Scale a web app worldwide with a high-availability architecture

In this scenario you will create a resource group, two app service plans, two web apps, a traffic manager profile, and two traffic manager endpoints. Once the exercise is complete you will have a high-available architecture which allows provides global availability of your web app based on the lowest network latency.

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

# Variables

# Create a Resource Group
New-AzureRMResourceGroup -Name $ResourceGroupName -Location $Location1

# Create Traffic Manager Profile
New-AzureRMTrafficManagerProfile -Name "$ResourceGroupName-tmp" -ResourceGroupName $ResourceGroupName -TrafficRoutingMethod Performance -MonitorPath '/' -MonitorProtocol "HTTP" -RelativeDnsName $ResourceGroupName -Ttl 30 -MonitorPort 80

# Create an App Service Plan
New-AzureRMAppservicePlan -Name "$App1Name-Plan" -ResourceGroupName $ResourceGroupName -Location $Location1 -Tier Standard
New-AzureRMAppservicePlan -Name "$App2Name-Plan" -ResourceGroupName $ResourceGroupName -Location $Location2 -Tier Standard

# Create a Web App in the App Service Plan
$App1ResourceId=(New-AzureRMWebApp -Name $App1Name -ResourceGroupName $ResourceGroupName -Location $Location1 -AppServicePlan "$App1Name-Plan").Id
$App2ResourceId=(New-AzureRMWebApp -Name $App2Name -ResourceGroupName $ResourceGroupName -Location $Location2 -AppServicePlan "$App2Name-Plan").Id

# Create Traffic Manager Endpoints for Web Apps
New-AzureRMTrafficManagerEndpoint -Name "$App1Name-$Location1" -ResourceGroupName $ResourceGroupName -ProfileName "$ResourceGroupName-tmp" -Type AzureEndpoints -TargetResourceId $App1ResourceId -EndpointStatus "Enabled"
New-AzureRMTrafficManagerEndpoint -Name "$App2Name-$Location2" -ResourceGroupName $ResourceGroupName -ProfileName "$ResourceGroupName-tmp" -Type AzureEndpoints -TargetResourceId $App2ResourceId -EndpointStatus "Enabled"

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

Script explanation

This script uses the following commands. Each command in the table links to command specific documentation.

Command Notes
New-AzureRmResourceGroup Creates a resource group in which all resources are stored.
New-AzureRMTrafficManagerProfile Creates a Traffic Manager profile.
New-AzureRmAppServicePlan Creates an App Service plan.
New-AzureRmWebApp Creates a web app.
New-AzureRMTrafficManagerEndpoint Creates an endpoint in a Traffic Manager profile.
