Explore the intricacies of enabling secure microservices communication in Kubernetes without relying on a service mesh in this 33-minute conference talk by Evan Anderson from VMware. Delve into the platform's native primitives and learn how technologies like NetworkPolicy, token projection, API gateways, cert-manager, and language runtimes interact. Examine authentication options, encryption methods, rate limiting techniques, and multi-tenant infrastructure services while considering both L4 and L7 features. Gain insights into compliance requirements and developer-friendly practices. Drawing from his experience as Knative Security Working Group lead, Anderson provides valuable knowledge on building without a service mesh and offers a deeper understanding of the benefits service meshes bring to the table.
