I was pleased to see that Newsweek ranked Nick Carr’s The Big Switch No. 4 in its recent list of “50 Books for Our Times.” Say what you will about Carr’s somewhat utopian vision of a completely on-demand, in-the-cloud computing future, but the book sparked a deep discussion about what has come to be known as cloud computing, and it continues to do so. And based a discussion I had with Carr after the book was released, his predictions seem to be coming true. He never suggested an overnight revolution, but rather a decades-long evolutionary process wherein private-cloud use would precede public-cloud use and small-scale use would would precede large-scale use. A year and a half later, we’re making pretty good progress.
