Covers compute, storage, network, and operational cost patterns. ## Core principles 1. Measure before cutting — rightsizing requires utilization data, not guesses 2. Tag everything — cannot optimize what cannot be attributed 3. Right-size before committing — buying reservations for wrong size locks in waste 4. Dev/staging should sleep — idle non-production is the largest hidden cost 5. Egress costs are silent killers — always put CDN in front of public content ## References available - `references/aws-cost-patterns.md` — Reserved instances, spot (up to 90% savings), Savings Plans, right-sizing, S3 tiers - `references/gcp-cost-patterns.md` — Committed use, preemptible VMs, BigQuery slot pricing, egress optimization - `references/general-optimization.md` — Caching to reduce compute, CDN for egress, autoscaling tuning, unused resource detection - `references/cost-monitoring.md` — Budget alerts, anomaly detection, dev auto-stop, showback/chargeback, FinOps maturity--- name: cost-optimization-a7a3ba5423f7 description: | Cloud cost optimization patterns.
