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.
