Microservice-Based Architecture for Digital Twin Implementation: Leveraging Testing Strategies and Design Patterns for Enhanced Testability

Résumé fourni par la source

Digital Twins are considered a key software system in diverse industries. They allow for replicating the behavior of complex physical systems, thereby enabling real-time monitoring and enhancing decision-making capabilities. The inherent complexity and evolving nature of digital twins pose significant challenges in maintaining their long-term reliability. Consequently, prioritizing the testability of digital twins is crucial to ensure their accuracy over time. Given the novelty of the field, there is a notable research gap in the literature on testing strategies and methods for digital twins. Additionally, most of the research works have adopted a monolithic architecture for the development of digital twins. The internal tight coupling in this architecture and the constant evolution of digital twins results in retesting and redeployment of the entire software after any change. This makes the monolithic architecture inefficient for addressing the testability of complex and dynamic digital twins. This research proposes a microservice-based architecture for digital twins that addresses testability challenges. Furthermore, leveraging testing strategies and design patterns in this architecture can potentially increase testability, modularity, and internal decoupling of digital twins.
