Currently, I have a `frontend` , `backend` , and `tf-serving` service. My current configuration exposes both `frontend` and `backend` services outside.

The service `tf-serving` , however, is an internal service only used by the `backend` service. They communicate using the gRPC API provided by TensorFlow Serving.

Would it be possible for `tf-serving` to be load balanced too such that when I call it from the `backend` service, Traefik will load balance it for me?

BTW: I deploy these containers on a docker swarm with 10 VMs.
