## 🏛️ Architectural Patterns

### 1. Layered Architecture
- **Separation of Concerns**: Each layer has distinct responsibilities
- **Abstraction**: Higher layers use lower layers through well-defined interfaces
- **Modularity**: Components can be developed and tested independently
- **Scalability**: Layers can be scaled independently based on load

### 2. Event-Driven Architecture
- **Asynchronous Processing**: Non-blocking operations for better performance
- **Loose Coupling**: Components communicate through events
- **Scalability**: Easy to add new event handlers
- **Resilience**: System continues operating even if some components fail

### 3. Microservices Pattern
- **Service Independence**: Each component can be deployed independently
- **Technology Diversity**: Different components can use different technologies
- **Fault Isolation**: Failures in one service don't affect others
- **Scalability**: Services can be scaled based on individual needs

### 4. Circuit Breaker Pattern
- **Fault Tolerance**: Prevents cascading failures
- **Quick Recovery**: Automatic recovery when services become available
- **Monitoring**: Provides insights into service health
- **Graceful Degradation**: System continues with reduced functionality
