We're currently using CloudFormation to deploy our web environment in AWS. The CloudFormation-script we use is based on this template created by Amazon: http://vstoolkit.amazonwebservices.com/CloudFormationTemplates/LoadBalanced.template. We have done some modifications to it but the basic structure is the same (you will of course get access to the actual script if you get the job).
What this script does is that it basically creates a CF-stack with an ELB, the underlying EC2-instances and AutoScaling-groups.
