Scale a web app manually

In this scenario you will learn to create a resource group, app service plan and web app. You will then scale the App Service Plan from a single instance to multiple instances.

If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Login-AzureRmAccount to create a connection with Azure.

Sample script


# Generates a Random Value
$Random=(New-Guid).ToString().Substring(0,8)

# Variables
$ResourceGroupName="myResourceGroup$random"
$AppName="AppServiceManualScale$random"
$Location="WestUS"

# Create a Resource Group
New-AzureRMResourceGroup -Name $ResourceGroupName -Location $Location

# Create an App Service Plan
New-AzureRMAppservicePlan -Name AppServiceManualScalePlan -ResourceGroupName $ResourceGroupName -Location $Location -Tier Basic

# Create a Web App in the App Service Plan
New-AzureRMWebApp -Name $AppName -ResourceGroupName $ResourceGroup -Location $Location -AppServicePlan AppServiceManualScalePlan

# Scale Web App to 2 Workers
Set-AzureRMAppServicePlan -NumberofWorkers 2 -Name AppServiceManualScalePlan -ResourceGroupName $ResourceGroupName

Clean up deployment

After the script sample has been run, the following command can be used to remove the resource group, web app, and all related resources.

Remove-AzureRmResourceGroup -Name myResourceGroup -Force
