GCP Cost Optimizer
Quick Start
Analyze GCP costs and implement optimization strategies to reduce spending.
Instructions
Step 1: Analyze current costs
# View billing data
gcloud billing accounts list
# Export billing data to BigQuery
gcloud billing accounts projects link PROJECT_ID \
--billing-account=BILLING_ACCOUNT_ID
# Query costs
bq query --use_legacy_sql=false \
'SELECT service.description, SUM(cost) as total_cost
FROM `project.dataset.gcp_billing_export`
WHERE DATE(_PARTITIONTIME) >= DATE_SUB(CURRENT_DATE(), INTERVAL 30 DAY)
GROUP BY service.description
ORDER BY total_cost DESC'Step 2: Identify optimization opportunities
Committed Use Discounts:
- 1-year or 3-year commitments
- Up to 57% savings for Compute Engine
- Up to 70% savings for Cloud SQL
Sustained Use Discounts:
- Automatic discounts for running instances
- Up to 30% for instances running >25% of month
Preemptible VMs:
- Up to 80% savings
- Suitable for fault-tolerant workloads
Rightsizing:
- Use Recommender API for suggestions
- Downsize overprovisioned instances
- Adjust machine types
Step 3: Implement cost-saving measures
# Get rightsizing recommendations
gcloud recommender recommendations list \
--project=PROJECT_ID \
--location=us-central1 \
--recommender=google.compute.instance.MachineTypeRecommender
# Apply recommendation
gcloud recommender recommendations mark-claimed \
RECOMMENDATION_ID \
--project=PROJECT_ID \
--location=us-central1 \
--recommender=google.compute.instance.MachineTypeRecommenderBest Practices
- Enable billing export to BigQuery
- Set up budget alerts
- Use labels for cost allocation
- Review Recommender suggestions monthly
- Implement committed use discounts for stable workloads
- Use preemptible VMs for batch processing
- Clean up unused resources regularly
- Optimize storage classes
