Deployment Strategy

1. Use containerization (Docker) for consistent environments
2. Deploy backend to cloud provider (e.g., AWS ECS or Google Cloud Run)
3. Host frontend on CDN for fast global access (e.g., Cloudflare or AWS CloudFront)
4. Utilize managed database service (e.g., AWS RDS for PostgreSQL)
5. Implement CI/CD pipeline using GitHub Actions or GitLab CI
6. Set up auto-scaling for backend services to handle load spikes
7. Use infrastructure-as-code (e.g., Terraform) for reproducible deployments
8. Implement comprehensive monitoring with ELK stack or cloud-native solutions
9. Regular backups and disaster recovery planning
10. Staged rollout strategy: development, staging, and production environments

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, crucial for a complex dashboard. Node.js on the backend provides fast, non-blocking I/O, ideal for real-time data processing. PostgreSQL offers robust relational data storage with good support for complex queries needed in vulnerability assessment.

The use of WebSockets enables real-time updates without constant polling, reducing server load and improving user experience. D3.js was selected for visualizations due to its flexibility and power in creating custom, interactive charts.

The modular file structure separates concerns and promotes maintainability. The deployment strategy leverages cloud services for scalability and reliability, with containerization ensuring consistency across environments. The focus on security practices and compliance is critical for a vulnerability assessment tool, building trust with users handling sensitive data.
