Leadership can't tell which team owns which cloud spend. What's the foundational step toward per-team cost allocation and accountability?
A.Move everything into one account
Consolidating accounts reduces isolation — the opposite direction.
B.Enforce a tagging strategy (e.g., cost-center/team) and activate cost allocation tags — surfaced in Cost Explorer and CUR
Correct. Tags + activation = the standard allocation mechanism.
C.Ask teams to self-report monthly
Self-reporting is unreliable and manual.
D.Split billing into separate invoices manually
AWS consolidated billing doesn't produce per-team invoices automatically.
Why this answer
Cost allocation tags make spend attributable: enforced via tag policies in Organizations, then activated in Billing so Cost Explorer/CUR can group by them. Account structure helps too, but tags are the flexible cross-account attribution layer.
