AKS vs App Service vs Functions decision in Azure - Hands-On Comparison

AKS vs App Service vs Functions Decision Guide

📖 Scenario: You are working as a cloud architect for a company that wants to deploy a new web application. The company is unsure whether to use Azure Kubernetes Service (AKS), Azure App Service, or Azure Functions. Your task is to help them understand the differences and decide which service fits their needs best.

🎯 Goal: Build a simple decision helper in Python that stores key characteristics of AKS, App Service, and Functions, then helps decide which service to use based on application needs.

📋 What You'll Learn

Create a dictionary with exact keys 'AKS', 'App Service', and 'Functions' and their descriptions

Add a configuration variable called app_type with the value 'web', 'api', or 'event-driven'

Write a function called choose_service that returns the best service based on app_type

Add a final line that calls choose_service with app_type and stores the result in selected_service

💡 Why This Matters

🌍 Real World

Helps beginners understand when to use AKS, App Service, or Functions in Azure for different app needs.

💼 Career

Cloud architects and developers often decide which Azure compute service to use based on app requirements.

1

Create service descriptions dictionary

Create a dictionary called services with these exact entries: 'AKS' with value 'Container orchestration for complex apps', 'App Service' with value 'Managed platform for web apps', and 'Functions' with value 'Serverless event-driven compute'.

Azure

# Create the services dictionary with exact keys and values
# Your code here

Need a hint?

Use a dictionary with keys exactly as 'AKS', 'App Service', and 'Functions'. Assign the exact string values given.

2

Add application type configuration

Add a variable called app_type and set it to the string 'web'.

Azure

services = {
    'AKS': 'Container orchestration for complex apps',
    'App Service': 'Managed platform for web apps',
    'Functions': 'Serverless event-driven compute'
}
# Set the app_type variable to 'web'
# Your code here

Need a hint?

Just assign the string 'web' to the variable named app_type.

3

Write service selection function

Write a function called choose_service that takes app_type as input and returns 'App Service' if app_type is 'web', 'Functions' if app_type is 'event-driven', and 'AKS' if app_type is 'api'.

Azure

services = {
    'AKS': 'Container orchestration for complex apps',
    'App Service': 'Managed platform for web apps',
    'Functions': 'Serverless event-driven compute'
}
app_type = 'web'
# Define choose_service function below
# Your code here

Need a hint?

Use if-elif statements to check app_type and return the correct service string.

4

Call function and store result

Add a line that calls choose_service with app_type and stores the result in a variable called selected_service.

Azure

services = {
    'AKS': 'Container orchestration for complex apps',
    'App Service': 'Managed platform for web apps',
    'Functions': 'Serverless event-driven compute'
}
app_type = 'web'

def choose_service(app_type):
    if app_type == 'web':
        return 'App Service'
    elif app_type == 'event-driven':
        return 'Functions'
    elif app_type == 'api':
        return 'AKS'

# Call choose_service with app_type and store in selected_service
# Your code here

Need a hint?

Call the function with the variable app_type and assign the result to selected_service.
