As you can see, the landscape of controllers is pretty extensive at this point.

[Service Discovery](#ServiceDiscovery) and [Config Store](#ConfigStore) were already discussed above, so do not need more explanation here.

#### Mesh Config

* Automatic retrying of failed events (configurable)

The above logic is critical to handle correctly to ensure correctness of a controller.
The [Example Controller](../../pkg/kube/controllers/example_test.go) is a key reference point for any controller development;
