To create autoscaling webfarms I use Scalr too. As Tim reported is a powerful cloud orchestration tool, available as an online service or as an opensource software (PHP/Python/JS) that you can install on your servers. I must confirm that there is no more free trial for the service and the pricing is based on the number of hosts you manage. > Does that sound about right?

Then I suppose you have to update your ELB configuration and probably something else ... All these tasks can be configured with a tool like Scalr through a web interface and this simplifies your life, but it's something to pay for, while cloudformation is a free feature on AWS, for what I remember.
