Over on virtualizedgeek.com, I struggled to find the killer application for Software-Defined Networking. The PacketPushers who are the geekiest of networking geeks don't feel Cisco ACI or VMware NSX are mature enough for the average enterprise. I am however intrigued by SD WAN. One of the use cases I've mentioned for SD-WAN is saving on circuit costs while improving network service levels. Another use case is segmentation which is what I talk about in this episode.
