The SD-WAN is abstracted from the hardware and create a virtual network overlay. This kind network is managed remotely from a central location. The benefit of SD-WAN is that you can remotely connect branches that are miles away to the network. The network is more flexible and available compared to the regular WAN.

That is a great benefit because the network for all the branches can be managed remotely from the headquarters without the need of employing extra IT personnel.
The SD-WAN is made up of three parts. The SD-WAN edge is the endpoint where the network reside can either be branches of braches. The SD-WAN orchestrator of the other hand manages the network virtually. The SD-WAN controller is the centralized management which set the polices to be executed by the orchestrator.

The main benefit of the on-premises SD-WAN is that you do not share sensitive information on the internet. On the other hand, the cloud-enabled SD-WAN connect a virtual gateway on the internet. It is beneficial because network is more accessible and has a higher performance.
SD-WAN is virtualized marketecture, and thus you do not need hardware for they specialized network functions. The main infrastructure of the SD-WAN is the commercial off-the-shelf equipment.
