Define bounded contexts by applying Domain-Driven Design to separate domain boundaries, establish team autonomy, and clarify contracts between microservices. This ensures cohesive service responsibilities and clear contextual separation within complex software architectures.

Design aggregates and enforce invariants within each bounded context using Domain-Driven Design to ensure transactional consistency and data integrity. This approach guarantees that all state changes within an aggregate satisfy defined business rules.

Domain events and integration events enable resilient information exchange between bounded contexts. Domain events handle internal aggregate state changes, while integration events propagate these changes across different services to maintain event-driven behavior.

You need Domain-Driven Design when structuring complex subject domains that require clear domain boundaries, cohesive aggregate management, and consistent event-driven behavior across autonomous services to maintain transactional consistency.

Start by identifying bounded contexts, then draft corresponding aggregates and invariants to ensure data integrity, and finally define domain and integration events to establish resilient communication between contexts.

Yes, you can apply DDD to ensure transactional consistency guarantees across distributed services. By enforcing invariants within aggregates and defining integration events, the architecture maintains reliable and consistent event-driven behavior.
