Understand how Layer 7 load balancing uses rules and policies to evaluate HTTP and TERMINATED_HTTPS traffic for intelligent routing decisions.

Although you can implement layer 7 (L7) load balancing for any well-defined L7 application interface, L7 functionality for the Red Hat OpenStack Services on OpenShift (RHOSO) Load-balancing service (octavia) refers only to the HTTP and TERMINATED_HTTPS protocols and its semantics.

Neutron LBaaS and the Load-balancing service use L7 rules and policies for the logic of L7 load balancing. An L7 rule is a single, simple logical test that evaluates to true or false. An L7 policy is a collection of L7 rules and a defined action to take if all the rules associated with the policy match.
