ADR for Payment Boundary
Context
In developing a payment processing system, defining clear boundaries between various components is critical for maintaining a robust architecture. This delineation ensures that payment interactions can evolve independently and that the overall system remains resilient against failures.
Decision
We have decided to implement a domain-driven design where the payment processing logic resides within the domain layer, while integration with external payment gateways will occur via an adapter pattern, ensuring that the domain is insulated from external dependencies.
Alternatives
- Tight Coupling with External Service: Directly invoking external payment services from the domain layer, leading to increased risk of failure.
- Service Layer Gateway: Using a service layer to aggregate responses but still indirectly coupling the domain to the external service.
Consequences
By using an adapter pattern, the domain can adapt to different payment gateways without affecting other parts of the system. This promotes better maintainability and flexibility in the payment processing architecture.
