From what I know there is a secret sauce beyond a mere AMI and a control plane, based on some EBS volumes magic. I may be mixing things up with Aurora though.

this is very, very safe to assume. There is probably a hundred engineer's worth of "secret sauce" for an entire managed DB product line.

There were some comments in the early days that the Multi-AZ magic for classic RDS was just drbd on top of EBS.

Aurora is a completely different approach where the RDBMS code is modified to directly interface with EBS instead of going through a traditional OS filesystem layer.
