Tag Manager

Overview

The Tag manager feature allows users to create and manage tags across subscriptions and resources in Azure in a centralized way. A tag consists of a key and a value pair, which can be used for categorization, cost tracking, compliance, and governance.

Beyond manual tag creation, Tag manager enables rule-based automation. Users can define rules with filters and operators so that tags are applied automatically to the matching resources across multiple subscriptions.

This reduces manual effort, ensures consistency, and enforces organizational policies effectively.

Key Capabilities

• Tag Creation – Create tags with a Key and Value (e.g., Environment=Production).

• Filters & Rules – Build rules using filters such as Subscription, Resource Group, Resource Type, Resource, Location, or Tags with operators like Equals, Not Equals, Contains, Starts With, Ends With.
  Rules can be combined with AND/OR.

• Multi-Subscription Support – Rules evaluate resources across all subscriptions, applying tags automatically.

• Run Now – Allows users to immediately apply tags from updated rules or key/value changes to resources, without waiting for the scheduled run.

• Cloning – Quickly duplicate an existing rule and create a new configuration by updating only the key and value.

   • Choose the required operators (e.g., Equals, Contains) and specify the rule value.

3. Assign Rule to Tag
