Tagging Your Amazon Config Resources

A tag is a label that you assign to an Amazon resource. Each tag consists of a key and an optional value, both of which you define. Tags make it easier to manage, search for, and filter resources.

Tags enable you to categorize your Amazon resources in different ways, for example, by purpose, owner, or environment. This is useful when you have many resources of the same type—you can quickly identify a specific resource based on the tags you've assigned to it. You can assign one or more tags to your Amazon resources. Each tag has an associated value.

We recommend that you devise a set of tag keys that meets your needs for each resource type. Using a consistent set of tag keys makes it easier for you to manage your Amazon resources. You can search and filter the resources based on the tags you add.

Tags are interpreted strictly as a string of characters and are not automatically assigned to your resources. You can edit tag keys and values, and you can remove tags from a resource at any time. You can set the value of a tag to an empty string, but you can't set the value of a tag to null. If you add a tag that has the same key as an existing tag on that resource, the new value overwrites the old value. If you delete a resource, any tags for the resource are also deleted.

You can work with tags using the Amazon Command Line Interface (Amazon CLI) and the Amazon Config API reference.
