This article showed me the best ways to cut hidden AWS S3 costs. It compared tools like reCost.io for full automation, AWS S3 Lifecycle Policies for native rule management, and open-source options like S3Stats and aws-cost-saver for more control. The author tested each tool in real AWS setups and explained what worked best for different needs, from simple automation to deep analytics. I liked how clear and practical the advice was. This article is a great guide if you want to save money on S3 and pick the right tool for your team.
