Section 5: Automating Cost Optimization with PowerShell Scripts

PowerShell is a command-line tool thatcan be used to automate the monitoring and cost optimization of Azure resources. In this section, we will provide sample PowerShell scripts that can be used to automate the cost optimization of Azure services.

Script 1: Schedule VMs to Start and Stop

This script can be used to schedule virtual machines to start and stop at specific times to reduce costs. By shutting down VMs when they are not needed, you can save money on compute resources.

$resourceGroupName = "YourResourceGroupName"
$vmName = "YourVMName"
$startTime = "06:00"
$stopTime = "18:00"

# Get the VM object
$vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName

# Set the automatic start and stop properties
$vm | Set-AzVMStartupTask -Location $vm.Location -TaskId "auto-start" -TaskName "AutoStart" -TaskType "PowerShell" -TaskCommandLine "powershell.exe -ExecutionPolicy Unrestricted -File C:\Scripts\AutoStart.ps1" -StartTime $startTime
$vm | Set-AzVMShutdownTask -Location $vm.Location -TaskId "auto-stop" -TaskName "AutoStop" -TaskType "PowerShell" -TaskCommandLine "powershell.exe -ExecutionPolicy Unrestricted -File C:\Scripts\AutoStop.ps1" -StopTime $stopTime

# Update the VM
Update-AzVM -ResourceGroupName $resourceGroupName -VM $vm

Script 2: Resize VMs Based on Usage

This script can be used to resize virtual machines based on their usage. By resizing VMs to match their workload, you can save money on compute resources.

$resourceGroupName = "YourResourceGroupName"
$vmName = "YourVMName"

# Get the VM object
$vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName

# Get the CPU usage percentage
$cpuUsage = (Get-AzMetric -ResourceId $vm.Id -TimeGrain 00:01:00 -MetricName "Percentage CPU" -AggregationType Average -StartTime (Get-Date).AddMinutes(-10)).Data[0].Average

# Resize the VM based on CPU usage
if ($cpuUsage -lt 20) {
    $vm | Update-AzVM -ResourceGroupName $resourceGroupName -SetSize Standard_B1s
} elseif ($cpuUsage -lt 50) {
    $vm | Update-AzVM -ResourceGroupName $resourceGroupName -SetSize Standard_B2s
} elseif ($cpuUsage -lt 80) {
    $vm | Update-AzVM -ResourceGroupName $resourceGroupName -SetSize Standard_B4ms
} else {
    $vm | Update-AzVM -ResourceGroupName $resourceGroupName -SetSize Standard_B8ms
}

Script 3: Delete Unused Resources

This script can be used to delete unused resources to reduce costs. By removing resources that are no longer needed, you can save money on storage and compute resources.

$resourceGroupName = "YourResourceGroupName"
$ageInDays = 30

# Get the list of resources
Get-AzResource -ResourceGroupName $resourceGroupName |
  ForEach-Object {
    $resource = $_
    $creationDate = $resource.Properties.createdTime
    $ageInDaysAgo = (Get-Date).AddDays(-$ageInDays)
    if ($creationDate -lt $ageInDaysAgo) {
      try {
        Write-Host "Deleting $($resource.ResourceType) resource $($resource.Name) created on $creationDate"
        Remove-AzResource -ResourceId $resource.ResourceId -Force -WhatIf
      }
      catch {
        Write-Error $_.Exception.Message
      }
    }
  }

This script performs the deletion in a pipeline. It also uses Get-Date().AddDays(-$ageInDays) to calculate the date of resources that are older than $ageInDays. The WhatIf parameter in Remove-AzResource is used to test the script without actually deleting the resources. Error handling is added using a try-catch block.
