wide range of disciplines. In addition, several universities offer online student
support services, such as online advising and registration, e-counseling, online
textbook purchase, student governments, and student newspapers.
Educational Usage of Cloud Computing
The recent trend in the E-Learning sector is screencasting. There are many
screencasting tools available but the latest buzz is all about the web-based
screencasting tools which allow the users to create screencasts directly from their
browser and make the video available online so that the viewers can stream the
video directly. The advantage of such tools is that it gives the presenter the ability to
show his ideas and flow of thoughts rather than simply explain them, which may be
more confusing when delivered via simple text instructions. With the combination
of video and audio, the expert can mimic the one on one experience of the class-
room and deliver clear, complete instructions. From the learner's point of view this
provides the ability to pause and rewind and gives the learner the advantage of
moving at their own pace, something a classroom cannot always offer.
Cloud computing is a new business model wrapped around new technologies
like virtualization, SaaS, and broadband internet. The cloud delivers computing
and storage resources to its users/customers. It works as a service on demand
policy. Recent interests offered new applications and elastic scalability with higher
computing parameters. So that, these positive effects have shifted to outsourcing of
not only equipment setup, but also the ongoing IT administration of the resources
as well. The results of a survey that have been completed in 2009 by Gartner
analysts (Fig. 1 ) about the IT trends (especially cloud computing) show that it is
being used more in the areas of finance and business when compared to other
sectors [ 3 ]. Results are shown as a pie chart and the labels on each different slice
represent different industrial sectors and services. The ''/'' is used to separate
different sectors with the same percentage.
