There's already 4 public images on ec2 mentioning Asterisk in their names so wouldn't it be easier to try out one of those rather than install all the bits and pieces on a base Linux image? An interesting paper on ec2 and Asterisk would be one that discusses what the call quality is like from both inside and outside the US. When I briefy ran up an instance at this time last year it actually seemed ok. >From a provider's point of view running Asterisk on the ec2 cloud does pose some interesting questions. As a quick and dirty estimate if you assume one of the standard small ec2 instances could cope with 100 simultaneous g711 calls (I don't know if that is the case just guessing) then you'll chew up approx. 2MB/s (you pay for bandwidth both ways). Assuming that you'd then have 1MB/s average to account for quite and busy call times then it would be 3.6GB/hour or 86.4GB/day. At the Amazon price of $0.10/GB that's $8.64/day or $260/month. The server instance will cost you $72/month so total cost for 100/calls per month is $332. A typical dedicated server for $300/month is roughly equivalent to an ec2 small instance and comes with 500GB of bandwidth/month which is only a fifth of what's required but you could probably get the extra 2TB/month thrown in for $32/month making the dedicated server and ec2 prices the same. There are serious pros and cons between these approaches. With the ec2 you don't get a permanent static IP, with a dedicated server you do. With ec2 you could scale up and down between 1 server and 4 servers at the drop of a hat to save costs and cope with peak and quite times, with dedicated servers you're stuff with 12 or 24 month contracts for the number of servers you'd need under maximum load. And then of course the major factor for both is what the call quality will be like.
