For those of us getting into amazon’s Elastic Compute Cloud (ec2), this is a really cool idea.  The idea is that your load grows and a new node is ready to handle additional capacity.  Once load lessens, boxes are turned off.  Integrating this with box stats, response times, monitoring per service makes sense.

I wanted everyone to be thinking of the consumable computing model.  Pay as you go for what you use is really attractive.  No more do you have to have 10 boxes in your www cluster all day long if your spike is only during 8am to 3pm.   Now you can run the 10 boxes during those times and use less boxes during non peak times…  Pretty cool.  And cheap!
