I don’t “get” SD-WAN

This might be a stupid post but I’m struggling to really understand the purpose and power of SD-WAN. I’ve tried to search YouTube for real world examples of SD-WAN in action and see how people actually configure it but all I see is a bunch of marketing wank and slideshows with cloud diagrams all over them.

Is it basically just a fancy GUI that sits on top and cranks out standard configurations? Does it really do anything that can’t be achieved by knowing correct syntax and properly building a network? Is it aimed at organizations that may not have a full time network engineer?

Basically what does it truly achieve that can’t be done by other means.
