Parameter Explanation

  • Tags

    Tags are used to identify cloud resources. When you have multiple cloud resources of the same type, you can use tags to classify them based on usage, owner, or environment.

    If your organization has configured tag policies for DMS for Kafka, add tags to Kafka instances based on the policies. If a tag does not comply with the policies, Kafka instance creation may fail. Contact your organization administrator to learn more about tag policies.

    The tag naming rules are as follows:
