Oracle Traffic Director is a fast, reliable, and scalable layer-7 software load balancer. You can set up Oracle Traffic Director to serve as the reliable entry point for all HTTP, HTTPS and TCP traffic to application servers and web servers in the back end. Oracle Traffic Director distributes the requests that it receives from clients to servers in the back end based on the specified load-balancing method, routes the requests based on specified rules, caches frequently accessed data, prioritizes traffic, and controls the quality of service.
The architecture of Oracle Traffic Director enables it to handle large volumes of application traffic with low latency. The product is optimized for use in Oracle Exalogic Elastic Cloud and Oracle SuperCluster. It can communicate with servers in the back end over Exalogic's InfiniBand fabric. For more information about Exalogic, see the Oracle Exalogic Elastic Cloud documentation, http://docs.oracle.com/cd/E18476_01/index.htm. Oracle Traffic Director is also certified with various Fusion Middleware products.
Oracle Traffic Director is easy to install, configure, and use. It includes a simple, wizard-driven graphical interface as well as a robust command-line interface to help you administer Oracle Traffic Director instances.
For high availability, you can set up pairs of Oracle Traffic Director instances for either active-passive or active-active failover. As the volume of traffic to your network grows, you can easily scale the environment by reconfiguring Oracle Traffic Director with additional back-end servers to which it can route requests.
Depending on the needs of your IT environment, you can configure Oracle Traffic Director to apply multiple, complex rules when distributing requests to the back-end servers and when forwarding responses to clients.
