EDP Egress Concession
Egress discount inside EDP renewal. 30-60% off list is routine for committed customers with credible alternatives.
Data transfer is the most-negotiable line on the AWS bill — and the most-overlooked. This guide walks through egress, CloudFront, NAT Gateway, VPC endpoints, and the EDP levers that turn an unexamined cost into a negotiated one.
AWS networking costs aggregate across data transfer, dedicated network appliances, and content delivery. Most networking bills break down roughly as 50-65% data transfer (egress and cross-region), 20-30% NAT Gateway, 10-15% CloudFront, and the remainder in VPC endpoints, PrivateLink, Direct Connect, and Transit Gateway. The relative size depends entirely on workload mix — but for SaaS, media, and analytics workloads, egress alone can exceed every other AWS service line.
| Component | List Price (US-East-1) | Negotiability |
|---|---|---|
| Internet egress (first 10TB/mo) | $0.09/GB | High inside EDP |
| Internet egress (150TB+/mo) | $0.05/GB | High inside EDP |
| CloudFront egress (first 10TB/mo) | $0.085/GB | High via private pricing |
| NAT Gateway (hourly) | $0.045/hour | Low |
| NAT Gateway (data processed) | $0.045/GB | Low |
| Cross-AZ traffic | $0.01/GB each direction | Architectural, not negotiable |
| Cross-region traffic | $0.02-$0.09/GB | Moderate inside EDP |
| VPC Endpoints (interface) | $0.01/hour + $0.01/GB | Cheaper than the alternative |
| Transit Gateway | $0.05/hour per attachment + $0.02/GB | Low |
Internet egress at list pricing is one of the worst values in cloud computing — roughly 10x what Cloudflare and Bunny charge for equivalent delivery. AWS knows. Inside an EDP, egress is consistently negotiable to 30-60% off list with the right leverage and the right disclosure. The most reliable lever is a credible Azure or GCP proposal, paired with workload portability evidence. See our multi-cloud leverage service for the playbook.
The second lever is volume tiering. AWS will negotiate a higher volume tier transition than the published rate card — moving you to the $0.05 tier at 50TB instead of 150TB, for instance. This is a quieter ask than a percentage discount and is frequently granted to existing committed customers without much friction.
NAT Gateway pricing combines an hourly charge and a per-GB data-processing charge. For private-subnet workloads with high outbound traffic — typical for microservice estates pulling container images, third-party APIs, and S3 reads — the data-processing fee dominates. A single NAT Gateway processing 10TB/month costs $450/month in hourly fees plus $450/month in data processing. Most enterprise estates run multiple NAT Gateways per region; the cumulative spend is significant.
The mitigations are operational. VPC Gateway Endpoints for S3 and DynamoDB are free and remove that traffic from the NAT Gateway. VPC Interface Endpoints for other services cost more per hour but save the NAT data-processing fee on the affected traffic. Architecturally, route table audit and endpoint deployment usually reclaims 30-50% of NAT spend with no negotiation required.
CloudFront pricing is lower than direct S3 or EC2 egress for any cacheable content. For media, static asset, and API caching workloads, CloudFront in front of origin is almost always cheaper than direct egress. The bigger lever is the CloudFront Security Bundle (formerly the private pricing addendum), which is heavily negotiable for committed customers. We have repeatedly secured CloudFront pricing 35-55% below published.

Custom pricing addendum for high-volume CloudFront customers. Bundle with EDP for stacked discount.
S3 and DynamoDB Gateway Endpoints are free. Deploying them removes that traffic from NAT Gateway entirely.
Audit private-subnet traffic. Replace heavy NAT users with Interface Endpoints for AWS services. Significant per-region savings.
Cross-AZ traffic at $0.01/GB each direction adds up. Route same-AZ traffic same-AZ where latency allows.
For high-egress on-prem-to-AWS flows, Direct Connect data transfer is materially cheaper than internet egress.
500+ engagements. $340M+ client savings. We audit data transfer, push egress concessions inside EDPs, and architect NAT and VPC Endpoint patterns that reduce the bill structurally.
