# Scale an App Service app worldwide with a high-availability architecture
#
# 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.
