The article discusses the implementation of cloud computing in the German healthcare system, focusing on the integration of cloud technology into everyday clinical practice at a German university hospital. The authors highlight the challenges and opportunities presented by the transition from analog medicine to modern solutions like cloud computing, particularly in the context of European data protection laws. They describe a model approach that addresses legal and ethical concerns, emphasizing the importance of data protection and patient confidentiality. The article also outlines the technical aspects of cloud computing, including its service models (IaaS, PaaS, SaaS) and the role of standards like FHIR in facilitating interoperability. The authors present the AIQNET project, a consortium that has successfully integrated cloud computing into the Charité – University Hospital Berlin's infrastructure, demonstrating the feasibility of this approach in a large, established hospital setting. The project aims to establish a decentralized, interoperable ecosystem for medical data, while ensuring compliance with legal and ethical requirements. The article concludes by discussing the benefits of cloud computing in advancing medical research, improving patient care, and enhancing the efficiency of healthcare systems.The article discusses the implementation of cloud computing in the German healthcare system, focusing on the integration of cloud technology into everyday clinical practice at a German university hospital.
