Book excerpt: Both enterprise and consumer cloud adoption will lead the market into new realms. From the “cloud to the ground,” each chapter of our ebook looks back at the short history of cloud computing from the early stages of far off clouds, through the gathering clouds that turned into fog. Today that fog is shifting, and beginning to rain down the first drops of change. We sifted through our blog posts from 2006 onward to present a reflection of our thoughts at the time. Interspersed with each chapter are new, exclusive insights from friends, colleagues, and customers we met along the journey. Big thanks to our contributors: Fred Hoch, Edmund Sutcliffe, Krishnan Subramanian, James Elwood, Chad Lawler, and Patricia Seybold. Thank you to those who gladly let us share their works from over the years: Jeff Barr, Eric Knorr, James Governor, Chris Purrington, Chris Hoff, and Chris Swan.
