The Kubernetes Cathedral: Why Enterprise Cloud-Native Platforms Need More Than a Cluster

This article argues that while Kubernetes provides the core orchestration for containerized workloads, an enterprise-grade platform demands comprehensive integration of identity, networking, GitOps, software supply-chain controls, certificate management, observability, resilience, cost governance, and operational ownership. It contrasts the basic cluster capabilities with enterprise-level decisions, emphasizing that managed services like AKS or EKS reduce infrastructure effort but do not create a complete internal developer platform. The goal is to build a governed platform product with secure defaults, repeatable delivery, and clear ownership, rather than assembling the largest toolchain.
