"It's basically VPS but where you pay by the hour and it doesn't have a static IP and persistent hdd. You can also use a AMI with what do you need (I saw there was one for Rails)." Yeah I'm looking to setup something where I can point a domain to a load balancer instance (but if it needs to be restarted and changes instance URL, the domain no longer points to the right one?) so I can essentially run an entire site/app off of EC2. But then again it's probably better off to make a regular server be the load balancer I'm guessing. Since EC2 doesn't have persistent hdd - where do ppl keep databases? Not on S3 the latency would be up there.. in RAM on EC2? I pre-ordered the O'Reilly EC2/S3 book months ago.. it should be shipping in March I think.
