I think that Windows Azure gives IT Pros, admins, etc, the opportunity to get involved with more interesting and higher value activities, such as capacity planning and forecasting, health monitoring, QA, etc, rather than the lower level stuff that is needed just to keep systems up and going
I can imagine an insurance market will emerge to support businesses where the value of the data or up time is high.
An analogy would be: If I take a train to the airport and the train breaks down, and as a result I miss the flight and my holiday is ruined, would I expect to sue the rail company for the loss of the holiday? Of course not! I am just one of a number of fee paying passengers on that journey and my travel is not intrinsically my important than anyone else’s on that train. The answer is I buy holiday insurance to cover such eventualities.
