Resource Tags
Name-value labels applied to resources to organize them and track cost by project, owner, or environment.
Resource tags are name-value pairs — such as Environment: Production or CostCenter: Finance — attached to Azure resources, resource groups, or subscriptions for logical organization and granular cost tracking. Unlike resource groups, which impose a structural hierarchy, tags are flexible metadata overlaid on top, and a single resource can carry up to 50 tags. The key exam distinction is that tags are not inherited by default: a tag on a resource group does not automatically propagate to resources inside it. Azure Policy can require specific tags before deployment, while Cost Management + Billing uses tags to break down spending by project, team, or environment.
