🏗️ Architecture Patterns

Sistem mimarisi pattern'ları.

⚠️ Bu Skill vs design-patterns

Bu Skill	design-patterns
Sistem mimarisi	UI/UX tasarım
Microservices, CQRS	Z-index, shadows
Database, scaling	Animation, spacing

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

---

⚖️ Monolith vs Microservices

Aspect	Monolith	Microservices
Complexity	Düşük	Yüksek
Scaling	Tüm uygulama	Service bazlı
Team Size	Küçük	Büyük

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.

🔄 Workflow

Kaynak: Software Architecture Guide

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.

Kontrol Noktaları

Aşama	Doğrulama
1	Gereksinimler net (NFRs belirlendi)
2	Seçilen pattern probleme uygun (Over-engineering değil)
3	Takım bu mimariyi yönetebilir
