This 1000%. And this applies to a huge percentage of very large orgs/ISPs/telecoms/fortune 500s, etc. VMware for the most part “just works” and is entrenched in these companies, much like AD.
If you are rolling your own replacement of VMware, what happens if a couple (or even say 20 out of your 5000) of your “parent” hosts go down. Will all of your guests auto-migrate to healthy hosts?
And we are not talking about Kubernetes or similar here. That is very different. You don’t roll your own VMware alternative. You just use VMware.
