Cloud Computing Drivers - Where is the Focus?

While I was writing this post about the linkage between vendor offerings and IT offerings, I started noodling on this circular challenge:

Public Cloud Driver - IT People (dissatisfaction with IT services)
Public Cloud Enemy - AWS Outages

Private Cloud Driver - IT Competitiveness (business demands for better services)
Private Cloud Enemy - IT People

Lots of time and effort gets spent trying to debate the merits or failings of various technologies. Are technologists really spending their time on the right things? Maybe this is why Gartner has recently flip-flopped on their Public vs. Private Cloud deployment guidance. But which group within the business will be leading that leap?
