I imagine it would take the CEO, with the backing of the Board of Directors, deciding the cloud services business is important enough to push through a massive overhaul of corporate culture, with the potential risk of disturbing their existing successful search and advertising business. It's the sort of thing that typically only happens when a corporation decides it has a huge problem; two historical cases that come to mind are Gerstner overhauling IBM in the face of the PC industry, and Satella overhauling Microsoft in the face of having missed smart phones and not wanting to miss cloud. I don't know whether Google thinks it has such a problem, or indeed whether I think it has, but I would expect such deep-rooted change in corporate culture to only happen in the face of such a decision.
