8. Implement AWS Certificate Manager for SSL/TLS
9. Configure auto-scaling groups for handling traffic spikes
10. Use AWS CodePipeline for continuous integration and deployment

Design Rationale

The chosen tech stack (React, Node.js, PostgreSQL) offers a balance of performance, scalability, and developer productivity. React's component-based architecture allows for modular UI development, while Node.js provides a JavaScript-based backend for code reuse. PostgreSQL offers robust data storage for user information and caching solar event data.

D3.js was selected for visualizations due to its power and flexibility in creating custom, interactive data representations. WebSockets enable real-time data streaming, crucial for up-to-the-minute solar flare information.

The modular file structure separates concerns and promotes maintainability. Docker containerization ensures consistency across development and production environments, while the AWS deployment strategy provides scalability and reliability for a global user base.

The focus on user customization (alerts, dashboard) and educational content aims to cater to both expert users and newcomers to solar flare monitoring, broadening the app's appeal and utility.
