Unity Fleet MVP Technical Architecture

This document outlines the technical architecture for the Unity Fleet MVP components, defining the technology stack, data models, integration points, and deployment strategy.

Overall Architecture

The Unity Fleet MVP suite will follow a modern web application architecture with these key characteristics:

• Frontend: React-based single-page applications (SPAs) for all user interfaces
• Backend: Simulated API endpoints with mock data (no actual backend server required for MVP)
• Data Storage: Local browser storage (localStorage/IndexedDB) for persistence during demonstrations
• Deployment: Static site hosting for all components
• Integration: Common data models and shared components across all MVPs

Integration Strategy

Shared Components

The following components will be shared across multiple MVPs:

• Navigation Bar: Consistent navigation across all applications
• User Authentication: Simulated login/logout functionality
• Vehicle Cards: Standardized vehicle display components
• Charging Station Cards: Unified station status display
• Data Visualizations: Common chart and graph components
• Map Components: Reusable mapping elements
• Notification System: Consistent alert and notification UI

Data Sharing

Data will be shared between components using:

1. Local Storage: For persistent data across browser sessions
2. URL Parameters: For deep linking between applications
3. Shared State Library: Common Redux store for demonstration purposes

Deployment Architecture

The MVPs will be deployed as static web applications:

│                    Landing Page Portal                      │
└─────────────────────────────────────────────────────────────┘

• Each MVP will be deployed as a standalone application
• A central landing page will provide navigation to all components
• All applications will be responsive and work on desktop and mobile devices
• No backend server is required as all data will be simulated

Development Workflow

1. Setup: Create project scaffolding with shared components and styles
2. Component Development: Build individual MVPs in parallel
3. Integration: Connect components through shared data models
4. Testing: Verify functionality and user experience
5. Deployment: Deploy to static hosting
6. Documentation: Create user guides and demonstration scripts

Technical Considerations

Performance Optimization

• Use code splitting to reduce initial load times
• Optimize images and assets for web delivery
• Implement lazy loading for non-critical components
• Use efficient data structures for simulations

Browser Compatibility

• Target modern browsers (Chrome, Firefox, Safari, Edge)
• Use progressive enhancement for advanced features
• Test on multiple devices and screen sizes
• Ensure accessibility compliance

Simulation Fidelity

• Balance realism with performance
• Use realistic but simplified models for energy and financial simulations
• Ensure data consistency across all components
• Provide controls to adjust simulation parameters

This technical architecture provides the foundation for developing the Unity Fleet MVP components, ensuring a cohesive and impressive demonstration of the key concepts while maintaining technical feasibility within the project constraints.
