D7.1.1 Towards a globally scalable archive federation

Primary tabs

Publication Date: 

This document presents the work done in the Assessing Scalability task of the Addressing Scalability and Preservation work package of EUDAT. This task looks at scalability and performance issues of the existing Collaborative Data Infrastructure, and compares this with other technologies which could be used within the current CDI based on perceived user community requirements in the three to five year timescale. We also compare EUDAT with other large data projects which are moving towards federated access and archival and assess if there are lessons to be learned from their experiences. In addition, we present work done on possible development of a scalable metadata infrastructure which could be adopted by EUDAT.
