A detailed financial comparison between the AWS S3/CloudFront approach and the Cloudflare R2 zero-egress model. Real production numbers from running both stacks in parallel.
Status
This analysis is currently in the data collection phase. We are running both architectures in parallel to gather real-world cost metrics over a full billing cycle.
Expected publication: Q2 2026
What We’ll Cover
- Side-by-side cost comparison with real invoices
- Egress cost impact at different traffic levels
- Performance benchmarks (TTFB, cache hit ratios)
- Migration complexity and hidden costs
- Break-even analysis: when does each approach win?
Preliminary Findings
Early data suggests a ~90% cost reduction when migrating from AWS CloudFront + S3 to Cloudflare R2 for static content delivery. The primary driver is the elimination of egress fees.
Stay tuned for the full analysis with production data.
