 API Management supports the following load balancing options for backend pools:
 
-* **Round-robin**: By default, requests are distributed evenly across the backends in the pool.
-* **Weighted**: Weights are assigned to the backends in the pool, and requests are distributed across the backends based on the relative weight assigned to each backend. Use this option for scenarios such as conducting a blue-green deployment.
-* **Priority-based**: Backends are organized in priority groups, and requests are sent to the backends in order of the priority groups. Within a priority group, requests are distributed either evenly across the backends, or (if assigned) according to the relative weight assigned to each backend.    
-    > [!NOTE]
-    > Backends in lower priority groups will only be used when all backends in higher priority groups are unavailable because circuit breaker rules are tripped.

+| **Priority-based** | Backends are organized into priority groups. Requests are sent to higher priority groups first; within a group, requests are distributed evenly or according to assigned weights. |

+### Session awareness
 
 With any of the preceding load balancing options, optionally enable **session awareness** (session affinity) to ensure that all requests from a specific user during a session are directed to the same backend in the pool. API Management sets a cookie to maintain session state. This option is useful, for example, in scenarios with backends such as AI chat assistants or other conversational agents to route requests from the same session to the same endpoint.
 
-  > [!NOTE]
-  > Session awareness in load-balanced pools is being released first to the **AI Gateway Early** [update group](configure-service-update-settings.md).

+### Example
+
+Use the portal, API Management [REST API](/rest/api/apimanagement/backend), or a Bicep or ARM template to configure a backend pool. In the following example, the backend *myBackendPool* in the API Management instance *myAPIM* is configured with a backend pool. Example backends in the pool are named *backend-1* and *backend-2*. Both backends are in the highest priority group; within the group, *backend-1* has a greater weight than *backend-2*.
