 In this example we use the [VirtualServer and
 VirtualServerRoute](https://docs.nginx.com/nginx-ingress-controller/configuration/virtualserver-and-virtualserverroute-resources/)
 resources to configure load balancing for the modified cafe application from the [Basic
 Configuration](../basic-configuration/) example. We have put the load balancing configuration as well as the deployments
-and services into multiple namespaces. Instead of one namespace, we now use three: `tea`, `coffee`, and `cafe`.

-- In the tea namespace, we create the tea deployment, service, and the corresponding load-balancing configuration.
-- In the coffee namespace, we create the coffee deployment, service, and the corresponding load-balancing configuration.
-- In the cafe namespace, we create the cafe secret with the TLS certificate and key and the load-balancing configuration
-  for the cafe application. That configuration references the coffee and tea configurations.
