Nicholas Carr's vision of cloud computing

By Nora Young, host of CBC radio's Spark

"Cloud computing" is a buzz term in tech circles these days. It refers to the move from computing as something that happens on the hard drive of your computer - with software you've loaded onto it - to computing done remotely on a grid of computers, with software accessed online.

You're likely already using 'the cloud' if you use web-based e-mail, or have a profile on a social networking site. Imagine a future where all your data - not just your Facebook profile - lives online.

In his new book, The Big Switch: Rewiring the World, from Edison to Google, Nicholas Carr looks ahead to the seismic shifts this move to cloud computing may bring with it, raising questions about security, privacy, and economics.
