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

What would be the cost equivalent of hosting it yourself outside of cloud computing?– MikeNJul 13, 2009 at 20:39
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.
- Calculate the cost of using traditional hosting
- Calculate the cost of using cloud hosting
- Find the difference between #1 and #2
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.
