You don't even need that, and I don't know why he mentioned that as an issue...I was able to flexibly balance with virtual hosts with HAProxy on EC2 like with any other server. The issues I was considering with la nuebla: Data is a pain. S3 is great in theory but a pain to integrate. The same goes for EBS, which is really pricey for more than a little. If you can get a good connection on your own and admin a simple file server, serving data is very easy, stable, and cheap. Amazon's options are prone to serious failure if you do something wrong with them. I don't lose my hard drive's contents when I accidentally pull the plug, but that is the case with EC2.
