Don’t Let Your S3 Turn Into an Abandoned Warehouse. Your AWS S3 or any cloud-based file storage might look harmless at a glance. But files that “no one touches” could be quietly burning your budget 🫣
Today, K.Khun from our Platform Services Engineer team is here to spotlight a powerful (but often overlooked) tool from AWS: S3 Storage Lens and why it’s a must-have for every DevOps team.
What is S3 Storage Lens?
It’s a fully managed analytics tool for your S3 buckets, offering:
- An intuitive dashboard
- Granular, actionable metrics
- Real-world recommendations to help you take control
🚨 What can it help you with?
✅ Identify “cold” objects that haven’t been accessed in ages
✅ Check if your lifecycle policies are working as intended
✅ Detect unusual bucket growth and clean up precisely
✅ Filter by Region / Prefix / Storage Class — no scripts required
✅ Understand usage trends & behavior for smarter cleanup and archiving

🤔 When should you start using it?
💸 When your S3 bill keeps rising but you don’t know why
📊 When you’re tired of maintaining manual scripts just to monitor storage
🔍 When you suspect misconfigured or missing lifecycle policies

💡 TL;DR: AWS S3 Storage Lens = Your cloud’s surveillance system.
It helps DevOps teams stay ahead of usage behavior, reduce costs, and keep your S3 buckets clean and optimized before your cloud bill explodes.
