Kubernetes microservices architecture with ingress-nginx routing HTTPS traffic to three independent services deployed across isolated namespaces. The Ingress Controller distributes requests to Service A, B, and C, each backed by a dedicated microservice pod, with HPA enabling automatic scaling based on demand. All microservices share access to external PostgreSQL and Redis data stores via Secrets, while NetworkPolicy enforces least-privilege communication between namespaces. This pattern demonstrates production-grade separation of concerns, secure credential management, and stateless service design for high-availability deployments.
