAS (arranged as 3 virtual), and insane amounts of networking hardware!
Supported by all that are several VMs (Home Assistant a big one), a few low level containers (Hashicorp Vault cluster for example), and several Kubernetes clusters. One of those contains and runs all my home automation that exists outside of Home Assistant (which is a lot), another one manages the first with the Argo suite so everything can be deployed with GitOps and is easy to repair/replace if needed. Another is a static cluster for playing _within_, but then I also have several clusters I can tear down and recreate at any time for playing with the actual clusters. And the last one I have isolated with VLANs and then exposed with a special VPN for a former co-worker to use as a lab π
