Today, Amazon EC2 Auto Scaling announced the ability to describe Auto Scaling groups using tags. Tag-based filtering makes it easier for you to view and manage your Auto Scaling groups based on the tags that you are interested in. Each tag is a simple label consisting of a customer-defined key and an optional value.
For example, you may have multiple Auto Scaling groups where you tag them to indicate what environment they are a part of (e.g., using the key "environment" whose value might be "dev", "test" or "prod"). Previously, you could determine which groups had the "environment:prod" tag by calling the describe-tags API first, and then describing the Auto Scaling groups that were returned. Now you can directly call the describe-auto-scaling-groups API and filter for the "environment:prod" tag.
