An presentation from Bob Worrall, CIO at Sun, on the the future of the IT dept predicts that significant in house application development and hosting is finished as we all integrate Software as a Service (Saas) offerings from various 3rd party vendors. However, whilst we are seeing traction in this area, I have yet to see any significant architectural solution to handling the security and integrity of corporate and private data. Until that happens I can see that any significant adoption of SaaS across large enterprises will be a train wreck. Wait for the first scandals as organisations and individuals lost control of their data.
