Create Update and Delete Tags on Azure Resource

Learn more about how to use tags to organize your Azure resources and management hierarchy. Also learn the cmdlet used to fetch tags from Azure resources.

What is Tag in Azure Resources?

• You apply tags to your Azure resources, resource groups, and subscriptions to logically organize them into a taxonomy.
• Each tag consists of a name and a value pair. For example, you can create tag and apply the name “Environment” and the value “Stage” to all the resources in stage. Learn more about Tagging ideas
• Tag names are case-insensitive : Example: “Environment” or “environment” they are same tag names.
• Tag values are case-sensitive : Example: “Stage” or “stage” they are different tag values.
