topologies mix and match these two.

For a standard Kubernetes deployment, both CA and discovery will use JWT authentication, with a token automatically

## Controllers

Istiod consists of a collection of controllers. Per Kubernetes, "controllers are control loops that watch the state of your cluster, then make or request changes where needed."
