With AWS, you can set up billing rules to notify you of any charges over any limit you want, and you can break that down by service or overall charges, etc…. You learn a lot about this process when you become an AWS Certified Cloud Practitioner.

Sadly, they don’t turn these things on by default. You have to know about them in advance, and you have to know how to configure them. That’s one thing I wish they would improve.
