> it doesn’t get shut off nightly when the RDS systems do to save money

If your company needs to shutdown RDS to save a couple of bucks a month, there's a much larger problem at hand than RDS vs Dynamo.

At scale it’s a little bit more than a few bucks. Across the board, we spend hundreds of thousands on ec2 instances for dev/test, so turning them off at night when nobody uses them saves you quite a lot of money.
