At least that's the view of Nicholas Carr, who gave a talk at a one-day conference on cloud computing organized last week in London by Google. If you've read Carr's work in the past, his presentation will be familiar. One main point: the on-premise deployment of systems such as Oracle and SAP today are analogous to the on-premise factory power-plants of the 19th century--ultimately replaced by public electric utilities. So, it will be with utility computing.
Carr also gets a little bit into IT budget ratios, which we track closely at Computer Economics. His analysis is spot on and is a strong argument for why cloud computing ultimately will prevail over on-premise systems.
Near the end of the presentation, Carr presented five models for adoption of cloud computing:
- Internal clouds: large organizations take advantage of cloud computing technologies by moving their own large IT infrastructures to a cloud computing model.
- Cloud as supplement: organizations retain their on-premise systems but use cloud computing to deploy new IT capabilities.
- Cloud as replacement: organizations forgoing their own IT infrastructure altogether and going with cloud computing for everything. So far this is appealing, naturally, to smaller businesses.
- Cloud as democratizer: cloud computing allowing individuals to have their "own data centers," leading to an explosion in innovation.
- Cloud as revolution: cloud computing reducing the cost and increasing the accessibility of data processing, leading to new ways of embedding IT in new products and services.
What about the major on-premise software providers, such as SAP and Oracle? Can they make the transition to cloud computing? Although both SAP and Oracle have cloud computing initiatives, such as SAP's Business ByDesign and Oracle's On-Demand CRM, I'm not hopeful. They have too much invested in, and receive too much of their margin, from their legacy products.
Consistent with this view, at the end of his presentation, Carr looks at cloud computing as a disruptive technology, a la Clayton Christensen. I was glad to hear that, as I've long felt that cloud computing strongly qualifies as a disruptive technology that does not give hope to the current market leaders in enterprise software. But that's the subject for another post.
From time to time I bring up issues that buyers should be aware of in evaluating SaaS providers--for example, business continuity concerns. But in the long run, I'm convinced these issues will be worked through. The transition will take some time, but the economics are too strong for cloud computing not to prevail. Therefore, even today, buyers should consider every IT decision in light of the options available in the cloud.
Update, Nov 1. Be sure to read the first comment on this post, from former SAP executive Nenshad Bardoliwalla, who essentially confirms my point.
