Azure Cost Optimization: 5 Strategies That Reduced Our Client Costs by 30%

Over the past year managing Azure environments for multiple clients, I've implemented cost optimization strategies that consistently deliver 20-30% savings. Here are the five most effective approaches that you can implement today.

1. Automated Right-Sizing with PowerShell

The biggest cost savings come from right-sizing resources. I developed a PowerShell script that analyzes VM utilization over 30 days and provides recommendations.

# Get VM utilization data
$vms = Get-AzVM
foreach ($vm in $vms) {
    $metrics = Get-AzMetric -ResourceId $vm.Id -MetricName "Percentage CPU" -TimeGrain 01:00:00
    # Analyze and recommend sizing
}

2. Reserved Instances Strategy

For predictable workloads, Reserved Instances provide up to 72% savings. I analyze usage patterns to identify the optimal RI mix.

3. Azure Hybrid Benefit Implementation

Leveraging existing Windows Server licenses through Azure Hybrid Benefit can reduce costs by up to 40% for Windows VMs.

4. Automated Resource Scheduling

Development and testing environments don't need to run 24/7. Automated start/stop schedules can save 60-70% on non-production costs.

5. Storage Optimization

Moving infrequently accessed data to cooler storage tiers and implementing lifecycle policies provides ongoing savings with minimal impact.
