End-to-end-Architekturen zur Datenmonetarisierung im IIoT. Konzepte und Implementierungen
share
The value creation potential of the Internet of Things (IoT), that is the connection of arbitrary objects to the Internet, lies in the creation of business benefits through accessing and processing the circa 80 Zettabytes (1 ZB = 10^21 Bytes) of data produced by an estimated 40 billions of IoT endpoints (prognosis for 2025). This contribution derives and presents the information technology-related fundament and basis required to be able to reap this potential. Quantity and heterogeneity of the devices and machines especially encountered in the industry at large in the so-called industrial IoT (IIoT) require the use of a typically cloud-based IoT platform for logical concentration and more efficient management of the – unavoidable in industry – complexity. Stringent non-functional requirements especially regarding (low) latency, (high) bandwidth, access to large processing capacities, and security and privacy-related aspects necessitate the deployment of intermediary IoT gateways endowed with different capability sets in the edge continuum between IoT endpoints and the IoT platform in the cloud. This will be illustrated in the form of two use cases from corporate projects using a component architecture view point. Finally we argue that this classical concept of IoT projects needs to be strategically widened towards application integration (key word: IT/OT integration) and API management resulting in the coupling of a suitable integration and API management platforms to the IoT platform in order to use this end-to-end understanding of IoT/IIoT to fully leverage the innovation-stimulating and transformational character of IIoT and Industry 4.0.
