The document discusses how cloud computing adoption within organizations is often bottom-up, starting with individual developers and departments adopting public cloud services on their own before IT leadership is aware. It cites surveys that found the majority of initial cloud computing decisions were made by developers and line-of-business units, not CIOs. This bottom-up adoption pattern is similar to what happened previously with open source software. The document advises enterprises to embrace and manage this bottom-up trend, while vendors should plan sales strategies around it.
