I had the same latency concerns when I heard about this PaaS DB trend, but you’ll note that this runs in the AWS (soon GCP) region of your choice, so if you’re hosted there, it should be about the same latency as using their managed DB service.

If you aren’t hosting the app in the same AWS/GCP region then I still have the same question.

yes and no. In my AWS account I can explicitly pick an AZ (us-east-2a, us-east-2b or us-east-2c) but Availability Zones are not consistent between AWS accounts.

See https://docs.aws.amazon.com/ram/latest/userguide/working-wit...

But that's exactly why they introduced the AZ IDs (use1-az1 as opposed to us-east-1a), so you can tell whether you're really in the same zone, regardless of the name you see in a particular account.

Ah, thanks Internet stranger. TIL.
