I work at a company that recently tried to shift our (on prem, sharded, 2-metro, 6 replica) mysql deployment to AWS. Any way we sliced it, even after steep discounts, we were seeing massive TCO increases, often up to 10x - the math just doesn't work out for large deployments. It's really a shame that all these companies are forced to write their own (crappy) version of AWS - but price is a feature when it comes to this stuff.
