How to organize resources and resource groups using 'Tags' in Azure Portal?

Do you know that you can logically organize your Azure resources by category? Once you login to Microsoft Azure portal, you can categorize them by using Tags. Tags enable you to retrieve related resources from different Resource Groups.

To know how to organize Azure resources using tags, let's discuss this in today's post as part of my Azure Tips and Tricks series.

Tags are defined by using name/value pairs, which you can attach to any resource or resource group. Each resource or resource group can have a maximum of 15 tags associated with it and each tag can have a character limit on their name and value. There are some other limitations too, which we will be discussing at the end of the post.
