Tags

Impacted by Governance

A Tagging Policy might prevent you from adding custom tags. 

Scalr automatically tags EC2 instances and EBS volumes provisioned through the Database Settings Tab and the Storage Tab. If there is no Governance policy restricting tags, you may add additional tags here.

Tag values support Global Variable Interpolation. The Global Variables in scope are that of the instance being tagged (for instances), or that of the instance provisioning the volume (for EBS volumes).
