Architecture Overview

System Design

This homelab implements a modern data platform on Kubernetes with the following layers:

Infrastructure Layer

• Kubernetes cluster
• Flux CD for GitOps
• Rook/Ceph for storage
• Networking and ingress

Data Layer

• Object storage (lakehouse)
• Databases
• Data catalog
• Processing engines

Application Layer

• Development tools (VS Code Server)
• Authentication (Keycloak)
• User applications

Observability Layer

• Metrics collection
• Logging
• Alerting

Design Principles

• GitOps: All configuration in Git
• Declarative: Infrastructure as code
• Scalable: Designed to grow
• Observable: Full visibility into system state
