Clean Architecture suits complex domains needing strict layer separation, while a Modular Monolith fits larger teams wanting isolated modules without distributed deployment overhead. Choose based on your domain complexity and team size to ensure long-term maintainability.

Hexagonal Architecture organizes application logic around ports and adapters, isolating the core domain from external concerns like databases and UI. This reduces coupling and allows you to swap infrastructure components without modifying business rules.

Vertical Slice Architecture organizes code by feature rather than technical layers, grouping all related components together. It is the best approach for smaller teams needing rapid iteration without the overhead of strict boundary enforcement found in complex patterns.

Decide on a software architecture pattern by evaluating domain complexity, team size, and maintenance goals. Use canonical structures and decision criteria to match patterns like Clean Architecture or Vertical Slice to your specific scalability requirements.

Yes, you can apply these architecture patterns to reduce coupling in existing applications by defining canonical structures and strict boundaries. Refactoring toward a Modular Monolith or Hexagonal pattern helps isolate features and improve long-term maintainability.
