This is exactly the kind of practical automation every AWS user needs! I’ve seen so many teams struggle with runaway EC2 costs just because instances stayed running longer than needed. Moving from hardcoded instance IDs to tag-based management is such a game-changer it scales beautifully and saves tons of maintenance effort.

Also, emphasizing professional logging and error handling makes this approach production-ready, not just a quick hack. The step-by-step guide is super clear for anyone looking to implement this ASAP.

Thanks for sharing such a well-structured, real-world solution! Looking forward to trying this out and seeing how much cost and time it saves.
