Scale an App Service app worldwide with a high-availability architecture using Azure CLI

This sample script creates a resource group, two App Service plans, two apps, a traffic manager profile, and two traffic manager endpoints. Once the exercise is complete, you have a high-available architecture, which provides global availability of your app based on the lowest network latency.

If you don't have an Azure subscription, create a free account before you begin.

Open Azure Cloud Shell

Azure Cloud Shell is a free, interactive shell that you can use to run the steps in this article. Common Azure tools are preinstalled and configured in Cloud Shell for you to use with your account. Select Copy to copy the code, paste it in Cloud Shell, and then press Enter to run it. There are a few ways to open Cloud Shell:

Select Try It in the upper-right corner of a code block. Example of Try It for Azure Cloud Shell
Open Cloud Shell in your browser. Launch Azure Cloud Shell button
Select the Cloud Shell button on the menu in the upper-right corner of the Azure portal. Cloud Shell button in the Azure portal

If you choose to install and use the CLI locally, you need Azure CLI version 2.0 or later. To find the version, run az --version. If you need to install or upgrade, see Install the Azure CLI.

Sample script

#/bin/bash

# Variables
trafficManagerDnsName="myDnsName$random"
app1Name="AppServiceTM1$random"
app2Name="AppServiceTM2$random"
location1="WestUS"
location2="EastUS"

# Create a Resource Group
az group create --name myResourceGroup --location $location1

# Create a Traffic Manager Profile
az network traffic-manager profile create --name $trafficManagerDnsName-tmp --resource-group myResourceGroup --routing-method Performance --unique-dns-name $trafficManagerDnsName

# Create App Service Plans in two Regions
az appservice plan create --name $app1Name-Plan --resource-group myResourceGroup --location $location1 --sku S1
az appservice plan create --name $app2Name-Plan --resource-group myResourceGroup --location $location2 --sku S1

# Add a Web App to each App Service Plan
site1=$(az webapp create --name $app1Name --plan $app1Name-Plan --resource-group myResourceGroup --query id --output tsv)
site2=$(az webapp create --name $app2Name --plan $app2Name-Plan --resource-group myResourceGroup --query id --output tsv)

# Assign each Web App as an Endpoint for high-availabilty
az network traffic-manager endpoint create -n $app1Name-$location1 --profile-name $trafficManagerDnsName-tmp -g myResourceGroup --type azureEndpoints --target-resource-id $site1
az network traffic-manager endpoint create -n $app2Name-$location2 --profile-name $trafficManagerDnsName-tmp -g myResourceGroup --type azureEndpoints --target-resource-id $site2

Clean up deployment

After the sample script has been run, the following command can be used to remove the resource group and all resources associated with it.

az group delete --name myResourceGroup

Script explanation

This script uses the following commands to create a resource group, App Service app, traffic manager profile, and all related resources. Each command in the table links to command specific documentation.

Command Notes
az group create Creates a resource group in which all resources are stored.
az appservice plan create Creates an App Service plan.
az webapp create Creates an App Service app.
az network traffic-manager profile create Creates an Azure Traffic Manager profile.
az network traffic-manager endpoint create Adds an endpoint to an Azure Traffic Manager Profile.
