Ariel, Since you are looking at server sizing in a cloud (Amazon's EC2) you may want to consider other offerings in your analysis. EC2 carves out memory and cpu as a limit, while other cloud offerings (built on Zen, i.e RackSpace) carves out memory and cpu as "committed" or garanteed minimum and thus your cloud instance can swell to use the available resources on the machine as they are available. Also, you want to look into failure scenarios, the Zen offereings are better at managing memory and disk in the recovery failde instances...
