 The [Network Controller](/windows-server/networking/sdn/technologies/Software-Defined-Networking-Technologies#network-controller) provides a centralized, programmable point of automation to manage, configure, monitor, and troubleshoot virtual network infrastructure in your data center. The Network Controller must be deployed on its own dedicated VMs.
