Deployment Strategy

Use containerization with Docker for consistent environments
Deploy backend to a scalable cloud platform (e.g., AWS ECS or Google Cloud Run)
Host frontend on a CDN for fast global access (e.g., Cloudflare or AWS CloudFront)
Implement a CI/CD pipeline using GitHub Actions for automated testing and deployment
Use a managed database service for reliability and easy scaling (e.g., AWS RDS)
Set up monitoring and logging (e.g., ELK stack or Datadog)
Implement automated backups and disaster recovery procedures
Use SSL/TLS encryption for all data in transit

Design Rationale

The application is designed with a focus on real-time data visualization and user engagement. React was chosen for its component-based architecture, allowing for efficient updates of the UI as new data comes in. D3.js provides powerful data visualization capabilities, essential for displaying complex pollinator population trends.

The backend uses Node.js for its event-driven architecture, well-suited for handling real-time data streams. PostgreSQL offers robust relational data storage, while Redis enhances real-time performance through caching.

The mobile-responsive design ensures that field researchers can easily contribute data from various devices. The modular file structure and use of modern development practices (like containerization) facilitate easier maintenance and scalability as the project grows.
