Integrating Django with a Content Delivery Network (CDN) can greatly enhance your application’s performance by distributing the static content to multiple servers located in various regions worldwide, making your site faster and more reliable. Django is a high-level Python Web framework that supports the use of CDN for the efficient delivery of content.
Firstly, it’s essential to understand that Django static files such as CSS, JavaScript, and images aren’t served by Django in a production environment but instead using a web server or a CDN. This practice makes your Django app significantly more performant because those servers can send static files more efficiently than a Django app.
To integrate Django with a CDN, a popular choice among developers is Amazon CloudFront, which integrates smoothly with Django.
To make this integration, follow the steps below:
1. Set Up Amazon CloudFront: Create a new distribution, ensuring that you enable HTTP/2, IPv6, and Compress Objects Automatically settings for boosted performance. In the “Origin Domain Name,” leaving it blank would default it to your S3 bucket.
1. Update Django Settings: In your settings.py file, update STATIC_URL and STATICFILES_STORAGE. For the STATIC_URL, set it to your CloudFront URL. STATICFILES_STORAGE should be set as ‘storages.backends.s3boto3.S3Boto3Storage’.
1. Collect Your Static Files: Django has a built-in `collectstatic` management command to help you gather static files into `STATIC_ROOT`. Run `python manage.py collectstatic` in your console. The command will copy all files from your static folders into the STATIC\_ROOT directory.
1. Test Your Setup: After the completion of the above steps, the CloudFront CDN is now serving your Django static files. Verify that your Django app is appropriately serving static files using the CDN by loading your website and reviewing the source of a static file.
Please note, these steps are for Amazon CloudFront, which is just one of the many CDN options. Depending on the CDN choice, the integration steps might be different.
On a side note, integrating a CDN with Django and caching the static files can significantly improve the user experience by reducing page load times, improving website speed, and reducing bandwidth costs.

Remember, this is a basic overview and there’s a lot you can do when integrating Django with CDN, like customizing caching policies and invalidating updated files. Thus, having a good understanding of the chosen CDN and Django’s static files handling is essential to know how to make the best use of Django and CDN integration and improving your application’s performance.
