The market for SD-WAN has been driven in part by its ability to reduce bandwidth costs and improve the performance of cloud access. Traditionally, Wide Area Networks (WANs) and network security were loosely coupled entities. This amicable live-and-let-live separation falls apart with todays SD-WAN.

For a while now, there have been two basic SD-WAN solutions offering a choice between DIY (appliance-based) or fully managed (service-based) solutions. Being at opposite ends of the spectrum, customers are increasingly preferring an SD-WAN solution that encompasses the advantages of both solutions.

As I discussed in my previous blog , few companies, especially global organizations, have Internet access at every branch. UCaaS traffic must be backhauled across the WAN to Internet access point resulting in inefficient traffic routing for voice and video calls, and potential quality issues related to excessive delay and jitter.

With any new technology theres fake news and SD-WANs are no exception. Its true, SD-WANs probably wont reduce your WAN costs by 90 percent or make WANs so simple a 12-year old can deploy them. SD-WANs allow us to do the same with the WAN. It was an arcane art and CCIEs were the master craftsman of the trade.
