Again about how to save money on Azure. Developers used their applications for testing on a higher plan, and after the tests were finished, they manually switched the App Service Plan to a smaller size “Instance Size = Small” and the free layer “Pricing Tier = Free”. That’s cool, but sometimes they forgot about it. It consumed money needlessly until they remembered it.
So a script was created that was run every day, automatically after finishing work. He checked if the apps were on the right plan, if they weren’t switched. It is important to note that the App Service Plan can be changed to a lower plan only if you turn off the “alwaysOn” option, which starts automatically with a higher plan.
$ResourceGroupName = "Resource_group_Name"
$AppServicePlan = "AppServicePlan_Name"
$Tier = "Free"
$Size = "Small"
$PropertiesObject = @{alwaysOn = $false;}
$asp=Get-AzureRmAppServicePlan -ResourceGroupName $ResourceGroupName -Name $AppServicePlan
$apps=Get-AzureRmWebApp -AppServicePlan $asp
Foreach($app in $apps)
{
$websiteName = $app.Name
Set-AzureRmResource -PropertyObject $PropertiesObject -ResourceGroupName $app.ResourceGroup -ResourceType Microsoft.Web/sites/config -ResourceName $websiteName/web -Force
}
Set-AzureRmAppServicePlan -ResourceGroupName $ResourceGroupName -Name $AppServicePlan -Tier "$Tier" -WorkerSize "$Size"The script can be run in any way, I prefer via 'Automation Account'.
If you don’t know how to create an ‘automation account’, see this article, everything is explained step by step.
