The world seems to get smaller every day, closing in on the concept of the “global village” put forward by Wyndham Lewis in 1948. Already, over 1 billion people are effectively connected via devices attached to mainly open networks enabling them to exchange information in ways that would have been unthinkable 30 years ago. And now, we have cloud computing. Although it’s not a new idea, it has taken a while for standards, infrastructure and interest to meet, creating the perfect storm to make the idea technically and commercially viable. It has arrived, and the amount of interest from both vendors and users is considerable.
