  FinOps Framework 1.0 FOCUS-aligned cost management guidance for Drone CI/CD
  platform deployments. Drone's pricing model spans free open-source self-hosted
  deployments, free enterprise editions for qualifying organizations, and paid
  enterprise licenses starting at $299/month. Total cost of ownership for
  self-hosted deployments includes infrastructure, compute, storage, and
  operational overhead in addition to any license fees.

  - name: Infrastructure Cost
    description: >-
      For self-hosted deployments, organizations bear the cost of compute,
      storage, and networking resources to run the Drone server and build runners.
      Cloud provider costs vary by build volume, runner type, and region.
    type: variable
    drivers:
      - Build concurrency (number of parallel build runners)
      - Build duration and frequency
      - Storage for build artifacts and logs
      - Network egress for container image pulls
      - Database hosting (SQLite embedded, PostgreSQL, or MySQL for enterprise)

  - name: Compute Cost (Runners)
    description: >-
      Drone runners execute builds in isolated Docker containers. Each concurrent
      build requires a dedicated runner instance. Autoscaling (enterprise feature)
      can optimize compute costs by spinning up runners on demand and terminating
      them when idle.
    type: variable
    optimization:
      - Use autoscaling to avoid idle runner costs
      - Select appropriately sized compute instances for typical build workloads
      - Use spot/preemptible instances for non-critical build pipelines
      - Cache Docker layers and dependencies to reduce build duration

  - name: Storage Cost
    description: >-
      Build logs, artifacts, and container images consumed storage resources.
      Enterprise edition supports S3-compatible object storage for cost-effective
      artifact retention.
    type: variable
    optimization:
      - Configure log retention policies to purge old build logs
      - Use S3-compatible storage (enterprise) for cost-effective artifact storage
      - Implement artifact lifecycle policies to expire old builds

tagging:
  recommendations:
    - Tag compute resources with project, team, and environment labels for cost attribution
    - Use Drone repository and organization names as cost allocation dimensions
    - Track build minutes per repository to identify high-cost pipelines for optimization
