Book excerpt: An accessible and comprehensive guide to the future of computing. Cloud Computing is the next computing revolution and will have as much impact on your life as the introduction of the PC. Using websites including Facebook, Flickr and Gmail, many people already store some information out in the Internet cloud. However, within a few years most computing applications will be accessed online with the web at the heart of everything we do. In this valuable guide, expert Christopher Barnatt explains how computing will rapidly become more reliable, less complex, and more environmentally friendly. He explores online software and hardware, and how it will alter our office work and personal lives. Individuals and companies are going to be released from the constraints of desktop computing and expensive corporate data centres. New services like augmented reality will also become available. Including coverage of Google Docs, Zoho, Microsoft Azure, Amazon EC2 and other key developments, this book is your essential guide to the cloud computing revolution.
