Amazon Web Services (AWS) allows you to assign metadata to many of your AWS resources in the form of tags. Each tag is a simple label consisting of a key and an optional value to store information about the resource or data retained on that resource. This whitepaper focuses on tagging use cases, strategies, techniques, and tools that can help you to categorize resources by purpose, team, environment, or other criteria relevant to your business. Implementing a consistent tagging strategy can make it easier to filter and search for resources, monitor cost and usage, and manage your AWS environment.
