Tagging Strategies and Cost Allocation

Learn how to use resource tags and cost allocation tags to organize AWS resources, track spending by team or project, and enforce governance.

What Are Tags?

A tag is a key-value label you attach to AWS resources, like Environment=prod or Team=payments.

Tags are the foundation of organizing and tracking spending across a large AWS account.

Why Tagging Matters for Cost

Without tags, a bill is one big number. With tags, you can answer questions like:

  • How much does the staging environment cost?
  • Which team spends the most?
  • What is the cost of project X?
