While Software Defined Wide Area Networking (SD WAN) promises to simplify the view of a network and automate many of the functions of implementing and managing it, the underlying complexity of the physical network does not change. That is why organizations are turning to managed SD WAN providers to maintain their networks.
When implementing an SD WAN device for the first time at a site, for example, an organization cannot send the device there and ask someone to implement it – technical knowledge is still required.
The WAN is a critical resource and an engineer is still required to deploy it properly in SD WAN implementations. The engineer will have to co-ordinate the disconnection and connection of the device, make sure it’s connected to the correct port, perform testing and any remedial work and interact with the network team to ensure it is installed correctly.
