# Event-Driven Architecture: CQRS, Event Sourcing, and Saga Patterns
> Practical architectural guidance for production systems.
## Overview
Modern software architecture requires careful consideration of scalability, reliability, and maintainability.
## Key Principles
- Separation of concerns
- Loose coupling, high cohesion
- Fail fast and gracefully
- Design for observability
## Architecture Patterns
- Layered architecture
- Hexagonal architecture
- Event-driven architecture
- Microservices patterns
## Implementation
```typescript
interface ArchitecturePattern {
name: string;
benefits: string[];
tradeoffs: string[];
useCases: string[];
}
```
