All the barriers to cloud computing are not merely technology related. Google's video here takes you to a bit of human history and addresses CIOs and CTOs on how human evolution is based on giving up control to get greater control. Watch this video to see how Google does this beautifully using human history and right analogies to drive home the point. Also a great stuff for education institutions on how they can start collaborating from within. I hope the Indian universities are taking note of this.
