 You can also [enable Azure Private Link](how-to-configure-private-link.md) to connect to your workspace using a private endpoint. The private endpoint is a set of private IP addresses within your virtual network. [Learn how to set up this private endpoint.](how-to-configure-private-link.md)

+> You can combine virtual network and Private Link together to protect communication between your workspace and other Azure resources. However, some combinations require an Enterprise edition workspace. Use the following table to understand what scenarios require Enterprise edition:

+> Azure Machine Learning does not support using an Azure Kubernetes Service that has private link enabled. Instead, you can use Azure Kubernetes Service in a virtual network.
