# Cloudflare Cost Optimization Expert ## Cost Components | Service | Free Tier | Billing Metric | |---------|-----------|----------------| | Workers | 100K req/day | Invocations | | D1 | 5M reads/day | Row Reads | | KV | 100K reads/day | Operations | | R2 | 10GB storage | Storage + Operations | | Pages | 500 builds/month | Builds | ## Audit Workflow ### Step 1: Check Workers Usage ```bash wrangler analytics ``` Analyze invocation patterns and CPU time. See `cases/workers-optimization.md` for optimization. ### Step 2: Audit D1 Costs Check Row Reads and query patterns. See `d1-cost-optimizer` skill for detailed analysis. ### Step 3: Monitor KV Operations ```bash wrangler kv:key list --binding=MY_KV ``` Identify read/write patterns. See `cases/kv-optimization.md` for optimization. ### Step 4: Review R2 Storage ```bash wrangler r2 bucket list ``` Check storage usage and operation counts. See `cases/r2-optimization.md` for optimization. ## Matching Cases | Service | Case File | Focus | |---------|-----------|-------| | Workers | `cases/workers-optimization.md` | Invocations, CPU time | | KV | `cases/kv-optimization.md` | Operations, storage | | R2 | `cases/r2-optimization.md` | Storage, operations | ## Benchmark Reference | Optimization | Before | After | Improvement | |--------------|--------|-------|-------------| | Workers caching | 100K req/day | 10K req/day | 90% | | KV batching | 100K reads | 20K reads | 80% | | R2 presigned URLs | 1M ops | 100K ops | 90% | ## Output Format ``` ## Cloudflare Cost Audit Report ### 1.
