From Opscode: Data Driven Application Deployment with Chef - Blog - Opscode.
I was wondering when they were getting around to this. As I mentioned in a previous post, we're going to use "segments" at work, and that would be data-driven. In our case, it would be Rackspace Cloud Servers, not EC2 and Rackspace Cloud Files, not S3, but the principles remain the same. The databags seems like a great place to drop the descriptions in there, though I am not sure if I want to have it requery the index every 30 minutes.
