Systems Engineering Life

This topic has been covered extensively by experts. What has not been covered in my opinion, is the underlying and fundamental change of transport infrastructure and specially power. The traditional WAN transport mechanisms are solid in terms of power normalization all through the last mile.  With the new (or not so new) shift towards commercially available Internet connections (namely DSL and Cable), customers need to watch out for excessive power coming through those lines and the respective modems and into their edge devices. There are surge protectors out there with "ethernet in/out" ports which could be used to mitigate this problem. Happy conversation out there...

I am sure at this point, you all have caught up on with this SD-WAN craze.  Some early vendors are now bought by industry giants.  Some have really cool cloud provisioning and management dashboards. Some claims that your edge has never been this simple to set up before. However, there are still a few concerns I have: VPN technology is a mature one by now.  There are vendors out there who can offload IPsec tasks and processes onto a hardware based processor.   Would these new "SD-WAN" providers give me the same throughput/granularity? How scalable is the solution? Applications - There are vendors out there who did WAN Optimization for living and have a very rich application signature database.  What about the pure play vendors? Same goes for routing.  can you handle complex routing? can you offload or optimize those touting decisions? What if I already have that infrastructure (VPN/Routing) in place? would your solution be a tunnel in tunnel? What would
