The difference is it's likely possible to have 7 physical servers replace those 700VMs when you have your own hardware without all the overhead.

It is much easier to maintain when you look at those numbers.

Not in my case.

Every VM had 4 cores and 20gig me.

Run on quite big blades

Your case is fine. AMD's 4th-Gen EPYC Genoa processors can do up to 192 cores and 384 threads in a single machine (2 socket) with TBs of RAM.

In most cloud environments a "core" can be just a thread.

Older machines have had 4-CPU socket based chassis with many cores as well. Definitely doable.
