The Network Controller provides a centralized, programmable point of automation to manage, configure, monitor, and troubleshoot virtual network infrastructure in your data center. It is a highly scalable server role that uses Service Fabric to provide high availability. The Network Controller must be deployed on its own dedicated VMs.

Deploying Network Controller enables the following functionalities:

• Create and manage virtual networks and subnets. Connect virtual machines (VMs) to virtual subnets.
• Configure and manage micro-segmentation for VMs connected to virtual networks or traditional VLAN-based networks.
• Attach virtual appliances to your virtual networks.
• Configure Quality of Service (QoS) policies for VMs attached to virtual networks or traditional VLAN-based networks.
