The world of enterprise IT is changing – from server to desktop and everywhere in between. You’ve heard the buzzwords: service architectures, loosely coupled applications, virtualisation, serialisation, network storage, network processing. These are just some of the ways in which the way we do IT are changing – a change that will have as much effect on the way businesses work as the arrival of the desktop PC.

I’m Simon Bisson, a technology journalist and consultant who’s been writing about enterprise IT issues for a long time now – and with the real world experience of designing and building large-scale loosely coupled systems: from telecom research labs to the early days of national ISPs, and from photo hosting platforms to telecom service platforms. It’s been a long road from the early ’90s to today – and a lot is happening around the world.
