Tag a distribution - Amazon CloudFront (original) (raw)

Tags are words or phrases that you can use to identify and organize your AWS resources. You can add multiple tags to each resource, and each tag includes a key and a value that you define. For example, the key might be "domain" and the value might be "example.com". You can search and filter your resources based on the tags you add.

You can use tags with CloudFront, such as the following examples:

• Enforce tag-based permissions on CloudFront distributions. For more information, seeABAC with CloudFront.
• Track billing information in different categories. When you apply tags to CloudFront distributions or other AWS resources (such as Amazon EC2 instances or Amazon S3 buckets) and activate the tags, AWS generates a cost allocation report as a comma-separated value (CSV file) with your usage and costs aggregated by your active tags.
  You can apply tags that represent business categories (such as cost centers, application names, or owners) to organize your costs across multiple services. For more information about using tags for cost allocation, see Using cost allocation tags in the_AWS Billing User Guide_.

Notes

• You can tag distributions, but you can't tag origin access identities or invalidations.
• Tag Editor and Resource groups aren't currently supported for CloudFront.
• For the current maximum number of tags that you can add to a distribution, seeGeneral quotas.
