Cloud Cost Governance ``` FINOPS MATURITY MODEL ═══════════════════════════════════════ Phase 1: INFORM (Visibility) ═══════════════════════════════════════ → Centralized cloud cost dashboard → Cost breakdown by: service, team, project, environment → Daily cost tracking → Tagging policy enforcement → Budget alerts (80%, 90%, 100%) Phase 2: OPTIMIZE (Efficiency) ═══════════════════════════════════════ → Right-sizing recommendations → Reserved instance / savings plan coverage → Idle resource identification → Storage tier optimization → Commitment-based pricing adoption Phase 3: OPTIMIZE (Architecture) ═══════════════════════════════════════ → Architecture cost review → Multi-region cost analysis → Spot instance adoption → Serverless evaluation → Data transfer optimization Phase 4: OPERATE (Culture) ═══════════════════════════════════════ → Showback/chargeback implementation → Cost ownership accountability → FinOps training for engineering → Cost/performance trade-off reviews → Quarterly business reviews CURRENT MATURITY: Phase 2 (Optimize - Efficiency) ``` ### 2.
