+Octavia is known as an *operator-scaled* load balancing service, whose primary goal is to
+distribute incoming network traffic, destined for a single VM, across multiple VMs instead;
+thus preventing overloading the VM and improving the overall performance of the VM's outbound

 changed to make them highly available and have two Amphora VM per service. Done by setting
 ``octavia_loadbalancer_topology: "ACTIVE_STANDBY"`` in ``${KAYOBE_CONFIG_PATH}/kolla/globals.yml``,
 this will ensure that if the master Amphora VM were to go down, the other would be able to
 take over the load balancing functions.
