Edge Computing

A practical five-layer model for IoT systems, showing how devices, protocols, edge runtime, backend services, and applications fit together.

A diagram-first overview of a practical IoT system architecture, covering devices, edge hubs, messaging, APIs, backends, and user interfaces.

How the OttO IoT gateway uses MQTT to receive telemetry from device stations, parse topic-based sensor identifiers, pass readings through Go channels, and protect the gateway from unbounded in-memory growth.
