hexagonal-architecture

Hexagonal architecture decouples business logic by structuring applications with explicit ports and adapters, ensuring core domain rules remain independent of infrastructure concerns for enhanced maintainability.

Refactoring a monolith into modular components involves defining clear domain boundaries and using ports and adapters to orchestrate use cases, which separates core logic and facilitates integration efforts.

Domain-driven design with ports and adapters works by establishing explicit application boundaries that protect domain entities, coordinating logic across multiple environments while enforcing clean dependency rules.

Hexagonal architecture improves software testability by enforcing the separation of core business logic from infrastructure layers, allowing domain rules and use cases to be validated independently.

You need hexagonal architecture for software systems requiring decoupled layers, domain-driven design, or modular architecture, particularly when integrating diverse infrastructure layers or evolving complex domains.
