Public Internet Egress Costs: AWS vs Azure vs GCP vs Hetzner Comparison
Egress costs out of control? Many companies underestimate the cost of outbound internet traffic. With our migration framework, we show you how to save up to 95% on traffic costs. Request free analysis now
Public Internet Egress – traffic leaving your cloud to the internet – is one of the most underestimated cost factors in the cloud. User downloads, API responses, file transfers: all of this costs real money with the major hyperscalers.
In this article, we compare the egress costs of AWS, Azure and GCP and show why Hetzner is the significantly cheaper alternative for many workloads.

What is Public Internet Egress?
Public Internet Egress = Traffic leaving your cloud to the internet.
This includes:
- User downloads (files, images, videos)
- API responses to external clients
- Files from Object Storage to end users
- Backup transfers to external systems
Not included: Traffic between regions/zones/VPCs or provider-internal traffic – these are separate cost items.
Egress Costs Overview
AWS (Data Transfer Out to Internet)
| Volume | Price per GB |
|---|---|
| First 100 GB/month | Free |
| Up to 10 TB | $0.09/GB |
| 10–50 TB | $0.085/GB |
| 50–150 TB | $0.07/GB |
| From 150 TB | $0.05/GB |

Azure (Bandwidth - Internet Egress)
| Volume | Price per GB |
|---|---|
| First 100 GB/month | Free |
| Up to 10 TB | $0.087/GB |
| 10–50 TB | $0.083/GB |
| 50–150 TB | $0.07/GB |

GCP (Internet Data Transfer - Premium Tier)
| Volume | Price per GiB |
|---|---|
| 0–1 GiB/month | Free |
| 1–1,024 GiB | $0.12/GiB |
| 1–10 TiB | $0.11/GiB |
| From 10 TiB | $0.085/GiB |
Note: GCP calculates in GiB (1 GiB = 1,073,741,824 Bytes), not GB!

Hetzner (Traffic)
| Volume | Price |
|---|---|
| 20 TB included | €0 |
| Each additional TB | €1.19/TB |
Important: Hetzner only counts outgoing traffic. Incoming and internal traffic are free.

Calculation Examples: 1 TB, 10 TB, 50 TB
Example 1: 1 TB Egress per Month
| Provider | Cost/Month |
|---|---|
| AWS | ~$82 (900 GB × $0.09) |
| Azure | ~$78 (900 GB × $0.087) |
| GCP | ~$110 (1,000 GiB × $0.11) |
| Hetzner | €0 (included) |
Savings with Hetzner: 100%
Example 2: 10 TB Egress per Month
| Provider | Cost/Month |
|---|---|
| AWS | ~$900 |
| Azure | ~$870 |
| GCP | ~$1,100 |
| Hetzner | €0 (included) |
Savings with Hetzner: 100%
Example 3: 50 TB Egress per Month
| Provider | Cost/Month |
|---|---|
| AWS | ~$4,165 |
| Azure | ~$4,015 |
| GCP | ~$4,700 |
| Hetzner | ~€36 (30 TB overage × €1.19) |
Savings with Hetzner: over 99%
Why Hetzner is So Affordable
The price differences have several reasons:
1. Business Model
Hyperscalers deliberately profit from egress – it's a profit center. Hetzner calculates traffic as operating costs.
2. Infrastructure Ownership
Hetzner operates its own data centers and network infrastructure in Germany and Finland. No margin for third parties.
3. No Vendor Lock-in Incentive
At AWS/Azure/GCP, ingress is free, egress is expensive – making switching harder. Hetzner doesn't have this interest.
4. Focus on Europe
Less global edge network means lower infrastructure costs passed on to customers.
How to Reduce Egress Costs?
Regardless of provider, there are strategies to reduce egress:
- Use CDN – CloudFlare, Bunny.net or Hetzner's own CDN
- Enable compression – gzip/brotli for API responses
- Optimize caching – Browser and edge caching
- Avoid bulk downloads – Streaming instead of full downloads
- Switch providers – Migrate to Hetzner for traffic-intensive workloads
Conclusion
The egress costs of major hyperscalers can quickly reach thousands of euros per month for traffic-intensive applications. Hetzner offers a dramatically cheaper alternative with 20 TB included traffic and €1.19/TB overage.
For workloads with high outbound traffic (APIs, file sharing, streaming, downloads), switching to Hetzner can reduce monthly costs by 95%+.
