Learn how to use the Microsoft Azure Network Adapter (MANA) component of Azure Boost to improve the performance and availability of virtual machines (VMs) in Azure. MANA is a next-generation network interface that provides stable forward-compatible device drivers for Windows and Linux operating systems. MANA hardware and software are engineered by Microsoft and take advantage of the latest advancements in cloud networking technology.

MANA maintains feature parity with previous Azure networking features. VMs run on hardware with both Mellanox and MANA NICs, so existing `mlx4` and `mlx5` support still need to be present.
