Cloud Computing &amp; Distance Education How cloud computing can sustain the promise of Distance Education Creative Commons Attribution 3.0 License Griff Richards, Rory McGreal, Brian Stewart EDEN June 2011 Dublin, Ireland</li></ul> <p> 2. What is cloud computing and why is it important for Adult Literacy? </p> <ul><li> Cloud computing is a nebulous term </li></ul> <ul><li>(Anon.) </li></ul> <p> 3. CLOUD defined </p> <ul><li>Eric Schmidt, CEO of Google, 2006:</li></ul> <ul><li>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. </li></ul> <ul><li>The National Institute of Standards and Technology (NIST) defines the term as follows:</li></ul> <ul><li>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 &amp; Grance, 2009) . </li></ul> <p> 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 </p> <ul><li>faces endemic regionalization </li></ul> <ul><li>programming challenges not computing</li></ul> <ul><li>politics </li></ul> <ul><li>funding</li></ul> <ul><li>community leadership </li></ul> <ul><li>professional collaboration </li></ul> <p> 10. Cloud Computing </p> <ul><li>accessing and using ICT</li></ul> <ul><li>housed on server farms -large industrial scale computing centres. </li></ul> <ul><li>computing services at less cost </li></ul> <ul><li>lower energy costs - data centres near power </li></ul> <p> 11. Cloud Computing </p> <ul><li>Virtualization </li></ul> <ul><li>Device independence </li></ul> <ul><li>Elasticity </li></ul> <p> 12. Cloud Computing </p> <ul><li>On demand </li></ul> <ul><li>Pay for bandwidth used </li></ul> <ul><li>Industrial scale </li></ul> <ul><li>Reduces capital/energy costs</li></ul> <ul><li>Reduces physical space, labour </li></ul> <p> 13. Concerns over cloud computing </p> <ul><li> Security </li></ul> <ul><li>Fast reliable internet </li></ul> <ul><li>switching costs </li></ul> <ul><li>hype</li></ul> <p> 14. Why cloud computing? </p> <ul><li>Katz, Goldstein &amp; Yanosky (2009) : </li></ul> <ul><li>Driving down capital costs of IT</li></ul> <ul><li>Facilitating transparent matching of IT demand, costs, and funding; </li></ul> <ul><li>scaling IT; </li></ul> <ul><li>fostering further IT standardization; </li></ul> <ul><li>accelerating time to market by reducing IT supply bottlenecks; </li></ul> <p> 15. Why cloud computing (2)? </p> <ul><li>Counteringconsumerization of IT services </li></ul> <ul><li>Access to scarce IT talent </li></ul> <ul><li>Supporting a five-9s &amp; 24 x 7 x 365</li></ul> <ul><li>Renewable energy </li></ul> <ul><li>Interoperability internal/external </li></ul> <p>Katz, Goldstein &amp; Yanosky (2009) 16. 17. Cloud service models </p> <ul><li>3 technical/marketing categories:</li></ul> <ul><li>Infrastructure as a Service(IaaS)where the expert user implements their own software to optimize use of the computing facility </li></ul> <ul><li>Platform as a Service(PaaS)where the client customizes their application to run inside the cloud management software </li></ul> <ul><li>Software as a Service(SaaS)like Gmail where the user simply uses the software provided </li></ul> <ul><li>suit user independence, expertise, budget and technical needs </li></ul> <p> 18. Cloud services </p> <ul><li>addressing content quality </li></ul> <ul><li>learner support </li></ul> <ul><li>compatibility of administrative systems </li></ul> <ul><li>on-going IT management infrastructures, tools, broadband availability, support services (helpdesk) </li></ul> <ul><li>evergreening of IT </li></ul> <p> 19. Cloud services 20. Private Cloud Services 21. Distance Education: Approaches/Organizations </p> <ul><li>community groups</li></ul> <ul><li>community colleges or partnerships of both </li></ul> <ul><li>. Funding: federal employment &amp; provincial education </li></ul> <ul><li>Funding is usually short term </li></ul> <ul><li>Difficult to sustain programs and staff </li></ul> <p> 22.

Needy populations </p> <ul><li>Aboriginals </li></ul> <ul><li>working poor</li></ul> <ul><li>Rural isolation </li></ul> <ul><li>Urban</li></ul> <ul><li>Access to IT </li></ul> <p> 24. What is the current use of IT to support Distance Education? </p> <ul><li>Basic patterns: </li></ul> <ul><li>CBTs on DVD or via web-sites.</li></ul> <ul><li> Online course or workshops</li></ul> <ul><li>Web searches, email, conferencing,</li></ul> <ul><li>Writing, blogging &amp; digital media </li></ul> <ul><li>assistive technologies, e.g. e-text readers </li></ul> <p> 25. Problems with uptake of the Cloud</p> <ul><li>No strong following among providers</li></ul> <ul><li>Technology as a moving target </li></ul> <ul><li>Accessibility </li></ul> <ul><li>Few studies on efficacy</li></ul> <ul><li>Trainers use technology personally but not for teaching </li></ul> <ul><li>BUT accessibility in a cloud encourages localization and sharing across the wider community</li></ul> <p> 26. Problems with uptake of the Cloud</p> <ul><li>Strangulation by big companies </li></ul> <ul><li>Predatory pricing </li></ul> <ul><li>UBB(Usage Based Billing) </li></ul> <ul><li>Throttling </li></ul> <p> 27.
