Introduction

By now, you have configured the Function App in Azure and updated the TollBooth application code. Now it’s time to start assembling the pieces of the puzzle by publishing the TollBooth application code to Azure and configuring the other Azure PaaS services to trigger it.

Description

In this challenge, you will deploy the TollBooth function code to the first Function App (.NET based, with name containing App) in Azure. You will also configure Event Grid so that when a file is uploaded to the Blob Storage container, it triggers the ProcessImage function hosted in the Function App in Azure.

Event Schema: Event Grid Schema.
Topic Type : Storage Accounts.
Resource : The first storage account you created.
Event type : Blob Created only
Endpoint type : Select your ProcessImage Azure Function
Filters: none

HINT: There are multiple ways to configure an Event Grid Subscription to a System Topic. One of the easiest is to start from the Storage Account. Navigate to the Events pane, then to the “Event Subscriptions” tab. You can pick any name for the Subscription or the System Topic Name.
