When you’re operating at scale, pushing the needle means a complex,
coordinated dance of well-applied technologies, development
techniques, statistical analyses, intra-organizational communication,
judicious engineering management, speedy and reliable
operationalization of hardware and software, vigilant monitoring, and
so forth. Scaling is hard. So hard, in fact, that the ability
to scale is a deep competitive advantage of the sort that you can’t
simply go out and download, copy, purchase, or steal.
