Trying to utilize all three major US cloud providers with their cloud native tools simultaneously, learning those tools and cutting IT, dev and security from on prem to those, takes a massive staff in a regulated industry. Doing it "right the first time" in one of the big three, then building a skunk works to replicate efforts as a blackout scenario, seems much more cost effective. The key term is Total Cost of Ownership. Lockin is a cost. Legacy stacks are a cost. Learning three times the tools are a cost.
