2. What is cloud computing and why is it important for Adult Literacy?
- Cloud computing is a nebulous term
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) .

- faces endemic regionalization
- programming challenges not computing
- professional collaboration
10. Cloud Computing
- housed on server farms -large industrial scale computing centres.
- computing services at less cost
- lower energy costs - data centres near power
11. Cloud Computing
12. Cloud Computing
- Reduces capital/energy costs
- Reduces physical space, labour
13. Concerns over cloud computing
14. Why cloud computing?
- Katz, Goldstein & Yanosky (2009) :
- Driving down capital costs of IT
- Facilitating transparent matching of IT demand, costs, and funding;
- 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 365
- 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
- compatibility of administrative systems
- on-going IT management infrastructures, tools, broadband availability, support services (helpdesk)
19. Cloud services 20. Private Cloud Services 21. Distance Education: Approaches/Organizations
- community 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
- School dropouts (working poor)
- New Canadians immigrants who are literate in their own language.
23. Needy populations
24. What is the current use of IT to support Distance Education?
- CBTs on DVD or via web-sites.
- Online course or workshops
- Web searches, email, conferencing,
- Writing, blogging & digital media
- assistive technologies, e.g. e-text readers
25. Problems with uptake of the Cloud
- No strong following among providers
- Technology as a moving target
- Trainers 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 Cloud
- Strangulation by big companies
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 cognition
- 4. Analytics and personalization
- 6. Beyond text - Is literacy obsolete?
29. Conclusion Impact of Cloud Computing on DE
- Web services: text to speech; translation etc.
