+- End-to-end TLS encryption for compliance scenarios requiring encryption to the backend.
 - Autoscaling to dynamically adjust capacity as your web traffic load change.
 - Connection draining allowing graceful removal of backend pool members during planned service updates.
 - Session stickiness to ensure client requests in the same session are routed to the same backend server.
