IoTsystemer

IoTsystemer is a framework for designing, deploying, and operating Internet of Things systems. It defines a modular software stack and reference architecture intended to support diverse devices, networks, and applications while promoting interoperability and scalable data processing. The term can refer to both the architectural approach and a set of tools and services that implement it.

The reference architecture of IoTsystemer typically comprises five layers: device, edge, transport, cloud, and application. The device layer includes sensors and actuators with standardized interfaces. The edge layer can perform real-time processing and local decision making to reduce latency and maintain operation during connectivity interruptions. The transport layer covers communication protocols such as MQTT, CoAP, and HTTP. The cloud layer provides data storage, analytics, orchestration, and centralized policy enforcement. The application layer exposes domain-specific services and user interfaces. A central orchestration service coordinates device management, configuration, and security policies, while standardized data models enable cross-domain interoperability.

Core features often include device discovery and onboarding, authentication and authorization, firmware and configuration management, lifecycle management, policy-based access control, data governance, streaming analytics, event processing, a rules engine, dashboards, and comprehensive APIs. Security considerations emphasize a defense-in-depth approach with encryption, secure boot, OTA updates, and zero-trust principles to minimize the attack surface and protect data integrity and privacy.

IoTsystemer stresses compatibility with existing open standards and formats, aiming to align with protocols such as MQTT, CoAP, LwM2M, and OPC UA, along with common data models. It is applied in domains such as industrial automation, smart cities, agriculture, logistics, and healthcare, where scalable, interoperable IoT solutions are needed.
