## What it is
A sample order fulfillment application demonstrating microservices, event-driven architecture, and domain-driven design with multiple concrete implementation alternatives (Kafka, REST, Zeebe/Camunda). It is educational code written in Java/Spring Boot to be explained, not production-ready.

## Use cases
- learn microservices architecture with a concrete example
- compare kafka vs rest vs zeebe communication between services
- understand event-driven architecture and long-running services
- see how to use a workflow engine inside a microservice
- study domain-driven design with sample code
- learn stateful resilience patterns like stateful retries

## When to choose
- you want hands-on example code for microservices and event-driven design
- you are evaluating workflow engines like Camunda 8/Zeebe in Java services
- you are teaching or learning DDD and EDA concepts

## When to avoid
- you need production-ready, best-practice code to copy into your system
- you work outside the Java/Spring Boot ecosystem
- you need a maintained framework rather than a demonstration sample

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: microservices, message-queue, workflow-automation, rpc
- domain: microservices, developer-tools, tutorials
- platform: jvm, cross-platform
- tags: event-driven-architecture, domain-driven-design, camunda, zeebe, apache-kafka, spring-boot, sample-application, orchestration, docker
