Why serverless matters in Azure - See It in Action

Why Serverless Matters

📖 Scenario: You are working for a small startup that wants to build a simple web service without managing servers. Your team decides to use Azure serverless technology to save time and money.

🎯 Goal: Build a basic Azure Function app configuration that shows how serverless computing works and why it matters for developers and businesses.

📋 What You'll Learn

Create an Azure Function app configuration dictionary with exact keys and values

Add a configuration variable for the function timeout setting

Write a function trigger configuration using the HTTP trigger

Complete the function app configuration with the correct runtime stack

💡 Why This Matters

🌍 Real World

Serverless computing lets developers focus on writing code without worrying about servers. Azure Functions automatically scale and only charge when code runs.

💼 Career

Understanding serverless basics is important for cloud developers, DevOps engineers, and architects who design scalable, cost-efficient cloud applications.

1

Create the Azure Function app configuration dictionary

Create a dictionary called function_app_config with these exact entries: 'name': 'MyServerlessApp', 'location': 'East US', 'resource_group': 'ServerlessRG', and 'plan': 'Consumption'.

Azure

# Your code here

Need a hint?

Think of this dictionary as the basic setup for your Azure Function app.

2

Add the function timeout configuration

Add a variable called function_timeout and set it to the string '00:05:00' representing 5 minutes timeout for the function execution.

Azure

function_app_config = {
    'name': 'MyServerlessApp',
    'location': 'East US',
    'resource_group': 'ServerlessRG',
    'plan': 'Consumption'
}
# Your code here

Need a hint?

This timeout means the function will stop if it runs longer than 5 minutes.

3

Configure the HTTP trigger for the function

Create a dictionary called http_trigger with these exact entries: 'type': 'httpTrigger', 'direction': 'in', and 'authLevel': 'function'.

Azure

function_app_config = {
    'name': 'MyServerlessApp',
    'location': 'East US',
    'resource_group': 'ServerlessRG',
    'plan': 'Consumption'
}
function_timeout = '00:05:00'
# Your code here

Need a hint?

This trigger lets your function respond to web requests.

4

Complete the function app configuration with runtime stack

Add the key 'runtime_stack' with the value 'python' to the function_app_config dictionary.

Azure

function_app_config = {
    'name': 'MyServerlessApp',
    'location': 'East US',
    'resource_group': 'ServerlessRG',
    'plan': 'Consumption'
}
function_timeout = '00:05:00'
http_trigger = {
    'type': 'httpTrigger',
    'direction': 'in',
    'authLevel': 'function'
}
# Your code here

Need a hint?

This tells Azure to use Python for your serverless function.
