The key points: 1. **Each context has its own model and language**, which matches the idea of an independent microservice. 2. **Explicit interaction boundaries** (through contracts, events, APIs) make it possible to build loosely coupled services. 3. **No shared databases**: each service manages its own aggregate and data. 4. **Isolation of change**: business rules inside one context can change without breaking the others. **Summary:** DDD shows *where a system's natural semantic boundaries lie*, and therefore *where microservices should end*.For the reviewerNote to the moderator (optional)Visible only to the moderator.
