Traditional hub-and-spoke networks and discrete security boxes are buckling under three simultaneous shifts: cloud application architectures, a work-from-anywhere workforce, and latency-sensitive edge use cases. Distributed Cloud Networking (DCN) is an architectural response—an expansion of SASE that extends networking and security from branches and users into cloud and edge, unifying policy and telemetry across on-prem, multicloud, and the “cloud middle.” DCN blends three pillars—SASE, WAN-as-a-Service, and multicloud networking software—into a service-centric, elastic fabric with zero-trust enforcement, context-based visibility, and automation at its core. This webcast lays the foundation: what DCN is (and is not), why legacy approaches fall short, and how to think about high-level adoption patterns, operating models, and success metrics. Framed from an industry analyst perspective, the session is vendor-neutral and sets the stage for future, deeper dives on design and migration. The story that played out for servers in public cloud is now arriving for enterprise networking and security.
