Abstract

The nature of the Internet was constantly changing from a place used to read web pages to an environment that allows end-users to run software applications. The need for education is increasing constantly and the development and the improvement of the e-learning solutions is necessary. Also, the e-learning systems need to keep the pace with the technology, so the new direction is to use cloud computing. Cloud computing is highly scalable and creates virtualized resources that can be made available to users. Cloud computing will have a significant impact on the educational environment in the future. Cloud computing is an excellent alternative for educational institutions which are especially under budget shortage in order to operate their information systems effectively without spending any more capital for the computers and network devices. Academic institutions take advantage of available cloud-based applications offered by service providers and enable their own students to perform...

Design of Cloud-based E-learning System for Virtual Classroom
WARSE The World Academy of Research in Science and Engineering

Cloud computing provides a great collection of computing resources that can be rapidly and elastically provisioned and released based on users' demand to serve a wide and regularly expanding variety of information processing requirements. Due to its tremendous advantages this technology is maturing quickly and is being adopted in many applications including government, business, and education. This research employs the Cloud as a learning environment for teaching Computer Science and related courses by removing the locality constraints, while simultaneously improving students' understanding of the material provided through practical experience with the finer details and subjects' complexities. Most of the universities infrastructures are underutilized and in some cases over utilization of resources occurs, in order to balance the usage of the resources there is need for an elastic technology. In order to develop an e-Learning platform for virtual or open distance learning (ODL) undergraduate students of computer science new methodologies (like cloud based e-Learning) should be taken into consideration for project, problem based learning and virtual computorium. The research identified several potential Computer Science courses which could be launched and taught through Clouds. This framework addresses the services of cloud computing in a new dimension and each layer (in virtual classroom cloud-based system) specifies the essential components (that is matching of computer science courses with cloud layers) needed to construct an academic cloud in an open distance learning environment. And finally, a way of implementing the framework is proposed.

A Study on E-Learning using Cloud Computing
IJRASET Publication

International Journal for Research in Applied Science & Engineering Technology, 2020

E-Learning is an efficiently growing tool used for learning. Although with great power comes greater responsibilities because storing the amount of data of a particular subject will require tons and tons of storage. Even if one manages to store the data of few subjects, it would be difficult to carry it to every student. Also, E-Learning is becoming vast each coming day which includes data of many books, blogs, notes, surveys both in video as well as audio format. Storing all this huge informative data is no doubt an extremely tedious task. Moreover, portability of such huge data structure can be exceedingly dicey. To overcome this complication Cloud Computing can majorly help. Cloud helps one keep less focus on the storage and the cynosure will be the content. The reason for this research is to exaggerate the practise of cloud computing with respect to E-Learning with different aspects. In addition to E-Learning there are various vendors who provide their clouds as a service to store, retrieve and implement the particulars whenever and wherever needed. In this paper we will bring forward various clouds used for E-Learning and also their measure of effectiveness. Different Clouds are bound to have different boundaries and limitations like public or private. This will prove as a note to improve various limitations including different clouds. We will be putting light on Virtual Labs, AWS Cloud, Moodle, hypervisors and many more. This paper will be an exploration on Virtual Labs and how interestingly important it is for E-Learning with different aspects like expansion of cloud dynamically, shrinking if not in use, parallel execution, multiple users accessing same cloud.

2013

E-learning is the use of computer, electronic device, mobile and communication devices in some way to provide training, just-in-time-information, guidance from experts, and educational or learning material among learners. E-learning facilitates and enables learners to learn anytime and anywhere. E-learning systems usually require many hardware and software resources to electronically transfer skills and knowledge. Many education institutions do not have the resources and infrastructure needed to run top e-learning solutions and cloud computing is the best solution. Cloud computing is growing rapidly in almost every sector including education and learning process with its promising infrastructure, platform and applications. In this paper the author studied and analyzed the challenges and scopes of cloud computing environment that will be helpful to build a reliable, cost effective and scalable education system, namely e-learning as a service. In this paper the author has proposed a fundamental and unified cloud computing model which is obliging both for vendors, clients, users, professionals, academicians, and researchers involved in development and enlargement of cloud computing services and solutions in education system.

Cloud-Based E-Learning : A Proposed Model and Benefits by Using E-Learning Based on Cloud Computing for Educational Institution
Nungki Selviandro

The increasing research in the areas of information technology have a positive impact in the world of education. The implementation of e-learning is one of contribution from information technology to the world of education. The implementation of e-learning has been implemented by several educational institutions in Indonesia. E-Learning provides many benefits such as flexibility, diversity, measurement, and so on. The current e-learning applications required large investments in infrastructure systems regardless of commercial or open source e-learning application. If the institution tended to use open source e-learning application it would need more cost to hire professional staff to maintain and upgrade the e-learning application. It can be challenging to implement e-learning in educational institutions. Another problem that can arise in the use of e-learning trend today is more likely to institution building their own e-learning system itself. If two or more institutions are willing to build and use an e-learning so they can minimise the expenditure to develop the system and share learning materials more likely happened. This paper dis- cuss the current state and challenges in e-learning and then explained the basic concept and previous proposed architectures of cloud computing. In this paper authors also proposed a model of cloud-based e-learning that consists of five layer, namely : (1) infrastructure layer; (2) platform layer; (3) application layer; (4) access layer; and (5) user layer. In addition to this paper we also illustrated the shift paradigm from conventional e-learning to cloud-based e- learning and described the expected benefits by using cloud-based e-learning.
