Cloud Infrastructure

EsoCore provides a comprehensive cloud infrastructure solution consisting of two main components: a scalable Django REST API backend and a modern Nuxt.js frontend portal. This infrastructure is designed to be flexible, allowing deployment as a managed SaaS service by Newmatik or self-hosted by partners.

Architecture Overview

The EsoCore cloud infrastructure follows a microservices-like architecture with clear separation of concerns:

  • Backend API (Django): Handles all IoT device communication, data processing, and business logic
  • Frontend Portal (Nuxt.js): Provides the user interface for monitoring and management
  • Database: Stores device data, telemetry, user information, and system configuration
  • Real-time Communication: WebSocket support for live updates and alerts

Backend: Django REST API Server

Backend Core Features

The Django server serves as the central nervous system for the entire IoT ecosystem, providing:

  • Device Management: Complete lifecycle management of IoT devices with secure API key authentication
  • Telemetry Ingestion: High-performance time-series data collection from sensors and devices
  • Asset Monitoring: Equipment tracking, maintenance scheduling, and lifecycle management
  • Event Processing: Real-time system events, alerts, and automated responses
  • User Management: Role-based access control with customizable permissions
  • RESTful API: Comprehensive API with OpenAPI/Swagger documentation

Backend Technology Stack

  • Framework: Django 5.2 with Django REST Framework 3.16
  • Database: SQLite (development) / PostgreSQL (production)
  • Authentication: Dual-mode authentication supporting both API keys (devices) and session-based (users)
  • API Documentation: DRF Spectacular with interactive Swagger UI
  • Deployment Ready: Docker containerization with production-optimized settings

Backend Scalability Features

The Django backend is designed for horizontal and vertical scaling:

  • Database Optimization: Efficient query patterns and indexing for high-throughput telemetry data
  • Caching Layer: Redis integration for session management and frequently accessed data
  • Asynchronous Processing: Background task processing for heavy computations
  • Load Balancing Ready: Stateless design supporting multiple server instances
  • API Rate Limiting: Built-in throttling to prevent abuse and ensure fair resource usage

Key API Endpoints

Device-Facing Endpoints:

  • POST /api/iot/v1/auth/handshake - Device authentication
  • POST /api/iot/v1/telemetry/batch - Bulk telemetry data ingestion
  • GET /api/iot/v1/config - Device configuration retrieval
  • GET /api/iot/v1/ota/check - Over-the-air update availability
  • POST /api/iot/v1/ota/report - Update status reporting

Management Endpoints:

  • /api/devices/ - Device CRUD operations
  • /api/sites/ - Site management
  • /api/assets/ - Asset monitoring
  • /api/events/ - Event and alert management
  • /api/telemetry/ - Historical data access

Frontend: Nuxt.js Portal

Frontend Core Features

The Nuxt.js portal provides a modern, responsive web interface for end-users:

  • Real-time Dashboard: Live device monitoring with interactive telemetry visualization
  • Device Management: Complete device lifecycle management through web interface
  • Asset Tracking: Equipment monitoring and predictive maintenance scheduling
  • Alert Management: Real-time notifications and alert escalation
  • User Management: Role-based access control and user profile management
  • Mobile-First Design: Responsive interface optimized for all devices

Frontend Technology Stack

  • Framework: Nuxt.js 4.0 (Vue.js 3) with server-side rendering
  • UI Library: Nuxt UI with Tailwind CSS and Headless UI components
  • Charts & Visualization: Chart.js and ApexCharts for data visualization
  • State Management: Pinia for centralized state management
  • HTTP Client: Axios with automatic retry and error handling
  • Real-time Updates: WebSocket integration for live data streaming

Frontend Scalability Features

The Nuxt.js portal is built for performance and scale:

  • Server-Side Rendering: Improved SEO and initial page load performance

Integration and Communication

API Communication

The portal communicates with the Django backend through a well-defined REST API:

// Example API integration
const { data: devices } = await $api('/devices/')
const { data: telemetry } = await $api('/telemetry/', {
  params: { device_id, start_date, end_date },
})

Real-time Updates

WebSocket connections enable real-time data streaming:

// Real-time device status updates
const { connect, subscribe } = useWebSocket()
connect()
subscribe('devices', data => {
  // Update UI with live data
})

Authentication Flow

  • Device Authentication: API key-based with device-specific tokens
  • User Authentication: JWT tokens with refresh capability
  • Session Management: Secure cookie-based sessions for web interface

Security Considerations

Data Protection

  • End-to-end encryption for sensitive data
  • API key rotation and secure storage
  • Database encryption at rest
  • Secure communication protocols (HTTPS/WSS)
