Tags improve reporting for cloud resources Cloud admins can enrich tracking and billing data for cloud resources by configuring the system to auto-tag resources when they are provisioned. For example, when resources are tagged with a Cost Center tag, the reports can present the billing data segregated by cost center. Tagging resources creates metadata in the system billing line item records that allows cloud administrators to categorize costs into bins. The tag metadata is a key/value pair, for example, Cost Center=Retail. Because a cloud resource can have multiple tags, you can view cost items from multiple perspectives. The system tags resources during provisioning either automatically using provisioning rules or manually when the requester provides tag values while requesting the resource. After a resource is provisioned, you can view the tag settings but cannot alter the tag values. Amazon supports bulk-tagging of resources. You typically use bulk-tagging to apply tags to resources that were created outside ServiceNow Cloud Management. Azure does not support bulk-tagging. Azure: The system generates a unique Tag Set ID number and applies the ID to a resource when the resource is provisioned. Along with the other tags for the resource, the system pushes the ID to the cloud provider as the value for the Tag Set tag. Tag key/value mappings are stored in the instance as references as soon as the CI is created (pre-provision). When pushed to the provider, they will use the display names of the referenced values. Tagging allows you to track resources in several dimensions: Ownership Cost management Business service/application relationships Audit and compliance Monitor account/subscription proliferation ServiceNow Cloud Management provides the following default tags: Application Cost Center Project Service User Name A tag can have any of the following value types: Constant value Reference to a field of an sc_req_item Service catalog variable Script CloudFormation administrators can categorize and assign metadata to Amazon Web Services (AWS) resources by tagging them.

View the tags for a cloud resourceAfter the resource is provisioned, you can view the tag settings but you cannot edit the tag values.Auto-assign tags to outside resources for AWS bulk taggingBulk tagging for AWS enables you to update the standard tag values for resources that were created outside of the ServiceNow instance. This process ensures consistent meaningful reporting.Verifying that mandatory tags are appliedBefore a VM instance is provisioned to a user, a workflow verifies that mandatory tags are applied to the instance.Discover which resources are missing tagsYou can discover and report on AWS resources that are not tagged.Extension points for auto-taggingAmazon CloudFormation uses extension points in the vm_extension_point table.
