How can I calculate the required bandwith and cost of hosting a site that would have around 3 million unique visitors per year? I wanted to come up with an estimate of how much cost could be saved by using a cloud computing service like Amazon EC3 vs. using a traditional colocated server.

Amazon has a cost calculator to help you estimate these things: http://calculator.s3.amazonaws.com/calc5.html | |||

Roll 3d6 for savings, and 1d20 as a saving throw against not actually saving anything. Or, to be a little less facetious, there's no guarantee that you'll save anything using EC2. It depends on your IO, availability, and traffic profiles. Be careful not to underestimate the hard-to-estimate bits in EC2's cost calculator -- do you know how many IOPS you do to persistent storage each month? I'll bet it's more than you think. | |||

It's very simple in theory, but you're going to have to do the work yourself, we can't do it for you, since it depends on so many variables. | |||
