Tagging AWS Elemental MediaConnect Resources

A tag is a custom attribute label that you assign or that AWS assigns to an AWS resource. Each tag has two parts:

  • A tag key (for example, CostCenter, Environment, or Project). Tag keys are case sensitive.

  • An optional field known as a tag value (for example, 111122223333 or Production). Omitting the tag value is the same as using an empty string. Like tag keys, tag values are case sensitive.

Tags help you do the following:

  • Identify and organize your AWS resources. Many AWS services support tagging, so you can assign the same tag to resources from different services to indicate that the resources are related. For example, you could assign the same tag to an AWS Elemental MediaConnect flow that you assign to an AWS Elemental MediaLive channel output.

  • Track your AWS costs. You activate these tags on the AWS Billing and Cost Management dashboard. AWS uses the tags to categorize your costs and deliver a monthly cost allocation report to you. For more information, see Use Cost Allocation Tags in the AWS Billing and Cost Management User Guide.

For tips on using tags, see the AWS Tagging Strategies post on the AWS Answers blog.

Tag Naming and Usage Conventions

The following basic naming and usage conventions apply to using tags with AWS Elemental MediaConnect resources:

  • Each resource can have a maximum of 50 tags.

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • The maximum tag key length is 128 Unicode characters in UTF-8.

  • The maximum tag value length is 256 Unicode characters in UTF-8.

  • Allowed characters are letters, numbers, spaces representable in UTF-8, and the following characters: . : + = @ _ / - (hyphen). Amazon EC2 resources allow any characters.

  • Tag keys and values are case sensitive. As a best practice, decide on a strategy for capitalizing tags, and consistently implement that strategy across all resource types. For example, decide whether to use Costcenter, costcenter, or CostCenter, and use the same convention for all tags. Avoid using similar tags with inconsistent case treatment.

  • The aws: prefix is prohibited for tags; it's reserved for AWS use. You can't edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

Managing Tags

Tags are made up of the Key and Value properties on a resource. You can use the AWS Elemental MediaConnect console, the AWS CLI, or the AWS Elemental MediaConnect API to add, edit, or delete the values for these properties. For information about working with tags, see the following:
