Any good CDN integration with Drupal?
Drupal 7 has robust CDN integration with a number of options. You can consider the Storage API module for S3 integration among others.


  Storage API is a low-level framework for managed file storage and serving.


Also consider the CDN module.


  This module provides easy Content Delivery Network integration for Drupal sites. It alters file URLs, so that files are downloaded from a CDN instead of your web server.
