At a former company our development teams addressed this by making their own API gateways to talk to API's in AWS and Azure so that the same primary codebase could run in multiple clouds. I do not have specific details but this is absolutely a concern. I am not aware of a turn-key solution to address this. OpenShift would still need code to talk to all the API interfaces of each cloud vendor I have no idea if this is already baked in at this point. It is a bit of work up front but worth while in my opinion.
