Introduction
Cloud computing has emerged as an important factor for fulfilling educational
computing needs. The term includes both the applications delivered as services
over the Internet and the hardware and systems software in the datacenters that
provide those services [

]. Another definition is given in (Cloud Computing,
retrieved [

]): Cloud computing uses the Internet and central remote servers to
maintain data and applications which is broken down into three segments:
''applications'', ''platforms'', and ''infrastructure''. The cloud is the term for
networked computers that distribute processing power, applications, and large
systems among many machines. The concept of cloud computing offers the
educational sector a way to increase IT capacity and add on the fly capabilities
without investing in new infrastructure, new training, or licensing new software.
There is no need to setup, configure, and manage large physical installations of
hardware and networks. This technology allows much more efficient computing by
centralizing storage, memory, processing, and bandwidth. It reduces/eliminates
problems associated with software version installation, control, and updates.
Approaches to E-Learning Services
E-learning services have evolved since computers were first used in education.
There is a trend to move toward blended learning services, where computer-based
activities are integrated with practical or classroom-based situations.
Computer-based learning:
Computer-based learning (CBL), sometimes abbreviated to CBL, refers to the
use of computers as a key component of the educational environment. While this
can refer to the use of computers in a classroom, the term more broadly refers to a
structured environment in which computers are used for teaching purposes.
Computer-based training:
Computer-based trainings (CBTs) are self-paced learning activities accessible
via a computer or handheld device. CBTs typically present content in a linear
fashion, much like reading an online book or manual. For this reason they are often
used to teach static processes, such as using software or completing mathematical
equations. CBTs provide learning stimulus beyond traditional learning method-
ology from textbook, manual, or classroom-based instruction. For example, CBTs
offer user-friendly solutions for satisfying continuing education requirements.
Instead of limiting students to attending courses or reading printed manuals,
students are able to acquire knowledge and skills through methods that are much
more conducive to individual learning preferences. For example, CBTs offer visual
learning benefits through animation or video, not typically offered by any other
means and certificate programs via the Internet at a wide range of levels and in a
