How do you cut EC2 costs for workloads that sit idle nights and weekends, without relying on someone remembering to turn things off?
Automate the stop and start instead of asking anyone to remember it.

Either way, tag-based scoping is what keeps it from ever touching something that shouldn't be stopped.
