Watch a conference talk exploring how micro-segmentation and multi-tenancy serve as critical indicators of platform engineering success, similar to Van Halen's famous brown M&Ms contract clause. Discover key requirements for internal developer platforms serving multiple workloads while balancing security and cost considerations. Learn about different Kubernetes deployment approaches, from single-tenant clusters to shared namespaces-as-a-service architectures. Examine real-world implementations of multi-tenancy and micro-segmentation in cloud native systems, with demonstrations of automated solutions using GitOps and Policy as Code. Understand how these architectural decisions impact application component communication within shared infrastructure and their implications for platform engineering teams.
