An application delivery controller is a device that is typically placed in a data center between the firewall and one or more application servers (an area known as the DMZ).

The latest generation of application delivery controllers, such as the F5 BIG-IP® product family, handles a much wider variety of functions, including rate shaping and SSL offloading, as well as serving as a Web application firewall.
