principles:
  - name: Visibility
    description: Use S3 Storage Lens (free metrics, advanced metrics paid), Cost Explorer with the S3 dimension,
      bucket-level CloudWatch metrics, and CUR / FOCUS export for object-level cost.
  - name: Allocation
    description: Tag buckets with Application, Team, Environment; use cost allocation tags so charges flow
      through FOCUS columns; use S3 Storage Lens groups for grouping prefixes.
  - name: Optimization
    description: Use S3 Intelligent-Tiering for unknown access patterns, lifecycle policies to transition
      cold data to Glacier classes, S3 Storage Lens recommendations to find inefficient prefixes, multi-part
      upload cleanup, and CloudFront in front of public buckets to reduce egress.
  - name: Accountability
    description: Set AWS Budgets per bucket tag, configure anomaly detection on data transfer, and review
      Storage Lens dashboards monthly with bucket owners.
