Among the Big Three
- Azure is cheapest at scale, reaching $0.04/GB at 50TB
- AWS offers the most predictable tiering with aggressive volume discounts
- GCP is most expensive at entry but offers Standard Tier as a cost lever
- At 100TB/mo, Azure saves $2,072/mo vs AWS and $2,321/mo vs GCP
Zero-Egress Alternatives
- Cloudflare R2 is the standout: S3-compatible API with zero egress fees
- Wasabi offers zero egress with a minimum storage retention requirement
- Backblaze B2 charges $0.01/GB but is free via Cloudflare CDN
- A team spending $4,000/mo on S3 egress saves $48,000/year by switching to R2

Frequently Asked Questions
Which cloud provider has the cheapest egress?
Cloudflare R2, Wasabi, and Backblaze B2 all offer zero or near-zero egress fees. Among the big three, Azure is cheapest at scale ($0.04/GB at 50TB+), AWS is mid-range ($0.05/GB at 150TB+), and GCP is most expensive at entry level ($0.12/GB) but competitive at volume.
How much does 10TB of egress cost on each cloud provider?
At 10TB/month: AWS costs approximately $912 (tiered from $0.09/GB), Azure costs $868 (tiered from $0.087/GB), GCP costs $1,221 (tiered from $0.12/GB), Backblaze B2 costs $102 ($0.01/GB), and Cloudflare R2 and Wasabi cost $0.
Is Cloudflare R2 really free for egress?
Yes. Cloudflare R2 charges zero egress fees for data read from storage. You pay only for storage ($0.015/GB/month) and class A/B operations. This makes R2 dramatically cheaper than S3, Azure Blob, or GCS for egress-heavy workloads.
At what volume does AWS become cheaper than GCP?
AWS is cheaper than GCP Premium Tier at all volumes because AWS starts at $0.09/GB versus GCP's $0.12/GB. However, GCP Standard Tier ($0.085/GB) is competitive with both AWS and Azure at lower volumes. At 10TB+, GCP Standard Tier drops to $0.05/GB.
