How about this: ACID RDBMS in many cases are sugar. That is, they provide very NICE features, but those features can be implemented in other ways. In the cloud world, the sugar may not be worth the costs. I think the weak case is much stronger than the strong case - that is, you can refactor to remove RDBMS dependencies; but that moves the complexity elsewhere.
