2. Use Docker containers for consistent deployment across environments
3. Implement a CI/CD pipeline using Jenkins or GitLab CI
4. Use blue-green deployment strategy for zero-downtime updates
5. Set up automated database backups and disaster recovery procedures
6. Implement application monitoring using tools like New Relic or Datadog
7. Use a content delivery network (CDN) for faster global access
8. Implement auto-scaling for handling traffic spikes

Design Rationale

The chosen tech stack (React, Node.js, PostgreSQL) provides a robust and scalable foundation for building a real-time data visualization application. React's component-based architecture allows for modular and reusable UI elements, while Node.js enables efficient handling of real-time data streams. PostgreSQL offers reliable data storage with support for complex queries.

The use of WebSocket technology ensures real-time updates without constant polling, improving performance and user experience. D3.js or Chart.js are selected for their powerful data visualization capabilities, allowing for the creation of interactive and customizable charts and graphs.

The modular file structure and use of modern JavaScript practices (e.g., Redux for state management) promote code maintainability and scalability. The deployment strategy, including containerization and CI/CD, ensures reliable and consistent deployments while allowing for easy scaling and updates.
