About This Architecture

Three-tier microservices architecture on Kubernetes with shared Redis cache and PostgreSQL database demonstrates production-grade service mesh patterns. External traffic flows through an Ingress Controller to three independent microservices (MS1, MS2, MS3), each deployed as separate Deployments with dedicated Pods and Services within a single App namespace. All microservices connect to a centralized Redis Service for caching and a PostgreSQL StatefulSet with persistent volume claims for durable data storage. This architecture enables independent scaling, rolling updates, and fault isolation while maintaining shared state through Redis and PostgreSQL.

How do I architect microservices on Kubernetes with shared Redis cache and PostgreSQL database?

Deploy each microservice as a separate Deployment with dedicated Pods and Services within a namespace, route external traffic through an Ingress Controller, and connect all microservices to centralized Redis Service for caching and PostgreSQL StatefulSet with PVCs for persistent data storage.
