Abstract
Modern IoT-based applications are developed by using microservices implementing various functionalities. However, they still tend to be rigid from a user’s perspective, i.e., the user typically adapts to how the software is designed. Conversely, we want the software and the IoT devices adapting to the user’s goal and its dynamic nature, thus making the user as one of the key design elements. For these reasons, in this talk I will present MiLA4U, a multi-level self-adaptive approach that works at the three different user, microservices, and devices levels. Specifically, it 1) makes use of a goal model defining run-time user goals that must be achieved without compromising the overall QoS, by adaptations towards the other levels. It therefore 2) continuously monitors the QoS of the microservices and IoT, and 3) leverages multiple algorithms for the QoS-aware dynamic selection, execution, and adaptation of microservices and IoT devices. MiLA4U is experimented on a real case study. Evaluation results show that it is able to satisfy the user goals while guaranteeing higher QoS on the microservices and IoT devices compared to standard baselines.
Speaker's Bio
Martina De Sanctis is Assistant Professor at the Computer Science department of the Gran Sasso Science Institute (GSSI), in L'Aquila, (Italy). Her research interests include behavioral and architectural adaptation of service- and IoT-based systems, collective aspects and modeling of multi-agent systems, dynamic adaptations, and its application to several domains, e.g., mobility, smart cities, IoT, and eHealth. She received a Ph.D. in Computer Science at the Doctoral School in Information and Communication Technology (2018), from the University of Trento and the Fondazione Bruno Kessler (FBK) in Trento. From 2013 to 2018 she was PhD fellow and researcher at FBK, at the Distributed Adaptive Systems research unit. She actively participated in European Projects in the large-scale collective systems (ICT-FET Proactive project) and digital industry (EIT Digital project) sectors. From 2019, she is actively involved in National Projects in the cultural heritage sector.
