What it shows

  • NAT Gateways charge $0.045/GB simply for bytes flowing out to AWS services.
  • S3 and DynamoDB Gateway Endpoints are completely free of charge.
  • Interface Endpoints keep high-volume API traffic entirely inside AWS network.

The takeaway

Gateway VPC Endpoints for S3 and DynamoDB cost zero and eliminate thousands in NAT processing fees.
