By integrating your website with a Content Delivery Network (CDN), you can take advantage of the CDN’s content caching and distributed edge delivery. Drupal can integrate with origin-pull and origin-push CDNs. Cloud Platform Enterprise websites can use Edge. In addition, Acquia customers integrate with Level 3, AWS CloudFront, AT&T, and Edgio. The Drupal CDN module is a useful element for CDN integration.
Note for Cloud Platform users
A CDN’s operations can conflict with the operation of the Varnish cache on your Cloud Platform load balancer. If you want to use a CDN with your website, use Edge or contact Acquia Support to coordinate the integration. For more information, see Using a Content Delivery Network with Cloud Platform.
