This article taught me how to cut AWS S3 storage costs by using the right storage classes, setting up lifecycle policies, and regularly checking usage with tools like Storage Lens. It explains how moving old or rarely used data to cheaper classes like Glacier saves a lot, but warns about hidden fees and issues with small files. Automating data movement and deleting unused files are key tips. The author also shows how tracking costs by project helps everyone stay aware. I found this article very helpful, practical, and easy to follow for anyone wanting to save money on AWS storage.
