Organize Azure resources using tags, which are name-value pairs.
- **Characteristics:**
- Tags can be added, modified, and deleted using various tools (PowerShell, Azure CLI, ARM templates, REST API, Azure portal).
- Tags applied to a resource group are not inherited by the resources within the group.
- **Design Considerations:**
- Align tags with organizational taxonomy for easier understanding.
- Use IT-aligned or business-aligned tagging strategies, or a combination of both.
- Categories of tags include functional, classification, accounting, partnership, and purpose.
- Start with a few tags and scale out based on effectiveness.
- Use [[Azure Policy]] to enforce tagging rules and conventions.
- Determine which resources require tagging, focusing on mission-critical ones.
| Tag type | Description | Example name-value pairs |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------- |
| **Functional** | Functional tags categorize resources according to their purpose within a workload. This tag shows the deployed environment for a resource, or other functionality and operational details. | - `app = catalogsearch1` <br>- `tier = web` <br>- `webserver = apache` <br>- `env = production, dev, staging` |
| **Classification** | Classification tags identify a resource by how it's used and what policies apply to it. | - `confidentiality = private` <br>- `SLA = 24hours` |
| **Accounting** | Accounting tags allow a resource to be associated with specific groups within an organization for billing purposes. | - `department = finance` <br>- `program = business-initiative` <br>- `region = northamerica` |
| **Partnership** | Partnership tags provide information about the people (other than IT members) who are associated with a resource, or otherwise affected by the resource. | - `owner = jsmith` <br>- `contactalias = catsearchowners` <br>- `stakeholders = user1;user2;user3` |
| **Purpose** | Purpose tags align resources to business functions to better support investment decisions. | - `businessprocess = support` <br>- `businessimpact = moderate` <br>- `revenueimpact = high` |
