EPrints capabilities in the Cloud; a presentation at the EduServ "Repositories and the Cloud" event. For more info see http://repcloud.eventbrite.com/

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 Support Researchers’ environment supported by repository Research data managed by repository Research community assisted by repository

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

5. Bio-Diversity

6. Current EPrints Cloud Capabilities Amazon 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 Enabled Persistent Database & Storage Really Excited - Super Fast / Cheap / Easy!

7. Cloud to Desktop Storage Data can be stored on multiple storage services Local disk, SAN, NAS, Honeycomb, Cloud Researchers can mount repository objects as a networked filesystem Service usage and preservation risks can be monitored and analysed.

8. Hybrid Storage In EPrints A single storage solution has drawbacks. Cost vs. Speed vs. Reliability Repositories need to be agile: to utilize and be able to migrate to new platforms Leverage the benefits of each solution without losing control of your digital objects.

9. Local Disk Storage No local bandwidth costs Hard to expand Locally Managed High overheads cost Requires space and cooling Tied closely to the software Storage ecosystem

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

11. Cloud Storage Scalable Externally controlled Known Costings Unclear retention policy Re-Useable (using simple APIs) Global Scale Storage ecosystem

12. But Clouds Blow Away Recently: Yahoo Briefcase XDrive AOL Pictures HP Upline Sony Image Station Source: Tom Spring - PCWorld

13. Why use Hybrid Storage Use the best features of each storage type Performance Scaling-up bandwidth Optimisation Large-file handling Multimedia streaming Localised Delivery Local delivery from the cloud

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.

18. Controller Ruleset <choose> <when test="datasetid = 'document'"> <choose> <when test="$parent{relation_type} = 'isVolatileVersionOf'"> <plugin name="Local"/> </when> <otherwise> <plugin name="AmazonS3"/> </otherwise> </choose> </when> <otherwise> <plugin name="Local"/> </otherwise> </choose>

22. Preservation Services Object Classification Risk Analysis Mitigation and Migration

23. EPrintsForthcoming Development

24. EPrints Cloud Services Web based repository setup Much like getting started with a blog. Fill in a form and obtain a repository. Coming to EPrints core in next major release. Enterprise Support for Cloud Solutions Full Setup & Configuration Global Distribution Auto Upgrade & Patching Trusted Backup

25. EPrints 3.2 Plug-ins / Modules Everything builds on the core layer Major part of v3.2 is strengthening the core and adding more abstraction layers Improved data model Enhanced data facilities Enhanced metadata facilities Improved programming & API

26. EPrints 3.2 Structure

27. Community Driven Development There are many abstraction layers. Display Manipulation Upload Handlers Custom Datasets Import / Export Plug-ins Transcoding Plug-ins Database Plug-ins Storage Plug-ins One API

28. Storage Plug-ins Local NFS Amazon S3 Sun Cloud Storage Service Microsoft Azure Any others based on the S3 API…. (the last 3 all are) 5 Call API (about 30mins to write a plug-in)

29. Our Development Vision Empower the Community with a simple API API in 3.2 Give the community a platform to test their code Use the Cloud! Give the community a distribution mechanism The EPrints Bazaar (beta)

30. EPrints Bazaar Similar in concept to Apple’s App Store Every install of EPrints will have access to the Bazaar Single click install/uninstall of plug-ins EPrints Services Approved Plug-ins Enterprise support for limited 3rd party plug-ins

31. Summary EPrints provides the professional, enterprise level application for resource management Including cloud support at many levels Repository-in-the-cloud Storage-in-the-cloud Services-in-the-cloud
