On June 15, 2026 AWS made Console Private Access work without internet — VPC endpoints route 100% of browser traffic. First-party benchmark: 161 interface endpoints and ~$263/mo for a 12-service 3-AZ pilot in us-east-1.

NAT Gateways are one of the most silent budget killers on AWS. AWS finally added Compute Optimizer support to find idle ones — but the real fix is knowing when not to use them at all.

Data transfer is the most consistently underestimated cost in AWS architectures. It does not appear in compute estimates, it does not scale linearly, and it punishes microservices designs at exactly the moment growth feels like success.

A VPC misdesign at month two becomes a multi-quarter migration at year two. CIDR planning, subnet strategies, NAT gateways, VPC endpoints, Transit Gateway, and the network architecture patterns that scale without forcing a re-IP.
