Common Mistakes to Avoid

❌ Egress fees are often underestimated

AWS charges $0.09/GB for data out. 10 TB out/month = $921 egress fee — often more than storage itself.

❌ Multi-region replication doubles cost

Replicating across AWS regions costs 2× storage plus cross-region transfer fees.

Frequently Asked Questions

AWS S3 Standard: $0.023/GB. Azure Blob LRS: $0.018. GCS Standard: $0.020. Backblaze B2: $0.006. S3 Glacier: $0.004.

When is cloud storage cheapest?

Cold archive tier (Glacier, Azure Cool) for data accessed rarely. B2 and Wasabi for frequently accessed data. S3 Standard for high-performance workloads.

Reduce egress costs?

CDN in front of S3. Serve from region closest to users. Compress data. Cache aggressively. Consider Cloudflare R2 (zero egress fees).
