Install and Configure Windows Server 2019 Azure Network Adapter

There are many new and exciting features found in Windows Server 2019 and many of these have to do with much more seamless and tighter cloud integration. Microsoft has done a great job of introducing new and improved functionality and tooling to assist organizations with their migrations to the public cloud as well as hybrid cloud which is certainly the most common scenario among enterprise environments today who have the need for resources existing both on-premises and in the public cloud. With the introduction of the Windows Admin Center, Microsoft has made possible a powerful utility that provides powerful integration with Windows Server 2019 and Microsoft Azure. One of the great new features in Windows Server 2019 for Azure integration is the Azure Network Adapter. In this post we will take a look at what the Azure Network Adapter is as well as how to install and configure Windows Server 2019 Azure Network Adapter.

What is the Azure Network Adapter?

The Azure Network Adapter is a new functionality built into the Windows Admin Center that allows creating a virtual network adapter in Windows Server 2019 that is essentially a direct VPN connection to your Microsoft Azure. The really great thing about this new feature is that Microsoft takes all the heavy lifting out of the solution by taking care of the complexities of the configuration between your server and Azure all within the GUI, wizard driven interface of the Windows Admin Center.

This provides an extremely easy way to make a connection between a Windows Server 2019 workload on-premises to your Microsoft Azure environment. There are many different use cases this may fit, however, if you did not have the need to setup a site-to-site VPN connection between your on-premises environment and Microsoft Azure, this is a perfect fit for the Azure Network Adapter and the VPN connection it creates on the server itself. This might certainly come in handy in an edge environment without much network or other infrastructure. Creating a connection to your Azure resources would be easily accomplished in this edge environment with the Azure Network Adapter.

Wrapping Up

The Azure Network Adapter is a great way to have point to site connectivity to your Azure environment. If you need across the board access from on-premises, you will probably want to use a site-to-site VPN connection, however, for one off or special use cases such as in edge environments, the Azure Network Adapter is an easy way to have access to your Azure resources/networks.
