There are a TON of different tutorials and videos.
If you’re looking for a beginner friendly interface for your servers; I recommend “Cockpit” you just “sudo apt-get install cockpit” and it gives you a nice to use web interface to manage most of your servers, you can then install plugins as needed, for example you can install net bird or Pangolin to make it accessible from the internet.
If you want something more like what I’m doing here (Virtualization) you can try Canonical’s version of this which runs on ubuntu, They’re called LXD https://canonical.com/lxd/manage
Basically they’re tiny ritualized linux instances inside of your main ubuntu server (Containers) with their own kernel so that changes on the base server don’t bother your other apps.
