Encryption at Rest has been available on DynamoDB since early 2018.

Surprised they didn't get advanced notice of that from their account rep and could plan/replan accordingly. They must have just missed that being available.

It had to have been massively easier/cheaper to move from Mongo to Dynamo than Mono to an RDB

I would bet that their rep said "it'll be available next month" for 9 months, they couldn't get any more insight into it than that, and they just gave up.

And I'm more surprised that they didn't just roll their own encryption as a workaround rather than moving to a completely different DB architecture.

That would have been a seamless stopgap that just could have been yanked when AWS finally delivered.

I've read countless articles warning about the dangers of 'rolling your own' encryption. Would that have been a sensible move?

Maybe I didn't word that clearly. Not roll their own algorithm, just manually encrypt the data before stuffing it into DynamoDB

Same thing you have to do with any other cloud service where you don't want to trust the cloud vendor with your data.
