Storing media files in a CDN is another alternative supported in Magento. There is no full integration with a specific CDN, and you are responsible for choosing and configuring a CDN on your own. After configuring the CDN, you must complete the configuration from the Admin. The changes can be made at either the global or website level.
When a CDN is selected as media storage, all paths to media on the web store pages are changed to paths to the CDN. The process of retrieving media files stored in a CDN works as follows:
- When a customer opens a page in the store, the browser addresses the CDN with the request to acquire some media files, such as images
- If the CDN does not yet have these images in its storage, it requests them from the server, and provides images to the customer’s browser
- If the CDN already has the required images in storage, it simply serves the requested images to the customer’s browser
