System Architecture

Edge Devices

Diverse IoT sensors, actuators, and embedded systems that generate telemetry and respond to commands. Devices communicate using MQTT, CoAP, HTTP, WebSocket, and proprietary protocols, with support for custom adapters and protocol extensions.

Intelligent Gateways

Edge computing nodes that aggregate local device communications, perform protocol translation, execute local processing rules, and provide resilient buffering. Gateways maintain persistent connectivity to cloud services and handle offline scenarios gracefully.

Cloud Ingestion Layer

High-throughput entry point for device data in the cloud. Handles authentication, validates incoming messages, performs initial transformations, and routes data to appropriate downstream systems. Supports multiple transport protocols and connection patterns with auto-scaling capabilities.

Message Streaming

Distributed message queue and stream processing layer that buffers incoming data and provides durable storage. Enables decoupling between ingestion and processing, supporting backpressure handling, replay capabilities, and event sourcing patterns.

Data Persistence

Multi-tier storage architecture for time-series data, device state, configuration, and historical records. Supports both hot and cold storage tiers with configurable retention policies, compression, and efficient querying capabilities.

Processing Engine

Distributed compute layer that applies business logic, transformations, and rules to incoming data streams. Supports filtering, aggregation, enrichment, complex event processing, and machine learning inference. Enables real-time alerting and automated response generation.

Visualization & Alerts

User-facing interfaces for visualization, monitoring, and alerting. Dashboards display real-time and historical data with customizable widgets. Alerting systems notify users of threshold violations, anomalies, or system events through multiple channels.

Integration Hub

Comprehensive API layer and connectors for integrating with external systems, third-party services, and enterprise applications. Supports webhooks, REST APIs, GraphQL, and protocol adapters for common platforms with rate limiting and authentication.

Network Security

• TLS 1.3 encryption for all network communications
• Certificate-based mutual authentication for devices and gateways
• Automated key management with rotation and revocation
• DDoS protection and rate limiting at ingress points

Device Identity Management

• Unique device credentials and X.509 certificates
• Automated device registration and provisioning workflows
• Revocation mechanisms for compromised or decommissioned devices
• Device grouping and hierarchical access control

Access Control & Authorization

• Fine-grained, least-privilege access policies
• Role-based and attribute-based access control for users and services
• API authentication using OAuth 2.0 and JWT tokens
• Multi-factor authentication for administrative access

Observability & Compliance

• Comprehensive audit logs for all operations and data access
• Security event monitoring with real-time alerting
• Anomaly detection for unusual access patterns and behaviors
• Compliance reporting for GDPR, SOC 2, and industry standards
