What role does Domain-Driven Design (DDD) play in microservices architecture?

Short answer: Domain-Driven Design (DDD) helps structure microservices around business domains.

Explain a bit more

It emphasizes: Bounded Contexts: Microservices align with natural business boundaries. Ubiquitous Language: Ensures a shared understanding of business concepts across the team. Aggregates: Group entities that are naturally consistent together under a single service boundary. Context Mapping: Defines how different microservices interact with each other. DDD provides the foundation for designing and organizing microservices based on real-world business requirements.

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
