| Hidden Overage Trap | S3 and DynamoDB traffic routed through Managed NAT Gateways incurs $0.045/GB processing fee unnecessarily when free VPC Gateway Endpoints are not configured. | Continuous Cloud Backup snapshot retention and cross-region data transfer fees often equal 35%–50% of the underlying compute cluster bill. |
| Primary Negotiation Lever | Attach free S3/DynamoDB VPC Gateway Endpoints immediately (cuts NAT data bill 40%–70% in 10 minutes) and bundle remaining egress into an AWS EDP addendum. | Purchase annual Atlas Credits through AWS/GCP Marketplace to burn down existing cloud commits while negotiating an 18%–24% volume discount. |
