Right, I get containers. I use LXC containers in Proxmox. I have only a couple
uses of Docker and no Kubernetes.
Using Docker or Kubernetes would mean an additional pane of glass that I don't
have time for.

Containers like Docker (or Kubernetes) are a much more efficient use of
resources. Many of the resources consumed by VMs get replicated when you are
running many of them. With containers, the OS part of the VMs gets shared. If
you need to run different kinds of VMs (like Windows), then VMs might be
better. Actually, you could run two VMs (one for Windows, and one for Linux)
and then just run containers for the various jobs.

I've never bought into Docker at all. It just seemed like an extra layer of
crap compared to manually setting up LXC containers in Proxmox.
I also fully admit that I may not know what I'm talking about.
Some are Windows, some are Linux, some have to be VMs to get software support,
etc.

Huh, then you might want to consider just using Docker…

Three or four? I run... 20 - 30 VMs per host.

VMs are a great way to go depending on the job(s) you need to do. As it happens
a lot of jobs (e.g. DNS) are not particularly compute intensive, so it's a
great way to stretch resources. We find we can run 3 or 4 virtual machines on
each physical machine.
We used VMware from the get-go, but did not get many of the paid-for bells and
whistles. VMware can become pretty expensive, where other solutions (e.g.
Proxmox) has an advantage because of open source.
The other consideration is containers, which can be thought of as VM-lite.
Containers provide almost all of the advantages of VMs with a significantly
lighter load on the hardware. As a result, you can load up more applications on
less hardware. The leading contender in the container space is Kubernetes and
it's also open source.
Pick your poison with someone you know who can go over your requirements.

I want something that will at least do some monitoring of VM's, backups,
snapshots, etc. Managed upgrading would be great but not as big a priority for
me (at least I don't think so).
Since I don't know what I don't know, I am asking the experienced crowd.
It seems the two real choices are VMWare and Zen. Are there others? Commercial
support seems nice, is it worth paying for? What I will run is important for
sure.
I spent a few hours last night and I more confused now than when I started.
