Azure positions Microsoft reasonably well to maintain its enterprise accounts. However, young Web-based companies generally do not use Microsoft products and services because they are too expensive. They prefer Linux and other free open source products, or hosting via Amazon, Google, and others. This preference does not bode well for Microsoft. The startup firms of today will become the larger customers of the future and, in general, they are not Microsoft customers.
