Tags in Azure provide admins with a way of organizing Azure resources logically, using user-defined properties. Tags can be applied to entire resource groups or to resources directly. Using tags allows you to select resources or resource groups from the console, web portal, PowerShell, and even through the API. Tags are commonly used to organize resources for billing and management.

Each tag consists of a name and a value. For example, many admins will tag their production resources in Azure with an Environment tag and a value of Production. Doing so allows you to identify easily and group production resources.

By using tags, you can retrieve all related resources in an Azure subscription, based on the values of the tags. Tags can be placed on Compute, Network, and Storage resources during creation, as well as after resource creation, using PowerShell. This section will concentrate on how to view and edit tags placed on virtual machines.
