Sidekicks (..or what else do you have up and running besides HA?)

I’ve recently redone my environment. And reviewing what else I have around and what to move where…

What common sidekicks do you have installed besides HA?

I’m running a Proxmox server with a NAS for pure backup purpose.

HA went into a VM
deconz went into the VM also. (Scrapped a Tradfri and Hue)
Thinking of moving MariaDB into the HA VM

Perhaps running a media server and a file server virtualised also? Or create a generic one with them in dockers/portainer + watchtower?
