What is cloud computing and why is it important for Adult Literacy? Cloud computing is a nebulous term (Anon.) 3. CLOUD defined Eric Schmidt, CEO of Google, 2006:It starts with the premise that the data services and architecture should be on servers. We call it cloud computing they should be in a cloud somewhere. The National Institute of Standards and Technology (NIST) defines the term as follows:Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction(Mell & Grance, 2009) . 4. CLOUD defined 5. Gartner Hype Cycle 2010 6. AU o 7. Canadian Provinces 8. Why the Cloud for Distance Education? Lori Herod 9. Distance Education Problems faces endemic regionalization programming challenges not computingpolitics fundingcommunity leadership professional collaboration 10. Cloud Computing accessing and using ICThoused on server farms -large industrial scale computing centres. computing services at less cost lower energy costs - data centres near power 11. Cloud Computing Virtualization Device independence Elasticity 12. Cloud Computing On demand Pay for bandwidth used Industrial scale Reduces capital/energy costsReduces physical space, labour 13. Concerns over cloud computing Security Fast reliable internet switching costs hype 14. Why cloud computing? Katz, Goldstein & Yanosky (2009) : Driving down capital costs of ITFacilitating transparent matching of IT demand, costs, and funding; scaling IT; fostering further IT standardization; accelerating time to market by reducing IT supply bottlenecks; 15. Why cloud computing (2)? Counteringconsumerization of IT services Access to scarce IT talent Supporting a five-9s & 24 x 7 x 365Renewable energy Interoperability internal/external Katz, Goldstein & Yanosky (2009) 16. 17. Cloud service models 3 technical/marketing categories:Infrastructure as a Service(IaaS)where the expert user implements their own software to optimize use of the computing facility Platform as a Service(PaaS)where the client customizes their application to run inside the cloud management software Software as a Service(SaaS)like Gmail where the user simply uses the software provided suit user independence, expertise, budget and technical needs 18. Cloud services addressing content quality learner support compatibility of administrative systems on-going IT management infrastructures, tools, broadband availability, support services (helpdesk) evergreening of IT 19. Cloud services 20. Private Cloud Services 21. Distance Education: Approaches/Organizations community groupscommunity colleges or partnerships of both . Funding: federal employment & provincial education Funding is usually short term Difficult to sustain programs and staff 22. Target audiences foradult literacy Rural and remote Canadians AboriginalsSchool dropouts (working poor) New Canadians immigrants who are literate in their own language. 23. Needy populations Aboriginals working poorRural isolation UrbanAccess to IT 24. What is the current use of IT to support Distance Education? Basic patterns: CBTs on DVD or via web-sites. Online course or workshopsWeb searches, email, conferencing,Writing, blogging & digital media assistive technologies, e.g. e-text readers 25. Problems with uptake of the CloudNo strong following among providersTechnology as a moving target Accessibility Few studies on efficacyTrainers use technology personally but not for teaching BUT accessibility in a cloud encourages localization and sharing across the wider community 26. Problems with uptake of the CloudStrangulation by big companies Predatory pricing UBB(Usage Based Billing) Throttling 27. What might a cloud computing strategy for DE look like?What are the challenges to realize such a vision? THEN :email & collaboration software Now : variety of on-demand services that require tremendous processing power for short instances 28. The Cloud for DE 1 .Provision of personal computing 2. Shared Community Resources 3. Persistent personal storage - augmenting cognition4. Analytics and personalization5. Policy issues6. Beyond text - Is literacy obsolete? 29. Conclusion Impact of Cloud Computing on DE 1. Utility use of free servicesElastic: power on demand OER Web services: text to speech; translation etc. Mobile learning 21 stlearning is not possible without the skills for accessing and using the Internet
