Eprints offers a comprehensive platform for managing and sharing research materials, emphasizing cloud-based storage solutions and hybrid storage capabilities. It supports diverse functionalities including administrative reporting, data sharing, and e-learning, while facilitating scalability and performance through various storage types like local and cloud options. The forthcoming Eprints 3.2 aims to enhance its core functionalities and community-driven development through a plugin system, promoting ease of use and integration with external services.

1. EPrintsCloud Visions

2. What is EPrints For?EPrints offers a safe, open and useful place to store, share and manage material in the pursuit of research and educational agendas.administrative reporting, collaboration, data sharing, digital profile enhancement , e-learning, e-publishing, e-research, marketing, open access, preservation, publicity, research assessment, research management, scholarly collections

3. Research Curation, Researcher SupportResearchers’ environment supported by repositoryResearch data managed by repositoryResearch community assisted by repository

4. What is a RepositorySafe, secure, persistent, managed storage for filesSafe, secure, persistent management of shareable FRBR worksSafe, secure, persistent, management of scholarly & scientific working Leading to…Science 2.0 / The Fourth Paradigm / Data Intensive ScienceThe challenge is not cloud computing but cloud thinking

5. Bio-Diversity

6. Current EPrints Cloud CapabilitiesAmazon Elastic Compute Machine Images (AMIs)Small (Single Core / 1.7Gb)Large (64 Bit / Quad Core / 7.5Gb)Extra Large (64 Bit / 8 Core / 15Gb) EPrints 3.2 is 64 Bit EnabledPersistent Database & StorageReally Excited - Super Fast / Cheap / Easy!

7. Cloud to Desktop StorageData can be stored on multiple storage servicesLocal disk, SAN, NAS, Honeycomb, CloudResearchers can mount repository objects as a networked filesystemService usage and preservation risks can be monitored and analysed.

8. Hybrid Storage In EPrintsA single storage solution has drawbacks.Cost vs. Speed vs. ReliabilityRepositories need to be agile: to utilize and be able to migrate to new platformsLeverage the benefits of each solution without losing control of your digital objects.

9. Local Disk StorageNo local bandwidth costsHard to expand Locally Managed High overheads cost Requires space and cooling Tied closely to the software Storage ecosystem

10. Local Archival StorageSpecialist Expensive to purchase Locally Managed Space and running costs Expandable Storage ecosystem

11. Cloud StorageScalable Externally controlled Known CostingsUnclear retention policy Re-Useable (using simple APIs) Global ScaleStorage ecosystem

14. EPrints Storage ControllerThe storage controller decides where to put a file.

15. Rule-based policy defined by XML configuration file

16. Large binary files of scientific data (raw machine result data) can be stored in a large disk (slower access) system and sent to a tape company for long term storage.

17. Processed results can be stored locally and in the cloud ready for rapid delivery to end points. Architecture Diagram
