Many networking or computing alternatives offer value in terms of lower cost (capital and operating cost). SD-WAN offers a good example. The classic engineering trade off for all IT or communications alternatives is pretty simple: “You can have it cheaper, faster, or better, pick two.”
SD-WAN promises to demolish that set of choices by allowing improvements on all three dimensions, especially for connecting remote locations and branch offices.
SD-WANs offer better agility (faster and simper deployment), better performance and reliability while also reducing costs.
Software-defined WANs, as the name suggests, abstract edge connectivity and also virtualize the WAN. In an overlay SD-WAN, new SD-WAN appliances are deployed on an existing routed network, either behind the routers or replacing them as the branch connection to the WAN, analysts at Nemertes Research note.
SD-WAN appliances also can collapse the typical branch stack by replacing other branch WAN appliances such as optimizers and firewalls.
In-network SD-WANs--often tied to Network Functions Virtualization--are more important for managed service approaches, and might be more attractive to enterprises that prefer to offload or outsource WAN management to third parties.

I have read a lot of blogs about SD WAN but yours is the one amoung very few who addressed the cost effective aspeect of SD WAN. kudus!!! Also if possible Read my article on SD-WAN and How Banking & Financial sector uses SDWAN and Cyber Hygiene for Startups
