Instance tagging is a great way to manage and monitor instances. It is also the way to do departmental billing and now with EC2 IAM resource level permissions a method to control the actions users and groups can perform on EC2 instances (more here: http://aws.amazon.com/about-aws/whats-new/2013/07/08/announcing-resource-permissions-for-amazon-ec2-and-amazon-rds/)
Placing tags on EC2 instances is this easy:
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=Cost Center,Value=AWS"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=tier,Value=database"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=environment,Value=test"
aws ec2 create-tags --resources i-f0ef69c6 --tags "Key=email,Value=thomas.laszewski@gmail.com"
Most monitoring and billing tools (CloudHealth, Cloudcheckr etc) use tagging to manage, monitor, and report costs and usage.

To view all instances (and the value) with the cost center tag issue the following command:
aws ec2 describe-tags --filters "Name=key,Values=Cost Center"Most monitoring and billing tools (CloudHealth, Cloudcheckr etc) use tagging to manage, monitor, and report costs and usage.
