IT is a fashion industry, and cloud computing is the new black. Currently at the height of its hype, it will suffer a backlash before becoming fully mainstream and established, by which time a new phrase will have captured the imagination of IT pundits. Some fashions are longer lasting than others. Cloud computing as a term may have a use-by date, but the technical, operational, and commercial innovations behind it are here to stay. Cloud computing is a real innovation in the logic of how IT is sourced and managed and how services are delivered, and its use will grow steadily over the next 12 months. It is no longer a question of whether or not enterprises will use cloud computing, they already are.
