+#### Controlled rollout
+
+When deploying to Azure Kubernetes Service, you can use controlled rollout to enable the following scenarios:
+
+* Create multiple versions of an endpoint for a deployment
+* Perform A/B testing by routing traffic to different versions of the endpoint.
+* Switch between endpoint versions by updating the traffic percentage in endpoint configuration.

 #### IoT Edge devices
 
 You can use models with IoT devices through **Azure IoT Edge modules**. IoT Edge modules are deployed to a hardware device, which enables inference, or model scoring, on the device.

 - The Azure ML Model Registry captures all of the metadata associated with your model (which experiment trained it, where it is being deployed, if its deployments are healthy).
+- [Integration with Azure Event Grid](concept-event-grid-integration) allows you to act on events in the ML lifecycle. For example, model registration, deployment, data drift, and training (run) events.

 ## Retrain your model on new data
 
-Often, you'll want to update your model, or even retrain it from scratch, as you receive new information. Sometimes, receiving new data is an expected part of the domain. Other times, as discussed in [Detect data drift (preview) on datasets](how-to-monitor-datasets.md), model performance can degrade in the face of such things as changes to a particular sensor, natural data changes such as seasonal effects, or features shifting in their relation to other features.

 There is no universal answer to "How do I know if I should retrain?" but Azure ML event and monitoring tools previously discussed are good starting points for automation. Once you have decided to retrain, you should:
