In Azure, tags are key-value pairs that help you categorise and organise your resources, resource groups, and subscriptions. Think of tags like labels or logical folders that enable you to:
- Logically group related resources together
- Classify resources by purpose, environment, department, or cost center
- Filter and search for resources based on tags
- Apply policies and governance rules to tagged resources
- Track costs and budgets by tagged resources
You apply tags to your Azure resources, resource groups, and subscriptions to logically organise them into a taxonomy.
A taxonomy is a structured hierarchy of tags, allowing you to create a logical organization system. For example:
- Environment (Production, Development, Testing)
- Department (IT, Finance, Marketing)
- Resource Type (VM, Storage, Database)
By applying tags to your Azure resources, you can:
- Simplify resource management
- Improve resource discovery
- Enhance security and compliance
- Optimize cost tracking and budgeting
- Streamline policy enforcement
