Seems to me as if this change in emphasis is just a stepping stone to a different architecture altogether. Anyone else see the irony in decentralising data centres? Personally, I suspect that, as soon as everyone's comfortable with data centres being largely geography independent, they'll quickly move on to stopping bothering with data centres at all, though I'm not sure how that'll translate in practical implementations.
That said, cleverer people than me have been embarrassingly wrong in their predictions of the future, so I may well be way off the mark - albeit less embarrassed to be so.
