architecture-patterns

Select architectural patterns by evaluating your web application's scale, data flows, and team familiarity. Guide pattern selection across the product lifecycle from concept to deployment, enforcing coverage of MVC, layered architecture, and microservices for robust design.

CQRS separates command and query responsibilities for optimized data flows, while event-driven architecture manages asynchronous communication between services. Both distributed architecture patterns are covered to help you design scalable systems based on specific data flow requirements.

Use hexagonal architecture, or Ports and Adapters, when you need strict separation of core logic from external dependencies for enhanced testability. Choose layered architecture when a simpler N-Tier structure is sufficient for your product's current scale and data flows.

MVC design is often better for small web apps due to team familiarity and simpler data flows. Microservices patterns apply to scalable distributed systems where you need independent service deployment and robust separation of concerns across the product lifecycle.

Event-driven architecture limitations include increased complexity in tracing data flows and managing asynchronous events across distributed systems. Consider CQRS or hexagonal architecture as alternative patterns when transaction consistency and testability are more critical than decoupled scalability.
