You can now use Windows Admin Center (preview) in the Azure portal to manage the Windows Server operating system inside an Azure VM. Manage operating system functions from the Azure portal as well as work with files in the VM without using Remote Desktop or PowerShell.
The management PC or other system that you use to connect to the Azure portal has the following requirements:
The Microsoft Edge or Google Chrome web browser
Access to the virtual network that's connected to the VM (this is more secure than using a public IP address to connect). There are many ways to connect to a virtual network, including by using a VPN gateway.
