System Architecture Patterns

Purpose

Apply proven architectural patterns to create maintainable, scalable systems with clear separation of concerns and well-defined component responsibilities.

When to Use

Designing new systems or major features
Refactoring existing architecture
Solving common architectural challenges
Organizing complex codebases

Key Capabilities

Pattern Selection - Choose appropriate patterns for the problem
Component Design - Define clear boundaries and responsibilities
Integration Planning - Design how components communicate

Approach

Understand the problem domain and requirements
Identify architectural concerns (scalability, maintainability, etc.)
Select patterns that address those concerns
Define component boundaries and interfaces
Document pattern application and rationale

Example

Context: Web application with business logic and data access

Pattern: Layered Architecture

Presentation Layer (UI)
    ↓
Business Logic Layer (Services)
    ↓
Data Access Layer (Repositories)
    ↓
Database

Benefits:

Clear separation of concerns
Easy to test each layer independently
Can swap implementations (e.g., different databases)

Best Practices

✅ Choose patterns that solve actual problems
✅ Document why you chose each pattern
✅ Keep it simple - don't over-architect
❌ Avoid: Using patterns just because they're popular
