GWDG mbH (Gesellschaft für wissenschaftliche Datenverbeitung mbH Göttingen) is a joint enterprise of the Göttingen University and the Max Planck Society. It is both the IT centre for the University and a computing and IT competence centre for the Max Planck Society. As such, GWDG provides a broad selection of services for scientists, projects, and institutes. Founded in 1970, it employs more than 110 staff members: scientists, IT-specialists, and technicians.The GWDG runs many services for different scientific communities including HPC clusters, compute and storage cloud facilities, data services including large-scale storage, archiving, and long‐term research data maintenance. Serving as a competence centre, the GWDG advises and supports institutes in facing challenges concerning scientific data processing. Furthermore, the GWDG pursues scientific research for eScience infrastructures, which includes topics in parallel computing, grids, clouds, Internet of Services, and large-scale, and long‐term data management. The main focus is on enabling the transition of new technologies into useful services for scientists. This includes also the support of collaboration and federation between computing and data infrastructures. In MIKELANGELO the GWDG is responsible for the integration of cloud infrastructure, the big data use case, the evaluation of the implementation and of the architecture, and dissemination of the project’s results.
