From the top of my head: Proxmox and Kubernetes, Rook on top of that for storage. GitLab for manifest storage, ArgoCD for deployment, terraform for node management in proxmox. It's not fully redundant (two separate nodes) but storage is replicated (ZFS send/receive on proxmox, Ceph replication for Rook). Primary stuff are things like AP management, file shares, prometheus, grafana, various interfaces with 'dumb' devices, just to collect data from them without having them connected to the internet, VPN for remote access, separate VPN for internet tunnelling when on foreign networks, media service for movies and series, downloaders, Cloudflare tunnels to expose services to the big bad internet without opening ports, TFTP services for network booting, pull through caches for OCI resources and some other package indices. Also an OpenFlow controller but that was more for fun than because I needed it, no longer used for actual switches. Main benefit from all the IaC is easy creation/destruction of entire environments when testing out things without having to pay money to a public cloud. Also have BSD based firewall(s) to do NAT, DNS, DHCP etc. but those aren't on a shared home server but rather on separate hardware. Similar setup in leased hardware in a DC just to keep the knowledge for legacy setups in on-prem style cases fresh, and public cloud version as well (but that costs money so it's scaled down significantly)/
