Adam Casella
Co-Founder and CTO at SnapRoute

Adam Casella co-founded SnapRoute in August, 2015, where he is responsible for setting technical direction and ensuring the operator’s perspective is always seen. Adam’s background of supporting networking products as a vendor, paired with his operational experience running large-scale data center networks gives him a unique perspective on how to build reliable, resilient, and easy-to-use products. Adam is an authority on both disaggregated and traditional networking technologies and especially their use in hyperscale spine/leaf CLOS designs and topologies. Prior to founding SnapRoute, Adam was responsible for designing and building hyperscale data center networks at Apple. This included the full spectrum of operations from product evaluation, proof-of-concept labs, overall topology design, configuration schemes, device deployment, and maintenance. Before Apple, Adam was a lead engineer in Cisco’s TAC on the LAN and Data Center Switching teams – giving him deep insight on silicon pipelines, hardware and software architecture, and a strong background in debugging and troubleshooting complex, multi-faceted technical issues. Adam has a BS in Network and Systems Administration from RIT (Rochester Institute of Technology).

Is Networking Ready for Cloud Native? An operators view on the need for a new NOS architecture.

Afternoon session

Disruptive innovation in networking is not going to come from “”yet another”” BGP stack or by adding more APIs to monolithic network operating systems. To date, the NOS architecture has been stretched beyond its original intent in an attempt to leverage modern orchestration and automation toolchains. As we move into the Cloud Native era, we need to evolve the core architecture of the NOS to embrace technologies that define Cloud Native – microservices, serviceability, and resiliency.

Using my years of experience running hyperscale environments at Apple, I can clearly see that networking cannot move forwarding using the approaches available today. Although disaggregation has facilitated networks to be more, open – it has stopped short of modernizing the NOS, thus not addressing the truly difficult problems that operators face in regards to automation, security and time to service.

The talk starts by sharing my firsthand experience with the challenges of running networks at scale with legacy approaches, including disaggregation. It finishes with an example of an alternative architectural model that looks to elevate the NOS towards the Cloud Native approach.
