Architecture Patterns
Master proven backend architecture patterns including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design to build maintainable, testable, and scalable systems.
When to Use This Skill
- Designing new backend systems from scratch
- Refactoring monolithic applications for better maintainability
- Establishing architecture standards for your team
- Migrating from tightly coupled to loosely coupled architectures
- Implementing domain-driven design principles
- Creating testable and mockable codebases
- Planning microservices decomposition
Core Concepts
1. Clean Architecture (Uncle Bob)
Layers (dependency flows inward):
- Entities: Core business models
- Use Cases: Application business rules
- Interface Adapters: Controllers, presenters, gateways
- Frameworks & Drivers: UI, database, external services
Key Principles:
- Dependencies point inward
- Inner layers know nothing about outer layers
- Business logic independent of frameworks
- Testable without UI, database, or external services
2. Hexagonal Architecture (Ports and Adapters)
Components:
- Domain Core: Business logic
- Ports: Interfaces defining interactions
- Adapters: Implementations of ports (database, REST, message queue)
Benefits:
- Swap implementations easily (mock for testing)
- Technology-agnostic core
- Clear separation of concerns
3. Domain-Driven Design (DDD)
Strategic Patterns:
- Bounded Contexts: Separate models for different domains
- Context Mapping: How contexts relate
- Ubiquitous Language: Shared terminology
Tactical Patterns:
- Entities: Objects with identity
- Value Objects: Immutable objects defined by attributes
- Aggregates: Consistency boundaries
- Repositories: Data access abstraction
- Domain Events: Things that happened
