The egress section is the one I would put first for any startup, because it is the only cost that grows with success and also with leaving. A useful habit is to tag every bucket and load balancer by feature from day one, so when the bill doubles you can see which feature did it instead of arguing about it in a meeting. Have you seen startups actually negotiate egress down, or is moving traffic behind a CDN still the only lever that works?
