principles:
  - name: Visibility
    description: Use Volume Licensing Service Center exports for perpetual core/CAL counts; pull Azure
      Cost Management for Arc-billed pay-as-you-go core-hours; tag servers with workload owner via
      Azure Arc machine tags.
  - name: Allocation
    description: Allocate Datacenter packs to virtualization clusters and Standard packs to physical
      hosts; charge CALs back per business unit; Arc-billed PAYG can be tagged at the server level for
      direct chargeback.
  - name: Optimization
    description: Consolidate VM density to fewer Datacenter-licensed hosts; right-size cores (avoid
      over-licensing 8-core servers with 16-core packs); use Azure Hybrid Benefit for cloud workloads;
      switch bursty / dev workloads to PAYG instead of perpetual.
  - name: Accountability
    description: Assign a license owner per cluster; review CAL consumption against headcount quarterly;
      reconcile PAYG core-hours against forecast.
