D7.1.2 Towards a globally scalable archive federation technology (update)

This document presents the work done in the second year of the Assessing Scalability task of the Addressing Scalability and Preservation task of EUDAT. This document is an update to deliverable D7.1.1 looking at alternative components which could be used either within the current, or as part of an alternative, CDI. Based on the experience of projects discussed in the original deliverable, we propose an alternative scalable architecture and provide a migration path from the current CDI to this new system.
