I was talking to a colleague who works for a large technology vendor. His company offers products to enable IT organizations to construct cloud infrastructures inside their own data centers - to turn existing stable, static computing environments into ones that support scalability, agility, and dynamic applications. The company's progress on its products has been impressive, early implementations successful, and interest from their customer base (infrastructure groups within large IT organizations) high. However, he shared an apprehension with me regarding product adoption. "I'm concerned that while our customers are working on a very deliberate plan that will take a couple of years - doing their research, performing a pilot, evaluating the economics, making the capital investment business case - that the apps side of the house will just charge ahead using on-demand public cloud providers like Amazon." While he was worried about this trend from the point of view of how it will affect the prospects for his company's products, my mind moved toward a different outcome: the boomerang.
