Dr. Alexander Willner is the head of the Industrial Internet of Things (IIoT) Center  at the Fraunhofer Institute for Open Communication Systems (FOKUS)  and the head of the IIoT research group  at the chair of Next Generation Networks (AV)  at the Technical University Berlin (TUB). In joint collaboration with the Berlin Center of Digital Transformation (LZDV)  he is working with his groups in applying standard-based Internet of Things (IoT) technologies to industrial domains. With a focus on moving towards the realization of interoperable communication within the Industry 4.0, the most important research areas include industrial real-time networks (TSN), middleware systems (OPC UA), distributed AI (Digital Twins) and distributed Cloud Computing (Edge Computing) including management and orchestration.
Prior research positions include the University Bonn, he holds an M.Sc. and a Ph.D. (Dr.-Ing.) in computer science from the University Göttingen and the Technical University Berlin respectively. His research interests are on distributed information systems, linked data, communication middleware and service-oriented architectures. He is active in relevant standardization activities and alliances and gives a corresponding lecture at the Technical University Berlin; and in the past at the Humboldt University of Berlin as well.
At various occasions Dr. Willner also acts as ambassador for the science capital Berlin .

|Abstract||The remarkable success of cloud computing has change the way services and applications are implemented and offered not least because of the flexibility and scalability that such an environment can offer. Cloud federation has tremendous potential for the industry as an effective way to increase the capacity of resources and diversity of offerings while keeping costs relatively low. Yet cloud federation is still in its infancy, with different approaches being introduced, either in terms of architectural design or the availability of test facilities. This paper introduces the FIWARE approach for federating multiple cloud-based infrastructures targeting different fields related to Future Internet and Smart-Cities innovative de- velopments. Sustainability is considered in the focus of our approach. In addition to the traditional cloud services, the FIWARE federation mainly offers a set of general-purpose platform functions and services extended with further facili- ties (e.g. sensing and Software-Defined-Networking (SDN) capabilities) advancing the market with smart infrastructures. These services are available through open (public and royalty- free), vendor-independent APIs supporting open innovation. We present federated infrastructure sustainability considera- tions along with the FIWARE federation architecture design that is implemented and deployed within a federation of 17 cloud-based infrastructures distributed across Europe.|
