PaaS

In traditional H.A. architectures, don't we already take care of the fact that in the worst case scenario, our entire region can go down? With services like Aurora or S3, the underlying storage layers automatically can replicate your data under the hood across not just the three availability zones but if you create them as regional data stores. Same with DynamoDB and a bunch of other services. When do you see customers wanting that sense of control and wanting to do this all by themselves? Given that searching over to PaaS services seems like a no-brainer in these scenarios.
