🏛️ Architectural Styles
1. 🎯 Learning Objectives
- Compare architectural styles with trade-offs
- Design microservices decomposition
- Apply event-driven patterns
2. 📖 Core Content
3.1 Layered Architecture
Presentation → Business Logic → Persistence → Database Pros: Separation of concerns, testability, clear dependencies. Cons: Performance overhead, potential for tight coupling between layers.
3.2 Microservices
Each service: independently deployable, owns data, communicates via APIs. Pros: Independent scaling, team autonomy, technology flexibility. Cons: Distributed complexity, network overhead, data consistency challenges.
3.3 Event-Driven Architecture
Components communicate asynchronously via events. Decoupled, scalable, good for real-time systems. Pattern: Event → Event Bus → Event Handlers
