Yeah, do not do this. You'll end up with a $1000 bill from Amazon becuase you forgot to shut it down and discover very quickly they don't care at all once they already have your money.
I dunno if they'd eat that cost again, and I wouldn't try it on purpose.
But keep in mind that they have an incentive to do this: it's the cost of acquiring users without scaring them about a possibly humongous bill.
I now have better billing alarms set.
Under section 4, anyone can set up an aws cost budget
It seems to follow their practice of building the “API first” solution. By the way, a lambda/programmatic solution allows you to disable lower priority resources and retain higher priority resources. It’s a lot of effort, but it’s incredibly flexible.
That hasn't been my experience with AWS but then again it has been years since I allowed such a thing to happen.
