By saying yesterday that the cloud is removing IT's control over its own technology and IT is helping by stonewalling business managers until they go around it, I wasn't saying cloud technology itself is pushing IT into more marginal roles.
IT is doing that itself, by not staying ahead of the needs of the user base and figuring out ways to deliver the cloud functions users need without losing the mechanisms of control that IT and corporate governors also need.
Part of the reason is that management tools and platforms aren't advanced enough to provide solid, granular monitoring and management of virtual and cloudish assets on many different platforms.
The rest of the reason is that IT managers are better at reconfiguring systems than organizations.
Consumerization of IT became a big deal because non-IT departments changed the way they did things to take advantage of the capabilities of smartphones, tablets and the cloud.
IT-icization of the cloud is being held back by IT's inability to adapt itself that quickly.
Carr is right that IT doesn't matter from a competitive standpoint, if your company uses the same tech everyone else does.
The uniqueness, the competitive advantage available from technology sometimes comes from IT so new and smart no one else can make it work yet.
More often it comes from a combination of slightly advanced technology whose effect is multiplied by good strategic planning from both business and IT to make sure the organization can change to take the greatest advantage of some shiny new thing.
So far – at least when it comes to cloud – IT's efforts and organization haven't caught up to the potential of the systems it is building.
