“secret weapon” (IT Jargon): It’s actually not secret, nor unheard of, but only feasible in extreme edge cases or at huge scale.
Yeah, more like “Amazon Web Services' secret weapon: Economies of scale and bags of money”.
Well, and, to be fair, there’s some honest to god interesting innovation going on there too. It’s true, most companies wouldn’t be ABLE to do this kind of custom design even if they wanted to, but that doesn’t lessen the achievement of the peeps involved IMO.
(I work for AWS but not for that group and honestly am in awe of some of what they’ve accomplished.)
