I read The Big Switch: Rewiring the World from “Edison” to “Google” 4 years ago.
4 years is an eternity in tech world, but this book is still worth reading.
The author, Nicollas Carr make a very interesting parrallel between electrification and change occuring in IT world.
I use what I’ve read there everytime I need to explain someone what cloud computing is about.
Carr also discuss all the impact that this change in IT have on our day to day life.
If you’re interested in IT move to the cloud, you should read this book.
