5. Deploy the PostgreSQL database using a managed service (e.g., AWS RDS)
6. Set up Nginx as a reverse proxy and for serving static assets
7. Implement auto-scaling based on traffic and resource utilization
8. Use a CDN (e.g., Cloudflare) for global content delivery
9. Set up monitoring and logging (e.g., ELK stack or Prometheus/Grafana)
10. Implement regular database backups and disaster recovery procedures

Design Rationale

The Newsletter Builder application is designed with a focus on user experience, scalability, and modern web development practices. React was chosen for the frontend due to its component-based architecture, which aligns well with the modular nature of newsletter templates. The drag-and-drop functionality is central to the user experience, making template customization intuitive and accessible to non-technical users.

Node.js and Express were selected for the backend to maintain a JavaScript ecosystem throughout the stack, facilitating faster development and easier knowledge sharing among team members. PostgreSQL provides a robust, relational database system capable of handling complex queries and relationships between users, templates, newsletters, and subscribers.

The deployment strategy leverages containerization and Kubernetes for scalability and ease of management. This approach allows for efficient resource utilization and simplified updates. The use of a CDN and global cloud infrastructure ensures fast loading times for users worldwide, enhancing the overall user experience.
