Production-grade Kubernetes microservices architecture with three stateless services (service-a, service-b, service-c) fronted by an ingress-nginx controller and LoadBalancer, each scaled independently via HPA. Traffic flows from external users through the LoadBalancer to the Ingress Controller Pod, which routes requests via Ingress Resource to ClusterIP Services backing containerized deployments with multiple replicas. A dedicated data-tier namespace isolates Redis and PostgreSQL StatefulSets with persistent volumes, credentials managed via Secrets, and shared configuration via ConfigMap. RBAC controls (ServiceAccount, Role) and NetworkPolicy enforce least-privilege access across namespaces. This architecture demonstrates Kubernetes best practices: namespace isolation, stateful data separation, horizontal auto-scaling, and declarative security policies. Fork and customize this diagram on Diagrams.so to match your service topology, storage requirements, or multi-region failover needs. Consider adding a service mesh (Istio/Linkerd) for advanced traffic management and observability if your team requires canary deployments or distributed tracing.
