What is cloud computing and why is it

important for Adult Literacy?

“Cloud computing is a nebulous term” (Anon.)

AlphaPlus

“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).

Why the Cloud for Distance Education?

Lori Herod

AlphaPlus

Distance Education Problems

faces endemic regionalization

programming challenges not computing

politics

funding

community leadership

professional collaboration

AlphaPlus

Cloud Computing

accessing and using ICT

housed on “server farms” - large industrial scale computing centres.

computing services at less cost

lower energy costs - data centres near power

Why cloud computing?

Katz, Goldstein & Yanosky (2009) :

Driving down capital costs of IT

Facilitating transparent matching of IT demand, costs, and funding;

scaling IT;

fostering further IT standardization;

accelerating time to market by reducing IT supply bottlenecks;

AlphaPlus

Why cloud computing (2)?

Katz, Goldstein & Yanosky (2009)

Countering consumerization of IT services

Access to scarce IT talent 

Supporting a five-9s & 24 x 7 x 365

Renewable energy

Interoperability internal/external

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

Cloud services

Distance Education:Approaches/Organizations

community groups

community colleges or partnerships of both

. Funding: federal employment & provincial education

Funding is usually short term

Difficult to sustain programs and staff

AlphaPlus

Target audiences for adult literacy

Rural and remote Canadians

Aboriginals

School dropouts (working poor)

New Canadians – immigrants who are literate in their own language.

Access to IT

AlphaPlus

What is the current use of IT to support

Distance Education?

Basic patterns:

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

AlphaPlus

Problems with uptake of the Cloud

No strong following among providers

Technology as a “moving target”

Accessibility

Few studies on efficacy

Trainers use technology personally but not for teaching

BUT accessibility in a cloud encourages localization and sharing across the wider community

AlphaPlus

Problems with uptake of the Cloud

Strangulation by big companies

•Predatory pricing

•UBB (Usage Based Billing)

•Throttling

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

AlphaPlus

The Cloud for DE

1. Provision of personal computing

2. Shared Community Resources

 3. Persistent personal storage - augmenting cognition

4. Analytics and personalization

5. Policy issues

6. Beyond text - Is literacy obsolete?

AlphaPlus

 Conclusion – Impact of Cloud Computing on DE

1. Utility

use of free services

Elastic: power on demand

OER

Web services: text to speech; translation etc.

Mobile learning

21st learning is not possible without the

skills for accessing and using the Internet
