What it is: Tags used to categorize and track AWS costs by project/team/environment.

What it’s for:

• Attribute costs to owners (team A vs team B).
• Chargeback/showback and cost accountability.

Key ideas:

• You tag resources (e.g., Project=Quizz, Env=Prod).
• Cost reports and Cost Explorer can group by tags.

Exam cues:

• “track costs per department” → cost allocation tags.

Hard words:

• *attribute* /əˈtrɪbjuːt/: quy cho/gán cho
• *accountability* /əˌkaʊntəˈbɪləti/: trách nhiệm
• *department* /dɪˈpɑːrtmənt/: phòng ban
