back to the ``flyteadmin`` service in the control plane.

The ``catalog`` service runs in the control plane and is used when caching is enabled. Note that ``catalog`` is
not exposed via the ingress by default and does not have its own authentication mechanism. The ``catalog`` service
in the control plane cluster can for instance be made available to the ``flytepropeller`` services in the data plane
clusters with an internal load balancer service (see e.g. `GKE documentation <https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#create>`_
or `AWS Load Balancer Controller <https://kubernetes-sigs.github.io/aws-load-balancer-controller/latest/guide/service/nlb/>`_).
