If you think that either Azure or AWS loop terabits of customer traffic between two of their own services "out to the Internet" and back just because the IPv4 octets don't start with a "10", then you're the one who's missing the big picture.
Yep. Pick your poison. You're either nickle-and-dimed for a "NAT gateway" or overpaying for "VPC endpoints". Often, it's both. I preferred the EC2-classic days, honestly.
