What is cloud computing and why is it
important for Adult Literacy?
“Cloud computing is a nebulous term” (Anon.)

“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 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;

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

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
