CIOs have had a changing role for decades. Indeed, back when I was dealing with them as my bosses, they were mostly rotated in from the finance department and had no real technical skills to speak of.

These days, they typically have a technical background, but I wouldn’t call most of them technical or say they have a deep understanding of technology. Indeed, they were and mostly are political animals who understand that their career trajectory will be based more on who they know in the organization versus what they know. In short, I’ll never be a CIO.

But I may not want to be. As cloud computing continues to make its mark in the Global 2000, CIOs seem to be much less of a factor. Indeed, I’ve seen many of their roles diminish. Here are a few reasons why.

First, the corporate datacenters are shrinking, thanks to cloud computing. A CIO’s primary role was to keep those items running in many departments. Because the CIO had direct budgetary controls of where applications run in their companies, what got updated, and when, many departments thought they were being held hostage.
