Deployment Strategy

1. Choose a cloud provider (e.g., AWS, Google Cloud, or DigitalOcean)
2. Set up a production environment with separate servers for the frontend, backend, and database
3. Use Docker containers for easy deployment and scaling
4. Implement a CI/CD pipeline using GitHub Actions or GitLab CI
5. Set up HTTPS using Let's Encrypt for secure connections
6. Use a content delivery network (CDN) for static assets
7. Implement database backups and disaster recovery procedures
8. Set up application performance monitoring (e.g., New Relic or Datadog)
9. Use log aggregation tools for easier debugging and monitoring
10. Implement auto-scaling policies to handle traffic spikes

Design Rationale

The chosen tech stack (React, Node.js, PostgreSQL) offers a balance of performance, scalability, and developer productivity. React provides a robust framework for building interactive UIs, while Node.js allows for efficient real-time data processing. PostgreSQL was selected for its reliability and support for complex queries needed for metrics analysis.

The microservices architecture allows for independent scaling of the monitoring service and the main application. Socket.io enables real-time updates without constant polling, improving performance and user experience.

The focus on data visualization and customizable alerts ensures that users can quickly identify and respond to issues, making the application highly valuable for maintaining website uptime and performance.
