Support for multiple NICs and subnet mapping for Azure VM

Previously, Machine Creation Services (MCS) supported single NIC on Azure. With this feature, you can now create a VM with multiple NICs. You can also associate multiple NICs on a VM to multiple subnets. Please note that the subnets must all reside in the same virtual network (vNet).

If you use the machine profile workflow, NIC properties, such as accelerated networking, in master VM or ARM template spec are captured and copied to the corresponding NIC of the created VM.

You can add or delete NICs based on the maximum number of NICs supported by the VM size. Additionally, the NIC assignment on existing VMs can also be updated.
