Payment Boundary Decision Record
Context
In the pursuit of adopting a resilient architecture for payment processing in our system, it is imperative to delineate clear boundaries and dependencies among components. The boundaries ensure that changes in one part of the system do not cascade into other areas, particularly during the payment process that involves multiple integrations and potential failure points.
Decision
We will adopt a layered architecture that separates controllers, services, repositories, domains, and integrations. The payment processing will interface with an external payment gateway through defined ports, ensuring that the domain logic remains agnostic to external systems.
Alternatives
-
Tightly Coupled Architecture: Build tightly integrated components for payment processing.
- Pros: Simpler implementation, potential for fewer initial bugs.
- Cons: Difficult to maintain and extend, higher risk of failure cascading through the system.
-
Microservices Architecture: Implement payment as a microservice.
- Pros: Strong encapsulation, scalability, independent deployment.
- Cons: Increased complexity, potential latency in communication.
Consequences
By adopting this layered architecture with defined boundaries, we will achieve better isolation of changes, improve testability, and mitigate risks of failure in the payment process during integration with external APIs. This decision aligns with our goal of creating a resilient system capable of handling diverse transaction conditions while maintaining system integrity and user experience.
