ACI Design Principles: The role of SDN Overlays in Application Centric Deployments – Part 1

This is a two-part blog series developed in association with Tom Edsall, a Cisco Fellow and CTO of Insieme Networks, recently acquired by Cisco Systems. The intent is to elaborate on foundational design principles of Application Centric Infrastructure (ACI), a transformational approach for next-generation and cloud deployments. While the vision of ACI is an expansive one, this blog series focuses on the role of SDN overlays, their deployment con…
