Jeff Jonas of IBM doesn't recommend batch systems such as Hadoop (http://jeffjonas.typepad.com/jeff_jonas/2011/04/the-data-is-..., http://techcrunch.com/2010/10/27/big-data/) for real-time context accumulation systems. I have heard that IBM is making use of topological embedding algorithms to build distributed graph databases capable of real-time analysis, but very little of that research is public.

While Amazon's announcement is great news for Hadoop users, I do think the future is in these real-time systems. However there isn't a clear winner yet, so it is appropriate that AWS is yet to bundle one up as an offering.
