IDG Contributor Network: The new branch office SD-WAN model
8 August 2017, 2:00 pm



Wrapping up an SD-WAN workshop session with a client last week, I reflected on how rapidly the branch office WAN connectivity and management model is changing. Some great opportunities are emerging for enterprise IT teams that can materially impact how the network is designed, paid for and managed. Here are some thoughts:

1. Public cloud is driving a lightweight edge security model

Most people agree that SD-WAN can facilitate service chaining, and a selective backhaul model is interesting to many enterprises that want to concentrate next-generation firewall services in larger locations. But with the rapid growth of distributed content in public cloud applications (even from Microsoft and Salesforce, who long resisted this trend that Google pioneered) it’s increasingly counterproductive to backhaul browsing traffic long distances from the end users. It reduces performance, and adds significant load at hubs on the network — not ideal when this can represent 80 percent or more of the traffic.
