Explore container networking in this 34-minute conference talk that untangles service meshes and Software-Defined Networks (SDNs). Dive into the comparison of three service meshes - Istio, Linkerd, and Conduit - against a traditional SDN like OpenContrail within a Kubernetes cluster environment. Examine the features of each product and their Kubernetes integrations. Gain insights into how horizontally scalable applications require reliable and scalable networking, accurate traffic routing, and security policy enforcement. Understand the evolving landscape where service meshes are increasingly encroaching on traditional SDN territory, and learn how these technologies address the networking challenges in modern containerized environments.
