There is arguably no networking technology surrounded by more hype than software defined WANs (SD-WAN), and much of it is well deserved.
A significant number of network professionals either have an SD-WAN deployment underway or on their near-term roadmap. The reason is that SD-WAN architecture is optimized for cloud computing while legacy WANs were designed when client-server computing was the norm.
As work-from-home has shifted more apps to the cloud, the adoption of SD-WAN has accelerated.
