Benefits of employing an Anti-Corruption Layer in DDD:
1. Keeps the core domain pure: Imagine the core domain as the heart of your software system. It's responsible for the essential business logic and should be independent of external factors. An ACL acts as a protective layer, preventing external changes from directly affecting the core domain. This makes the core domain easier to understand, maintain, and test.
2. Makes the core domain easier to maintain: If the core domain is constantly being affected by changes in external systems, it becomes difficult to keep up with those changes and make necessary updates. An ACL isolates the core domain, allowing you to make changes without worrying about the ripple effects on external systems.
3. Makes the system more resilient: In the event of an external system failure, the ACL can prevent that failure from cascading into the core domain. This helps ensure that your system remains operational even if external systems are temporarily unavailable.
4. Makes it easier to integrate with outside systems: An ACL provides a structured and controlled way to connect the core domain to external systems. This ensures that the integrations are well-defined, consistent, and easy to maintain.
5. Makes the system more adaptable: As external systems evolve, their interfaces and data structures may change. An ACL acts as an adapter, allowing you to accommodate these changes without modifying the core domain. This keeps your system flexible and adaptable to changing external requirements.
