Oracle Cloud
$0.0085 /GBStrengths · 10TB/month free egress (100x AWS/Azure/GCP), flat $0.0085/GB after free tier, extremely competitive pricing.
Weaknesses · Smaller ecosystem, fewer regions, less community support, concerns about long-term pricing stability.
Best for · Cost-sensitive workloads, Oracle database shops, organisations looking to minimize egress costs with a traditional cloud.
Backblaze B2
$0.01 /GBStrengths · Free egress via Cloudflare Bandwidth Alliance, simple pricing, reliable storage, good S3 compatibility.
Weaknesses · Limited to object storage, no compute services, fewer regions, smaller scale than hyperscalers.
Best for · Backup and archive storage, media assets served via Cloudflare, cost-sensitive storage workloads.
DigitalOcean
$0.01 /GB overageStrengths · Generous bandwidth included with droplets (1-10TB), simple pricing model, developer-friendly platform.
Weaknesses · Limited enterprise features, fewer regions, bandwidth included varies by droplet size, less cost-effective at very high volumes.
Best for · Startups, small-to-medium workloads, developers who want simple, predictable pricing.
Hetzner
~$0.001 /GB overageStrengths · 20TB+ included per server, cheapest overage rates in the industry, excellent price-to-performance ratio, EU-based.
Weaknesses · Limited to EU and US regions, fewer managed services, less automation tooling, no global CDN.
Best for · European workloads, high-bandwidth applications, teams comfortable managing infrastructure, budget-constrained projects.
[02]Free tier comparison
Free allowances vary dramatically and can flip the cheapest-provider result for smaller workloads.
| Provider | Free egress | Notes |
|---|---|---|
| Oracle Cloud | 10 TB / mo | Most generous free tier among traditional clouds. Always-free, not trial. |
| Cloudflare R2 | Unlimited | Zero egress fees. Pay only for storage and operations. |
| AWS | 100 GB / mo | Aggregated across all services and regions. Always available. |
| Azure | 100 GB / mo | Zone 1 pricing. Same as AWS free tier amount. |
| GCP | 100 GB / mo | Plus free cross-zone traffic within same region. |
| Backblaze B2 | 3x storage | Free egress = 3x stored data. Free via Cloudflare Bandwidth Alliance. |
Methodology
How we source these numbers
All pricing data on this page is sourced directly from official cloud provider pricing documentation. We verify all rates monthly and update this page accordingly. The comparison uses standard internet egress rates from US regions (or Zone 1 equivalent) with free tier allowances deducted. Regional pricing variations may apply for non-US regions.
Hidden costs such as NAT Gateway processing, cross-AZ transfer, and load balancer fees are not included in the comparison table above, as these vary by architecture. For a complete cost picture including hidden charges, see our hidden costs guide.

[03]Frequently asked
Q.01What is the cheapest cloud provider for egress?
›
Cloudflare R2 charges zero egress fees, making it the cheapest for any data-transfer-heavy workload. Among hyperscalers, Azure is the cheapest below 50TB per month at $0.087/GB versus AWS at $0.09/GB and GCP at $0.12/GB; from 50TB up, Azure and AWS rates are identical ($0.07/GB, then $0.05/GB above 150TB). Oracle Cloud offers 10TB free and $0.0085/GB after that. For pure cost optimization, Hetzner has the lowest overage rates at approximately $0.001/GB.
Q.02Is GCP egress cheaper than AWS?
›
GCP Premium Tier egress is more expensive than AWS at all volume levels ($0.12/GB vs $0.09/GB for the first tier). However, GCP Standard Tier at $0.085/GB is slightly cheaper than AWS and comparable to Azure. The key GCP advantage is free cross-zone traffic within the same region, which eliminates the $0.01/GB cross-AZ charges that AWS imposes. For architectures with heavy internal traffic, GCP can be cheaper overall despite higher internet egress rates.
Q.03How much does cloud egress vary between providers?
›
Cloud egress costs vary by up to 127x between providers. At the extremes, Cloudflare R2 charges $0.00/GB while GCP Premium Tier charges $0.12/GB. Among alternatives, Hetzner charges approximately $0.001/GB for overage traffic while including 20TB+ free per server. The variation is even greater when you factor in free tier allowances: Oracle Cloud gives 10TB/month free while some providers offer no free tier at all. The right choice depends entirely on your volume and architecture.
Q.04Should I use multiple cloud providers to save on egress?
›
A multi-provider strategy can reduce egress costs significantly. The most common approach is storing egress-heavy data on Cloudflare R2 or Backblaze B2 while keeping compute on AWS, Azure, or GCP. This works well because R2 uses the S3 API, making migration straightforward. However, cross-cloud data transfer still incurs costs on the sending provider, so the architecture needs careful planning. For most organisations, the biggest wins come from optimizing within a single provider first.
Q.05Do all cloud providers offer free egress tiers?
›
Most major providers offer some free egress. AWS and Azure provide 100GB per month free. GCP is less generous on its default Premium Tier (1 GiB free) but gives 200 GiB free on Standard Tier networking. Oracle Cloud offers a generous 10TB per month free, which is 100x more than the other hyperscalers. Cloudflare R2 has unlimited free egress. Backblaze B2 provides free egress equal to 3x your average monthly storage. DigitalOcean and Hetzner include generous bandwidth allowances with their servers rather than charging per-GB egress.
