Phil,
As per my experience for teaching both the courses Openstack & Openshift to a wide variety of customers across the globe i have come to an undrestanding that currently companies are deploying openshift on either their bare metal or are in POC stage in a virtual environment.
Some of the companies have adopted openshift however they do not use openstack i feel the benefit lies in using openstack to scale the nodes using HEAT template triggered by either a CPU spkie which attached automatically into the openshift cluster.
One of our customers in EU (telco) have deployed openstack and are deploying openshift, i believe if we focus on openshift for a faster delivery and CI/CD integration and build openstack specifically for scaling out nodes then it could be a great choice for the customers.
More ever not just openshift, Openstack can be used to add additional projects in future so in case companies want to add virtual machines openstack provides the ability.
Hope this helps !
