About This Architecture

Multi-namespace Kubernetes microservices architecture with ingress-nginx routing traffic across three independent service deployments in the default namespace. Users connect through the Ingress Controller, which distributes requests to Service A, B, and C, each backed by Deployments and Pods that communicate with a PostgreSQL StatefulSet in the data namespace and external Redis Cache. This pattern isolates workloads by namespace, enforces NetworkPolicy controls on ingress traffic, and demonstrates stateful data persistence using PersistentVolumes and PersistentVolumeClaims. Fork this diagram to customize namespace isolation, add RBAC policies, or extend with additional microservices and storage backends. The architecture exemplifies production-grade separation of concerns, enabling independent scaling and security policies per namespace.

How do I design a Kubernetes multi-namespace microservices architecture with ingress routing and persistent storage?

This diagram shows a production-grade Kubernetes setup where the ingress-nginx controller routes external traffic to three microservices (Service A, B, C) in the default namespace, while a PostgreSQL StatefulSet in the data namespace handles persistent data with PersistentVolumes. All services access external Redis Cache for caching, and NetworkPolicy enforces ingress security boundaries across na
