✅ Follow These Best Practices: - Design for scalability and performance - Implement security by design - Design for fault tolerance and resilience - Implement comprehensive monitoring - Design for maintainability and extensibility

!!! tip Start Small Begin with a simple architecture and evolve it as your needs grow. Don't over-engineer from the start.

!!! note Security First Always prioritize security in architecture decisions. Implement security controls at every layer.
