  - id: egress
    name: Egress / Data Transfer Out
    description: Data transfer out of R2 to the internet via the S3-compatible API, Cloudflare Workers, or public bucket domains — zero cost
    unit: GB
    unitPrice: 0.00
    freeTier: unlimited
    freeTierUnit: GB
    billingModel: always-free
    notes: This is R2's primary cost advantage over AWS S3 and GCS. Egress is always free regardless of volume.

optimization_strategies:
  - name: Use Infrequent Access for Cold Data
    description: Move objects not accessed regularly (logs, backups, archives) to the Infrequent Access storage class to reduce per-GB storage cost from $0.015 to $0.010. Ensure objects will remain for at least 30 days to avoid early deletion charges.
    savingsEstimate: 33%
    category: storage-tiering

  - name: Leverage the Free Tier
    description: Design workloads to stay within monthly free tier limits — 10 GB storage, 1 million Class A ops, 10 million Class B ops — for zero-cost operation. Multiple accounts can be used for isolation if needed.
    savingsEstimate: 100%
    category: free-tier-optimization

  - name: Use Workers Bindings for Internal Access
    description: Access R2 from Cloudflare Workers using native bindings instead of the S3 API to reduce operation overhead and latency without incurring additional API costs.
    savingsEstimate: variable
    category: architecture

  - name: Minimize Class A Operations
    description: Class A (write) operations cost 12.5x more than Class B (read) on standard storage ($4.50 vs $0.36 per million). Batch writes, use multipart uploads efficiently, and avoid unnecessary overwrites.
    savingsEstimate: variable
    category: operation-optimization

  - name: Eliminate Egress Costs via R2
    description: Migrating from AWS S3 or Google Cloud Storage to Cloudflare R2 eliminates egress fees entirely. AWS charges ~$0.09/GB and GCS ~$0.12/GB for egress. For workloads with high data transfer, this is the dominant cost saving.
    savingsEstimate: variable
    category: migration

  - name: Use Lifecycle Policies for Automatic Tiering
    description: Configure R2 object lifecycle policies to automatically transition objects to Infrequent Access storage or expire objects after a defined period, reducing manual management overhead and storage costs.
    savingsEstimate: variable
    category: automation

  - name: Custom Domains for High-Traffic Public Buckets
    description: For public buckets serving high traffic, use custom domains rather than r2.dev endpoints. Custom domains benefit from Cloudflare CDN caching, reducing the number of Class B operations billed by serving cached responses.
    savingsEstimate: variable
    category: caching

cost_allocation:
  - name: Bucket-Level Tagging
    description: Use distinct bucket names per team, project, or environment to enable cost allocation reporting via Cloudflare dashboard usage breakdowns.
    type: bucket-naming-convention

  - name: Multi-Account Isolation
    description: Use separate Cloudflare accounts for different business units or environments to get independent billing and free tier allowances per account.
    type: account-isolation

  - name: Cloudflare Analytics
    description: Monitor bucket-level usage via Cloudflare dashboard analytics to track storage, operations, and retrieval patterns for chargeback or showback.

forecasting:
  - name: Storage Forecast
    description: Estimate monthly storage cost as (peak_daily_GB_average * $0.015) - free_tier_10GB. Use Cloudflare dashboard metrics to track growth trends.
    formula: MAX(0, avg_daily_storage_GB - 10) * 0.015

  - name: Operations Forecast
    description: Separate Class A and Class B operation counts. Apply free tier deductions then multiply by per-million rates.
    formula:
      classA: MAX(0, monthly_class_a_ops - 1000000) / 1000000 * 4.50
      classB: MAX(0, monthly_class_b_ops - 10000000) / 1000000 * 0.36

  - name: Total Monthly Estimate
    description: Sum of storage + Class A ops + Class B ops + data retrieval (IA only). Egress is always zero.
    formula: storage_cost + class_a_cost + class_b_cost + data_retrieval_cost
