Deployment Strategy

1. Choose a cloud provider (e.g., Vercel for Next.js frontend, Heroku for Node.js backend)
2. Set up a managed PostgreSQL database (e.g., Heroku Postgres)
3. Configure environment variables for sensitive information
4. Implement CI/CD pipeline using GitHub Actions
5. Set up monitoring and logging (e.g., Sentry, Loggly)
6. Configure automatic backups for the database
7. Implement SSL/TLS for secure connections
8. Set up a CDN for static assets and images
9. Conduct load testing and optimize performance
10. Establish a rollback strategy for deployments

Design Rationale

• Next.js: Chosen for its server-side rendering capabilities, which improve SEO and initial load times for the ecommerce platform.
• Real-time updates: WebSockets or Server-Sent Events are used to provide instant feedback visualization, enhancing user engagement and data freshness.
• PostgreSQL: Selected for its robustness in handling relational data, which is crucial for managing complex relationships between users, products, orders, and reviews.
• Stripe API: Integrated for secure and reliable payment processing, essential for any ecommerce application.
• D3.js/Chart.js: These libraries offer powerful data visualization capabilities, allowing for the creation of interactive and informative feedback visualizations.
• Tailwind CSS: Utilized for its utility-first approach, enabling rapid UI development and easy customization.
• JWT Authentication: Implemented for secure, stateless authentication, which is scalable and works well with the chosen tech stack.

This design focuses on creating a modern, scalable, and user-friendly ecommerce platform with a unique real-time feedback visualization feature, setting it apart from traditional online stores.
