Infosec is embracing the cloud since most of the stuff are in the cloud now. We are talking about Office365, Azure, Intune, etc.
Saying cloud is not the safe place to be is thinking backwards. Companies should adapt and assess the vendors hosting the cloud instance. The vendor in this case will be VMWare Dell.
Job Security is another topic. I believe if you constantly evolve your knowledge not just on VMs, on-prem stuff you should be okay. Besides, once you move to the cloud, the bulk work of stuff is still on the administration piece of AirWatch. Expand your knowledge on the latest stuff like Intune MAM and any mobility space like Android Enterprise etc.
