afdfailover.ps1

<#
The scenario below we have four URIs:
1) afduri - pointing to the frontdoor name which has WebApps backends hosted in three different Azure Regions (EastUS, WestUS and CentralUS)
2) easturi - East US WebApp
3) westuri - West US WebApp
4) centraluri - Central US WebApp

1st GOAL - When client sends a request to Azure Front Door URI it will show
2nd GOAL - Turn off primary WebApp and validate failover from one region to another.

$afduri="https://webapp.danmauser.com"
$easturi="http://eastusdm.azurewebsites.net"
$westuri="http://westusdm.azurewebsites.net"
$centraluri="http://centraldm.azurewebsites.net"


# Requests to Front Door
While ($true) {
    (Invoke-WebRequest -Uri $afduri -DisableKeepAlive).content
    Start-Sleep -Seconds 1
  }

#Stop CentralUS WebApp to simulate Failover
Stop-AzWebApp -ResourceGroupName WebApps -Name centraldm

#Stop EastUS WebApp to simulate Failover
Stop-AzWebApp -ResourceGroupName WebApps -Name eastusdm


#Restart Web Apps
Start-AzWebApp  -ResourceGroupName WebApps -Name centraldm
Start-AzWebApp  -ResourceGroupName WebApps -Name eastusdm

### Example on how to test performance on Azure Front Door
### This is shell script and has to be executed over Bash
### Make sure your AFD Route Rule has cache enabled 
### Replace url1 with the Backend URI
### Replace url2 with the Frondoor URI
