Hybrid Cloud (Azure + Edge)

IoT Gateway System

A hybrid cloud IoT platform with edge computing, sensor data processing, and real-time analytics. This model addresses unique IoT challenges like device identity, physical security, and operational technology (OT) protocols.

IoT Architecture

Data flows from physical sensors through edge gateways to the cloud. The edge layer provides local processing, buffering, and protocol translation.

Field Devices

Physical sensors and actuators. Often resource-constrained with limited security.

Edge Gateway

Local processing and protocol translation. OT/IT bridge.

Cloud Ingestion

Secure cloud entry. Handles device auth and routing.

Data Lake

Long-term storage and analytics. Historical telemetry.

IoT vs Traditional IT Security

IoT devices present unique challenges: they're physically accessible to attackers, have limited CPU/memory for security features, use legacy protocols without encryption (Modbus, BACnet), and may have 10+ year lifespans without updates.
