In some orgs the move to the cloud was driven by accountants. In my org it was driven by lawyers. With GDPR on the horizon and murmurs of other data privacy laws that might (but didn't) require data to be stored in that customer's jurisdiction, we needed to host in additional regions.
We had a couple rather large datacenters, but both were in the US. The only infrastructure we had in the EU was one small server closet. We had no hosting capacity in Brazil, China, etc. Multi-region availability drove us to the cloud - just not in the "high availability" sense of the term.
