Azure Cost Optimizer

Quick Start

Analyze Azure costs and implement optimization strategies to reduce spending while maintaining performance.

Instructions

Step 1: Analyze current costs

bash
# 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
