This presentation aims to share the strategies and solutions adopted at 4Science to provide a reliable, high-performance hosting service for DSpace repositories. In the cloud era, repository platforms must support the adoption of cloud-native paradigms to deliver reliable, performant, and cost-effective services. In 2025, 4Science transitioned its hosting infrastructure from a traditional VM-based architecture to a modern, containerized deployment powered by Kubernetes and AWS cloud-native services. This transition has required changes and fine-tuning to the DSpace application codebase, a review of the development life cycle, and the adoption of new operational tools. We will explain the reasons behind the changes and the benefits obtained. Based on the operational data, we have identified several areas of improvements across the different application layers, from the frontend to the backend. Lack of support for horizontal scalability has been addressed to provide HA and consistent performance under heavy load. Many improvements have already been contributed to the DSpace codebase directly or via the ongoing merger of DSpace-CRIS; others will be discussed with the community and offered for inclusion in future versions. This approach keeps DSpace service sustainable, stopping institutions from over-provisioning of costly resources and therefore reducing the environmental impact.
