May I ask: what's your opinion on the TCO of "lots of little boxes" vs Big Iron, especially in terms of energy consumption and maintenance?
This depends on your specific situation and the specific application and hardware in question. Where we have replaced big iron with lots of little boxes, the total Electricity consumption was about the same. But that was mostly because of age. Newer machines do more per watt consumed.
The savings come from increased reliability and reduced hardware cost. I.e. The Million Dollar Sun box mentioned in my initial post would be replaced by about a dozen $5,000 Dell Servers. This won't happen anytime soon however as the software is not written for the cloud and porting it is none trivial.
... I doubt they lose that much money in early termination due to deceased individuals.
For the record they do loose that much money. If you got a top end phone for "free" with your contract, it cost the phone company the full wholesale price.
