Only if they evaluated RDS and found it wanting. They don't even mention testing it.

It's not in the post, but I answered this in a separate thread. RDS doesn't let us provision as many IOPS as we need.

Apparently Aurora behaves differently, but I wasn't aware of that when we specced out the project.

Aurora charges $0.20 per 1 million requests...your IO would have gotten expensive. It's also still stuck on PostgreSQL 11.9.

RDS can do up to 64K PIOPS these days. If you need more than that, I would definitely advocate for re-architecture to split things out and/or shard. We're up to 40k PIOPS in one of our larger databases and fast approaching the time to make that jump ourselves..
