The clearest example is mapping a RAID server (multiple disk drives, with some technique for splitting up the data to achieve high reliability) into a contract backed by multiple cloud computing providers. A 3rd party company could sell high reliability contracts by buying up cheap low reliability contracts and applying a RAID technique.
Cloud providers and hardware companies could also look at the price curve of different types of performance/reliability contractts in long term options contracts (eg. 1 hour of 1Ghz processor delivered 18 months from today) to plan for future demand.
It's a bit dated now, but I once took a stab at writing this up when I was trying to pick a startup idea. Amazon S3 came out shortly after this was written and changed the assumptions considerably: http://bit.ly/dWIpqC
