During Techfield Day 15 (TFD15) Cisco systems presented two major concepts. The first, integrating Kubernetes with Cisco ACI. The second, adopting OpenConfig to manage Service Provider WAN (SP-WAN). The overall theme is the concept of integrating open source solutions for traditional closed solutions and the value. Some of the delegates walked away understanding this is a confusing market. Cisco along with customers are still figuring out what hybrid-source environments interoperate and are managed.
