S3 Bucket Sizes

Amazon S3 buckets are essential for object storage, but without visibility into bucket sizes and storage distribution, organizations can accumulate significant expenses over time.

Implementation Effort: Medium - Estimated time: 2-4 hours. Requires analysis of access patterns and implementation of lifecycle policies or storage class transitions.

What We Detect

• Largest buckets -- Your top buckets by storage size with cost breakdown
• Storage class distribution -- How data is spread across Standard, Intelligent-Tiering, Glacier, and other storage classes
• Optimization opportunities -- Buckets where lifecycle policies or storage class transitions could reduce costs

Why It Matters

S3 Standard storage costs $0.023/GB-month, while Glacier Deep Archive costs $0.00099/GB-month -- a 96% reduction. Many organizations store infrequently accessed data in Standard without realizing the savings available from tiering.

Recommendations

1. Implement lifecycle policies to automatically transition or expire objects
2. Enable S3 Intelligent-Tiering for buckets with unpredictable access patterns
3. Move cold data to Glacier or Deep Archive for long-term retention
4. Clean up unused data that accumulates over time
