All the things! I've got a hybrid VMware cluster (two nodes at home and one in a DC) with a bunch of VMs for stuff like Plex, Plesk, Gitlab, Lemmy, Stable Diffusion, etc. also running a 5-node Rancher k8s cluster.

Some of my public services do actually run from home but are routed through ZeroTier to my Nginx Proxy Manager appliance.

Pretty much everything is running RHEL8 or CoreOS after a recent migration. Veeam for backups (two community instances since I'm too cheap to pay for licensing for personal stuff).
