Each AWS service call from private subnets could be adding unnecessary NAT Gateway charges ($0.045/GB) on top of standard data transfer fees. With 50TB monthly traffic, that's $2,250 in avoidable costs. Analysis of how VPC endpoints eliminate this double-charging, with performance implications and implementation patterns.

I am not paying anything for AWS anything, exactly because of this in transparency.

Is it that modern language stacks scale so badly that you actually need all that AWS overhead?
