S3 Cost Analysis Script
Python script breaking down S3 costs per bucket: storage class distribution, request costs, data transfer, and lifecycle rule recommendations.
S3 Cost Analysis Script
S3 costs creep up because most teams never look at them closely. This script breaks down your S3 spend bucket-by-bucket: how much is Standard vs Infrequent Access vs Glacier, what you are paying in request and retrieval fees, and exactly which lifecycle rules to add to cut your bill.
What Is Included
A Python script that reads CloudWatch Storage Metrics and Cost Explorer data to build a per-bucket cost profile. It then compares each bucket against lifecycle best practices and outputs specific rule recommendations — with the estimated savings from each change.
Developer Experience
- Minimal setup — configure your AWS profile and run
- Human-readable output plus optional JSON export
- Lifecycle recommendations formatted as ready-to-paste CLI commands
