Scaling Considerations

Node.js scales horizontally well. Use clustering or container orchestration for multi-core utilization. Consider serverless for variable workloads.

Security Considerations

Validate all inputs, use helmet for security headers, implement rate limiting, keep dependencies updated, use npm audit regularly.

Performance Optimization

Use streaming for large files, implement connection pooling, cache aggressively with Redis, profile with clinic.js, optimize event loop usage.
