the most common reason a nat gateway bill creeps: s3 reads from private subnets going out through nat at $0.045/GB.
the fix is free and almost nobody does it first. gateway endpoints for s3 and dynamodb cost nothing — no hourly fee, no per-GB fee. you add a route, and that traffic goes over a private aws path instead of through the meter. it never touches nat again.
do this before anything fancier. most teams never need to go further.
