Introduction

This guided project focuses on building a simple HTTP endpoint using Azure Functions.

Azure Functions is a serverless compute service that lets you run code in response to events without managing infrastructure. You write a function, deploy it, and Azure handles the scaling and hosting. With an HTTP trigger, your function gets its own URL that anyone can call from a browser.

Scenario

Your team needs a lightweight endpoint for a contact page without maintaining servers. You create a Function App, deploy an HTTP-triggered function using Cloud Shell, and then test, secure, and monitor the endpoint—all in one session.

• Exercise 1 - Create a Function App with the serverless Flex Consumption plan.
• Exercise 2 - Deploy an HTTP-trigger function from Cloud Shell.
• Exercise 3 - Test the endpoint, add security, and review logs.

By the end of this project, you have a live HTTP endpoint that responds to requests, requires an access key for security, and logs every invocation to Application Insights.

Skilling areas

In this project, you practice skills in the following areas:

Create and configure a Function App

• Create a resource group and a Function App.
• Select the Flex Consumption hosting plan.
• Verify deployment status in the portal.

Deploy a function using Cloud Shell

• Open Cloud Shell and initialize a function project.
• Create an HTTP-triggered function.
• Deploy the function to Azure from the command line.

Test, secure, and monitor a function

• Call the HTTP endpoint from a browser.
• Enable Application Insights for monitoring.
• Change the authorization level to require a function key.
• Review invocation logs and execution details.
