ddd-microservices

When to use this skill

Use this skill whenever the user wants to:

• Use DDD to define microservice boundaries (bounded contexts, aggregates, domain events)
• Design inter-service contracts and event-driven communication
• Implement cross-service consistency, querying, and operational strategies
• Decide between synchronous (REST/gRPC) and asynchronous (events/messaging) communication

How to use this skill

Workflow

1. Map bounded contexts to identify natural service boundaries
2. Define aggregates within each service for data consistency
3. Design communication: synchronous for queries and strong consistency; asynchronous (domain events) for decoupling
4. Ensure data ownership: each service owns its database; share data via APIs or events

1. Bounded Context to Service Mapping
