📖 What is Azure Tags?
Azure Tags are name-value pairs applied to resources to categorize them for billing, management, and organization. Tags enable administrators to track costs across different departments or projects, making it easier to filter and organize resources within the Azure portal.
"When you see questions about 'cost tracking' or 'organizing resources by department,' Azure Tags are almost always the correct answer."

🔑 What are the Key Concepts of Azure Tags?
- ▸ Name-Value Pairs: Tags consist of a name (key) and a value, such as 'Environment: Production', allowing for flexible, custom categorization of Azure resources.
- ▸ Cost Management: Tags are primary tools for cost allocation, enabling administrators to group and track expenditures by project, department, or cost center.
- ▸ Logical Organization: They provide a way to organize resources across different resource groups and subscriptions without needing to move the actual resources.
- ▸ Inheritance Behavior: By default, tags applied to a resource group are not inherited by the resources contained within that group, requiring separate application.
- ▸ Filtering and Search: Tags allow users to quickly filter large sets of resources in the Azure Portal to find specific assets based on custom metadata.
🎯 How does Azure Tags appear on the AZ-900 Exam?
You may be asked to identify the best method for a company to track the monthly spending of multiple departments sharing a single Azure subscription.
A scenario might describe a need to organize resources by environment, such as Production, Development, and Testing, to generate specific cost reports for stakeholders.
Expect questions where you must distinguish between Resource Groups, which are logical containers, and Tags, which are metadata used for categorization and billing.
❓ Frequently Asked Questions
Do resources automatically inherit tags from the Resource Group they belong to?
No, tags are not inherited by default. If you tag a resource group, the resources inside remain untagged unless you use Azure Policy to automate the inheritance process.
Is there a limit to how many tags can be applied to a single resource?
Yes, Azure allows up to 50 tags per resource. Both the tag name and the value have character limits, so it is best to keep them concise.
Can tags be used to control access to resources?
Tags themselves do not grant permissions, but you can use Azure Policy in conjunction with Role-Based Access Control (RBAC) to manage resources based on their tag values.
