Use a Content Delivery Network (CDN)

Drupal's best Content Delivery Network integration module is written by Wim Leers as part of his bachelor  thesis. It is compatible with push and pull setups. A content delivery network does two things.

  • takes the load off your dynamic server (PHP-MySQL-Apache);
  • serves static files from servers geographically closest to the user

Advantages

  • Reduced dynamic server load
