🏗️ Architecture Patterns

Sistem mimarisi pattern'ları.

⚠️ Bu Skill vs design-patterns

Kural: Backend/sistem → bu skill, Frontend/UI → design-patterns

⚖️ Monolith vs Microservices

Seç:

• Monolith: Küçük takım, MVP, hızlı iteration
• Microservices: Büyük takım, bağımsız deploy

📚 Layered Architecture

Presentation → Application → Domain → Infrastructure

⚡ Event-Driven

Producer → Event Broker → Consumer
           (Kafka/SQS)

📊 CQRS

Command Service → Write DB
                    ↓ Events
Query Service ← Read DB

🧩 Modular Monolith

Modules separated by boundaries within a single deployable unit.
Good for: Teams growing from startup to scale-up phase.
Prevents "Distributed Monolith" chaos.

Aşama 1: Requirements Analysis

• Functional: Ne yapacak? (E-ticaret, Blog, IoT)
• Non-Functional: Scalability, Latency, Consistency ihtiyacı.
• Constraints: Takım boyutu, bütçe, timeline.

Aşama 2: Complexity Assesment

• Domain Complexity: Karmaşıksa -> DDD + Layered/Hexagonal.
• Scale Complexity: Yüksek trafik -> Event-Driven / Microservices.
• Data Complexity: Raporlama ağırsa -> CQRS.

Aşama 3: Pattern Selection

• Default: Modular Monolith ile başla.
• Scale-out: Bağımsız scale gereken modülleri ayır (Microservices).
• Real-time: Event-Driven ekle.
