4 4 “Cross-Industry Preservation Architectures” – PASIG May, 2011 Agenda ● LTDP Paradoxes (Laws designed to be broken) ● New Digital Preservation Models That the cloud empowers That the cloud empowers ● Using the Cloud for Digital Archives (Digital Preservation)

5 5 “Cross-Industry Preservation Architectures” – PASIG May, Paradoxes of Digital Preservation ● Data will be lost ● Migration does not scale ● Access & use models keep changing ● Cost overwhelms everything complexity does not

6 6 “Cross-Industry Preservation Architectures” – PASIG May, 2011 How do we break them? “Old” Laws of Digital Preservation

7 7 “Cross-Industry Preservation Architectures” – PASIG May, Year Complexity Barrier ● Overwhelming growth, cost, change Constant Physical and Logical migration Constant Physical and Logical migration Power, cooling, space, people, resources, maintenance,… Power, cooling, space, people, resources, maintenance,… Always adding & migrating systems, networking, storage Always adding & migrating systems, networking, storage Managing thousands of formats Managing thousands of formats Constant Auditing and recovery of damaged or lost data Constant Auditing and recovery of damaged or lost data Thousands of moving parts Thousands of moving parts Complex systems and architectures Complex systems and architectures Changing software platforms Changing software platforms

8 8 “Cross-Industry Preservation Architectures” – PASIG May, 2011 Aha! Move from “physical” preservation architectures and design as in physical media or a physical repository (a 2002 ‘OAIS’) to “virtualized” Preservation Services based on Service Management principles (Sounds like the Cloud…)

9 9 “Cross-Industry Preservation Architectures” – PASIG May, 2011 New Digital Preservation Models Using the Cloud

26 26 “Cross-Industry Preservation Architectures” – PASIG May, 2011 Summary Thoughts Preservation Architectures: Virtualization and Cloud

27 27 “Cross-Industry Preservation Architectures” – PASIG May, 2011 Move to Virtual Preservation ● Shift thinking from “Physical” Preservation to “Virtual” ● Virtualization Applies in many ways System, storage, application, infrastructure System, storage, application, infrastructure Information Information Migration – both physical and logical Migration – both physical and logical Cost reduction Cost reduction ● Conclusion: ‘Cloud’ has a positive role

28 28 “Cross-Industry Preservation Architectures” – PASIG May, 2011 Using the Cloud ● Start out Private, Move to Hybrid ● Apply Service Management Principles Classify, Requirements, SLAs, Design, Audit, Improve Classify, Requirements, SLAs, Design, Audit, Improve ● Design for the Cloud Create strong and measureable SLA style contracts Create strong and measureable SLA style contracts Test, Audit, Verify Test, Audit, Verify ● Use and Promote CDMI Need cloud interface, management, and information portability standards Need cloud interface, management, and information portability standards
