Tags can be managed using PowerShell, Azure Resource Manager templates, portal, and REST API's. In this section, PowerShell will be used to create and apply tags. PowerShell provides a cmdlet for retrieving and attaching tags to resource groups and resources.

• To retrieve tags associated with a resource using PowerShell, the Find-AzureRMResource cmdlet can be used:

(Find-AzureRmResource -TagName Dept -TagValue Finance).Name

• To retrieve tags associated with a resource group using PowerShell, the following command can be used:

(Find-AzureRmResourceGroup -Tag @{ Dept="Finance" }).Name

• To set tags to a resource group, the Set-AzureRmResourceGroup cmdlet can be used:

Set-AzureRmResourceGroup -Name examplegroup -Tag @{ Dept="IT"; Environment="Test" }  

• To set tags to a resource, the Set-AzureRmResource cmdlet can be used:
