+## Use Azure Container Instances (ACI)
+
+Azure Container Instances are dynamically created when deploying a model. To enable Azure Machine Learning to create ACI inside the virtual network, you must enable __subnet delegation__ for the subnet used by the deployment.
+
+To use ACI in a virtual network to your workspace, use the following steps:
+
+1. To enable subnet delegation on your virtual network, use the information in the [Add or remove a subnet delegation](../virtual-network/manage-subnet-delegation.md) article. You can enable delegation when creating a virtual network, or add it to an existing network.
+
+    > [!IMPORTANT]
+    > When enabling delegation, use `Microsoft.ContainerInstance/containerGroups` as the __Delegate subnet to service__ value.
+
+2. Deploy the model using [AciWebservice.deploy_configuration()](https://docs.microsoft.com/python/api/azureml-core/azureml.core.webservice.aci.aciwebservice?view=azure-ml-py#deploy-configuration-cpu-cores-none--memory-gb-none--tags-none--properties-none--description-none--location-none--auth-enabled-none--ssl-enabled-none--enable-app-insights-none--ssl-cert-pem-file-none--ssl-key-pem-file-none--ssl-cname-none--dns-name-label-none--primary-key-none--secondary-key-none--collect-model-data-none--cmk-vault-base-url-none--cmk-key-name-none--cmk-key-version-none--vnet-name-none--subnet-name-none-), use the `vnet_name` and `subnet_name` parameters. Set these parameters to the virtual network name and subnet where you enabled delegation.

 ## Use Azure Firewall
 
 When using Azure Firewall, you must configure a network rule to allow traffic to and from the following addresses:
