What is Cloud Computing?

Definition

Cloud computing is a type of computing that providessimple, on-demand access to pools of highly elastic

computing resources

Or even more concise and clearly

Cloud computing is a style of computing where computingresources and are easy to obtain and access, simple to

use, cheap, and just work

Cloud Computing Characteristics

On demand self service

Broad network access

Resources pooling

Rapid elasticity

Measure service


7/33

Cloud Computing Services in

Academics Organizations

Used as personal workspace

Convenient tool to make teaching and learning interactive

Provide opportunity for ubiquitous computing

No need to backing up everything

No need to copy all stuff from one PC to another

Provide large amount of processing power


8/33

Definition

E-learning comprises all forms of electronically supported

learning and teaching. The information and communication

systems, whether networked learning or not, serve as

specific media to implement the learning process

What is E-learning?

Cloud provider is responsible for

Building and maintaining e-learning cloud

Providing technical support to e-learning cloud

Cloud users request to cloud provider for services to e-

learning cloud

E-learning cloud will provide the services accessed based

on users

Requirements of Programming

Education Cloud Services

Cloud computing services for providing programming

education includes C++ Workbook which has varioususer centric provision and administration functions

There are requirements for

Administrator

Framework and Architecture of

Programming Education Cloud Service

Services offered in Programming Education Environment

include

Logging of programming activities

Program Plagiarism detection

Programming workbook

Automatic programming marking To demonstrate the working mechanism of the

framework C++ Workbook is designed and developed as

a Software as a Service (SAAS)

The architectural components of the application have been

divided into three sections so that each section includes a

set of functions for three specific user roles i.e.Administrator, Instructor and Student

This is illustrated by Following Figure

Administrator Features

Responsible for managing accounts of students and

instructor

Creating classrooms

Allocating new instructor to existing classrooms

Updating question banks

Handling management of changes in application

Instructor Features

Lecturer who teaches programming subject through

the system is able to Create classroom

Assign his teaching assistant to be instructor for his class

Assign students to selected classroom

Create a problem set of exercise/quiz/exam

Select questions from the question bank for the problem

set

Supervise students assigned to him by giving advices in

terms of solving questions

Monitor studentsprogress

Student Features

A student who has been registered by the system

administrator has the right to

Request to join any classroom available

Complete exercise/quiz/exam that has been assigned

for the selected classroom Find the right answers and marks from the response to

the exercise/quiz/exam, since the system

automatically calculates marks

Conclusion and Future Work

Study presented discuss the challenges of e-learning

and the potential of cloud computing to improve

management of e-learning system We have proposed a framework for programming

education as a cloud service which combines the

elements from current practices of e-Workbook, e-

Learning and cloud computing technologies

The concept of e-learning environment through the use

of a new technique such as cloud computing

technology can be materialized in educational

institutions in various stages


31/33

Continue.

Academic institutions can benefit economically using cloud

computing environment because of minimal cost for

administration, and maintenance, high uptime and ease ofusage

Future work is adding remaining services
