In my experience there's much more transferability of skills laterally between cloud platforms than there is within the platform itself, ie. knowing how to design a high-volume transaction platform on Azure or AWS is going to be leveraging the same kind of technologies with the same kind of behaviors and features, the real change is going to be in details that in my opinion are quick to figure out. But arguably if you are specialized in building internal tooling in AWS, the gap to design an effective HVT platform in AWS will be much harder to fill. Same thing goes if your specialization is more on the infra side of AWS or on the application development using paas.
