proxmox and then you can run either LXC containers directly on it or VMs when necessary. Almost anything linux-based can be in a container on proxmox and has no need for an actual VM. I have a mini cluster of 3 proxmox servers running jellyfin, all and the -arrs, nzbget, nginx, searxng, pihole, ombi, seaweedfs, streammaster, dizquetv, syncthing, nitter, teddit, piped, vaultwarden, changedetector, freshrss, headscale, rimgo, nextcloud, ntfy, quetre, uptime kuma, homeassistant, kavita, scribe, nzbget and a Windows Server VM. The stuff could all run on one of them, but I like to be able to move stuff around since the 3 instances are not all the same. One is an older server that I’ve had forever. One is about 5 years old, but has 32GB of RAM and 60+TB of disk. The new one has 64GB and an SSD that will do about 7GB/s.
