CDN caching rules in Azure - Mini Project: Build & Apply

Azure CDN Caching Rules Setup

📖 Scenario: You are managing a website hosted on Azure. To improve performance, you want to set up caching rules on Azure CDN to control how content is cached and served to users.

🎯 Goal: Build an Azure CDN caching rules configuration that sets caching behavior for specific file types and paths.

📋 What You'll Learn

Create a dictionary called cdn_endpoints with one endpoint named mycdnendpoint and its origin URL

Add a variable called cache_duration_seconds set to 3600

Create a list called caching_rules with a rule that caches .jpg and .png files for the duration in cache_duration_seconds

Add a final configuration dictionary called cdn_config that includes the endpoint and caching rules

💡 Why This Matters

🌍 Real World

Setting caching rules on Azure CDN helps speed up website loading by storing static content closer to users, reducing server load and bandwidth.

💼 Career

Cloud engineers and DevOps professionals often configure CDN caching to optimize application performance and cost.

1

Create the CDN endpoint dictionary

Create a dictionary called cdn_endpoints with one key 'mycdnendpoint' and its value set to 'https://myorigin.azurewebsites.net'.

Azure

# Create the cdn_endpoints dictionary
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact key and value.

2

Add cache duration variable

Add a variable called cache_duration_seconds and set it to 3600.

Azure

cdn_endpoints = {'mycdnendpoint': 'https://myorigin.azurewebsites.net'}
# Define cache_duration_seconds variable
# Your code here

Need a hint?

Set the variable to the number of seconds for caching.

3

Create caching rules list

Create a list called caching_rules with one dictionary inside. The dictionary must have keys 'name' with value 'imageCaching', 'file_extensions' with value ['.jpg', '.png'], and 'cache_duration' set to the variable cache_duration_seconds.

Azure

cdn_endpoints = {'mycdnendpoint': 'https://myorigin.azurewebsites.net'}
cache_duration_seconds = 3600
# Create caching_rules list with one caching rule dictionary
# Your code here

Need a hint?

Use a list with one dictionary containing the specified keys and values.

4

Combine into final CDN configuration

Create a dictionary called cdn_config with keys 'endpoint' set to cdn_endpoints['mycdnendpoint'] and 'caching_rules' set to the caching_rules list.

Azure

cdn_endpoints = {'mycdnendpoint': 'https://myorigin.azurewebsites.net'}
cache_duration_seconds = 3600
caching_rules = [{'name': 'imageCaching', 'file_extensions': ['.jpg', '.png'], 'cache_duration': cache_duration_seconds}]
# Create cdn_config dictionary combining endpoint and caching_rules
# Your code here

Need a hint?

Use a dictionary with the specified keys and values referencing previous variables.
