Deployment Strategy

1. Choose a cloud provider (e.g., AWS, Google Cloud, or Vercel for Next.js)
2. Set up a production database instance (e.g., Amazon RDS for PostgreSQL)
3. Configure environment variables for production
4. Set up a CI/CD pipeline using GitHub Actions or GitLab CI
5. Implement automated testing in the CI pipeline
6. Use Docker for containerization to ensure consistency across environments
7. Set up load balancing and auto-scaling for the application servers
8. Implement CDN for static assets to improve global performance
9. Configure monitoring and logging (e.g., New Relic, ELK stack)
10. Establish a backup and disaster recovery plan
11. Implement SSL certificates for secure communications
12. Set up staging environment for pre-production testing

Design Rationale

The chosen tech stack (Next.js, Node.js, PostgreSQL) offers a balance of performance, scalability, and developer productivity. Next.js provides server-side rendering for improved SEO and initial load times, crucial for ecommerce. PostgreSQL offers robust relational data management needed for complex product and order relationships. The modular file structure promotes code organization and maintainability. The implementation plan prioritizes core functionalities first, allowing for iterative development and early testing. The deployment strategy focuses on scalability and reliability, essential for an ecommerce platform that may experience variable traffic loads.
