About This Architecture

Three-tier Kubernetes microservices architecture with Redis caching and PostgreSQL persistence behind an Ingress Controller. Traffic flows from Ingress through three independent Microservice Deployments, each with dedicated Pods and Services connecting to shared Redis Cache and PostgreSQL StatefulSets. This pattern demonstrates production-ready stateful workload management with PersistentVolumeClaims ensuring data durability across pod restarts. Fork this diagram on Diagrams.so to customize service counts, add HPA autoscaling, or swap in your preferred database. Ideal for teams standardizing on Kubernetes-native data layer patterns.

How do I architect Kubernetes microservices with Redis caching and PostgreSQL database?

Deploy microservices as Deployments behind an Ingress Controller, with Redis and PostgreSQL as StatefulSets using PersistentVolumeClaims. This diagram shows three services sharing cached and persistent data layers.
