Why would you run only 1 VM in a situation where you would be running
100 containers?  You would run one container per application instance,
and you would run one VM in the same situation.

Sure, if you compare dumping all your services onto one VM to
isolating them the complexity sort-of goes down, but then I'm not sure
why you're even bothering to virtualize.

I will agree that if you already have 100 physical hosts it is going
to be easier to just migrate them 1:1 to 100 VMs.  However, putting an
application in a container isn't really any more complex than putting
them in a VM otherwise.
