I can definitely imagine the savings in IT support of a larger cluster, much like internet host providers parse out domains/hosting profitably. The effect of adding a control dial on spending versus bandwidth/processing power/storage for unknowns will allow for greater market experimentation with lower long term costs. Once past the acceptance/trust boundaries, I can’t help but imagine cloud computing as an efficiency boosting service.
Are there similar cloud concepts for software development? What about in other industries like power control or manufacturing/fulfillment?
