This is a super irritating feature of "enterprise" vendor pricing. What almost everyone on these platforms is doing is moving most of their bandwidth out of one of the CDN services (like say cloudfront) and then negotiating custom pricing on that bandwidth that is often as much as a full decimal place cheaper as long as you sign a couple grand a month yearly commit. There's still this massive massive pricing cusp between using the cloud as a utility and jumping into the suits & drinks & lunches sales guy game.
