Some great analysis of IBM’s position with Red Hat.

This is the bet: while in the 1990s the complexity of the Internet made it difficult for businesses to go online, providing an opening for IBM to sell solutions, today IBM argues the reduction of cloud computing to three centralized providers makes businesses reluctant to commit to any one of them. IBM is betting it can again provide the solution, combining with Red Hat to build products that will seamlessly bridge private data centers and all of the public clouds.

Thompson has a great take on this.
