I've been using the evolution of water supply as an analogy for the evolution of computing platforms for some time now. As
part of an internal event this month, we had this animation produced and I thought it was worth sharing.
It's an analogy . Of course, maybe he didn't have the capacity to catch enough rain, or it was contaminated some how, or whatever ...
That's a great analogy and an entertaining story.
The only thing I'd point out is that it's always been the women who have to carry the water. I just got back from visiting a remote school in Kenya, where they've put in an Aussie windmill. Many women and children still carry water in big containers on
their heads up to seven or eight kilometers every day!
One of the changes coming with cloud computing is that it has to be simpler than an internal solution, such as SBS, is currently. Maybe the point could be (in your analogy) that when the source of water is further away (ie more difficult) you will be more
likely to employ an external resource!
