Although cloud hosting has been a massive boom it’s not necessarily a disruptive technology model.
While Amazon is certainly doing it to a much larger scale than ever before, it more represents an ongoing maturity of the simple web hosting we began in the early 90s. It may now be on steroids but it’s still fundamentally the same virtualized shared infrastructure model.
It’s also still just a technical decision, not one of business transformation. The Marketing and other business managers don’t care whether an app is run in-house, in the Cloud or anywhere else, as along as it works and provides them the software functionality they need.
So it is usually the technical teams making these decisions , with no real impact on how the organization overall performs their work, or in how the software that it runs works in terms of information models.
