Azure Cost Optimizer
Quick Start
Analyze Azure costs and implement optimization strategies to reduce spending while maintaining performance.
Instructions
Step 1: Analyze current costs
# View cost analysis
az cost-management query \
--type Usage \
--dataset-aggregation name="PreTaxCost" function="Sum" \
--dataset-grouping name="ResourceGroup" type="Dimension"
# View costs by service
az cost-management query \
--type Usage \
--dataset-grouping name="ServiceName" type="Dimension"Step 2: Identify optimization opportunities
Check for unused resources:
- Unattached disks
- Idle virtual machines
- Unused public IPs
- Orphaned network interfaces
Review resource utilization:
- VM CPU and memory usage
- Database DTU utilization
- Storage account access patterns
- Network bandwidth usage
Step 3: Implement cost-saving measures
Reserved Instances:
- 1-year or 3-year commitments
- Up to 72% savings vs pay-as-you-go
- Recommended for stable workloads
Azure Hybrid Benefit:
- Use existing Windows Server licenses
- Use existing SQL Server licenses
- Significant cost savings
Rightsizing:
- Downsize overprovisioned VMs
- Adjust database tiers
- Optimize storage tiers
Spot VMs:
- Up to 90% savings
- Suitable for interruptible workloads
- Batch processing, dev/test
