Diagram Library
Reference diagrams for common architectural patterns — system topologies, data flow diagrams, sequence charts, and decision trees embedded in articles throughout this library.
Architecture Style Diagrams
Microservices Topology
API gateway, service mesh, service registry, and inter-service communication topology.
Event-Driven Architecture Flow
Producers, event broker, consumer groups, and downstream projections.
CQRS Command / Query Split
Command stack with write model, event projection, and separate read model / query side.
Hexagonal (Ports & Adapters)
Domain core surrounded by ports and adapter implementations for each external concern.
Reliability Pattern Diagrams
Circuit Breaker State Machine
Closed → Open → Half-Open state transitions with timeout and success threshold.
Saga Orchestration Flow
Orchestrator service coordinating local transactions and compensating actions on failure.
Data Architecture Diagrams
Lakehouse Architecture
Bronze / Silver / Gold medallion layers with Delta Lake and Spark compute.
Transactional Outbox Flow
Atomic DB write + outbox table, relay poll / CDC, and broker publication sequence.
