Those aren&#x27;t private datacenters.  Amazon&#x2F;Azure&#x2F;Rackspace&#x2F;Google Cloud are public datacenters providing services for customers, so they will obviously be using virtualization.  Personally I think public cloud is going to kill private cloud altogether, but that&#x27;s an entirely different discussion.
But in the specific case of private datacenters, I believe, virtualization is dead, and many of my colleagues share the same opinion.  Just because it&#x27;s not common around the world doesn&#x27;t mean that the change in trend and thoughts hasn&#x27;t hit an inflection point.  Virtualization has done an amazing job, and there&#x27;s a reason why it has become so popular.  But just like all other technologies, I think its going to be passed for something simpler that scales better.
