How Cloud Egress & Bandwidth Pricing Works
Major hyperscale cloud providers (AWS, Google Cloud, Microsoft Azure) charge substantial fees for data leaving their networks to the public internet—commonly known as Data Transfer Out (DTO) or Egress. While ingesting data into the cloud is almost always free, egress pricing acts as a significant operational expense and vendor lock-in barrier.
Standard Tiered Pricing Schedules (North America / Europe)
- Amazon Web Services (AWS): First 100 GB/mo free. Up to 10 TB: $0.09/GB ($90/TB). Next 40 TB: $0.085/GB ($85/TB). Next 100 TB: $0.07/GB ($70/TB). Over 150 TB: $0.05/GB ($50/TB).
- Google Cloud (GCP Premium Tier): First 200 GB/mo free (Standard). 0–1 TB: $0.12/GB ($120/TB). 1–10 TB: $0.11/GB ($110/TB). 10–50 TB: $0.08/GB ($80/TB). 50 TB+: $0.08/GB.
- Microsoft Azure: First 100 GB/mo free. 100 GB–10 TB: $0.087/GB ($87/TB). 10–50 TB: $0.083/GB ($83/TB). 50–150 TB: $0.07/GB ($70/TB).
- Cloudflare (CDN / R2 / Bandwidth Alliance): $0.00 egress fees across all data volumes.
How Routing Through Cloudflare Eliminates Egress
By placing Cloudflare CDN or Cloudflare R2 object storage in front of cloud origin servers, high cache-hit ratios (typically 80%–95%) drastically reduce the volume of outbound data fetched from AWS, GCP, or Azure, yielding thousands of dollars in annual savings.
Frequently Asked Questions
Why does Cloudflare offer zero egress fees?
Cloudflare co-locates extensive interconnection peering with Internet Service Providers (ISPs) and founded the Bandwidth Alliance to reduce interconnection markups. Cloudflare R2 object storage eliminates data egress charges completely as a competitive differentiator against Amazon S3.
Are egress rates higher in Asia Pacific or South America?
Yes. Cloud data transfer rates in regions like São Paulo (South America) or Sydney/Tokyo (APAC) are typically 25% to 80% higher than North American and European standard tiers due to undersea cable transit expenses.
What is the difference between AWS CloudFront and EC2 egress?
Both CloudFront and EC2 provide the first 100 GB/month free. Beyond that, CloudFront CDN egress pricing starts at $0.085/GB, slightly lower than direct EC2 internet egress ($0.09/GB).
