About This Architecture

Production-grade Kubernetes microservices architecture routes external traffic through an Ingress Controller to three independent services. Each service (Service 1, Service 2, Service 3) fronts its own microservice pod, all sharing a centralized Redis Cache Service and PostgreSQL Service for state management. The PostgreSQL Service connects to a StatefulSet backed by PersistentVolume for durable storage, while Redis Cache Pod provides ephemeral caching. This pattern demonstrates horizontal scaling, service discovery, and separation of stateless compute from stateful data layers.

How do I route external traffic to multiple microservices in Kubernetes with shared database and cache?

Use an Ingress Controller to route requests to individual Kubernetes Services, each fronting a microservice pod. All pods connect to shared Redis Cache Service and PostgreSQL Service backed by a StatefulSet with PersistentVolume for durable storage.
