    Adapting Kubernetes to IIoT and Industry 4.0 protocols - An initial performance analysis
    (Softwaretechnik-Trends Band 43, Heft 1, 2023) Alamoush, Ahmad; Eichelberger, Holger
    Kubernetes (K8s) is one of the most frequently used container orchestration tools offering, as it offers a rich set of functions to manage containerized applications, it is customizable and extensible. Container virtualization of applications and their orchestration on heterogeneous resources including edge devices is a recent trend in Industrial Internet of Things (IIoT)/Industry 4.0, where K8s is also applied. However, IIoT/Industry 4.0 is a domain with high standardization requirements. Besides equipment standards, e.g., for electrical control cabinets, there are also demands to standardize network protocols, data formats or information models. Such standards can foster interoperability and reduce complexity or deployment/integration costs. Here, the proprietary communication protocol of K8s and similar orchestrators can be an obstacle for adoption. To explore this situation from an interoperability and integration perspective, we present in this paper an approach to replace the communication protocol of K8s without modifying its code base. We show by an experiment that applying our approach with three current forms of IIoT communication, namely Message Queuing Telemetry Transport (MQTT), Ad vanced Message Queuing Protocol (AMQP), and Asset Administration Shell (AAS), does not significantly affect the validity and the performance of K8s.

    Computational Economics als wirtschaftsinformatischer Beitrag zu einer interdisziplinären Netzwerktheorie
    (Wirtschaftsinformatik: Vol. 45, No. 5, 2003) Weitzel, Tim; König, Wolfgang
    Standards provide for compatibility and can therefore constitute networks. A possible contribution of the discipline of IS is transcending traditional economic network analysis by incorporating an interdisciplinary view on networks with economic utility maximization and an agent-based computational economics (ACE) approach. In doing so, the complex dynamics in networks occasioned by the existence of network effects and socially situated agents with bounded rationality can be modelled using computational laboratories. This provides an important step towards evaluating and develop alternative socioeconomic structures with regard to their effects on individual behavior and social welfare.

    Straight Through Processing auf XML-Basis im Wertpapiergeschäft
    (Wirtschaftsinformatik: Vol. 45, No. 4, 2003) Weitzel, Tim; König, Wolfgang; Martin, Sébastien V.
    Inefficient trading processes (trade, clearing, settlement) and globally increasing transaction volumes and speed require a thorough integration and automation of cross-border trade processes. A variety of mostly XML-based initiatives struggle to become the industry wide communications standard.In this paper, the status quo of XML usage within and between globally operating banks and the role, recognition, and relevance of initiatives aimed at developing an industry wide standard to enable a Straight Through Processing are analysed. FpML, FIX, SWIFT and ISO 15022 are considered the most important standards. Many banks see XML document size (transformation performance and bandwidth) as an obstacle to using XML but nevertheless unanimously agree on its role as future lingua franca. Overall, due to functional as well as strategic reasons elaborated in the paper, ISO 15022 is expected to become the dominant standard.
