I'll let you read the article at your leisure but I'll sum it up by saying that it recommends that IT is best seen as a fellow Business Unit within an organization rather than simply as a supplier of charge-back services. One example is the difficulty of 'selling' the company standard laptop to a business unit for $800 when they can get an equivalent-spec laptop from the local YumCha computer
So what does this have to do with the Cloud?
I must admit that I've been seeing the Cloud as the thin edge of an outsourcing wedge which would lead to the dumbing down of IT as it was forced to abandon user requirements to meet the packaged services provided by the vendors. However if your IT department is a Business PARTNER with the other units of the company, then it can pick and choose what aspects of the Cloud work best for the organizational IT strategy rather than the only issue being that its internal chargeback costs are more expensive than the Cloud environment.
I still believe there will be Blood on the Floor when the Cloud hits its first major security breach, but perhaps moving away from the 'IT as a Cost Center' mindset will make the Cloud a more attractive proposition.
