1 Cloud Computing in Higher Education: Impact and Challenges Anju Gautam Research Scholar, Jagannath University, Jaipur Abstract: Cloud computing is a slogan at present days. It has altered the entire state of affairs. Cloud computing means on demand facility. Quite a lot of educational institutions have been bearing in mind and some of them even adopting cloud computing strategies in order to convene up their requirements. Cloud computing services are a growing need for business organizations as well as for educational institutions. Although there are still several risks and challenges are associated with cloud but its latent benefits overshadow the risks. This paper start defining cloud computing, key characteristics of cloud computing, it s deployment and service models, association between them. Further we portray the role, impact and challenges of cloud computing in the sector of higher education. Keywords: Cloud computing, cloud computing models, Characteristics of Cloud computing, Higher education CLOUD COMPUTING Cloud computing concept is an advancement of distributed computing, in which a program or application running over on numerous machine which is connected by a network. The Internet makes this method easy and achievable even for the general user also. National Institute of Standards and Technology, USA defines cloud computing as: a model for enabling ubiquitous, 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. Actually Cloud computing uses sharing concept like sharing of resources, information as well as services on demand with the help of Internet Cloud computing concept is already used widely in academics. Cloud - based services are used every day by novice and educationalist to support learning, societal communication, content creation, publishing and cooperation. Following are the Examples of cloud-based services are YouTube, Drop box and Google Apps. The different types of services provides by the cloud are: Mail: editor@globalresearch.co.in 17
2 1. Software as a Service (SaaS) :Presently used in education. Anywhere Anytime apps. In this type the data stored not only in the cloud but the application too, but for this the user requiring only a supportive browser. The most excellent well-known examples are Google Apps for Education and MicrosoftLive@edu which make available communication and office applications such as and spreadsheets. 2. Platform as a Service (PaaS): This is an operating environment in which various applications are running. With PaaS, one can build up new applications or services in the cloud that do not require a particular platform to run, and can make them extensively available to users through the Internet. PaaS provides cloud -based application development tools in addition to services for testing, deploying, collaborating on, hosting, and maintaining applications. Examples of PaaS include Microsoft's Azure Services Platform (Microsoft, 2012), Salesforce's Force development platform, Google Apps Engine, Amazon's Relational Database Services and Rackspace Cloud services etc. 3. Infrastructure as a Service (IaaS): This is on-demand data centers. At this juncture consumers can rent basic computing resources such as processors and storage, and use these resources to run their own operating systems and applications. Customers pay for only what they use, and the service provides all the capacity they need, but Customers are responsible for monitoring, managing, and patching their on-demand infrastructure. One big advantage of this service is that it offers a cloud - based data center without requiring you to install new equipment or to wait for the hardware procurement process. This means one can get IT resources at his institutions that otherwise might not be available. For example Amazon s Elastic Compute Cloud; organizations can use this infrastructure to run Linux servers on virtual machines and scale up usage as required. The cloud space is rapidly adopting a plethora of new acronyms and phrases to describe different aspects of the offering, which is the next evolution of the Internet. For purposes of this paper, the following National Institute of Standards and Technology (NIST) definitions are used for deployment models: Private cloud - The cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on premise or off premise. Community cloud - The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise. Mail: editor@globalresearch.co.in 18
3 Public cloud - The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. Hybrid cloud -The cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds). LITERATURE REVIEW Cloud computing predecessors have been around for some time now but the term became popular sometime in October 2007 when IBM and Google announced a collaboration in that domain This was followed by IBM s announcement of the Blue Cloud effort. Since then, everyone is talking about Cloud Computing. Of course, there also is the inevitable Wikipedia entry. It is conceivable that August 24, 2006 will go down as the birthday of Cloud Computing, as it was on this day that Amazon made the test version of its Elastic Computing Cloud (EC2) public [Business Week 2006]. This offer, providing flexible IT resources (computing capacity), marks a definitive milestone in dynamic business relations between IT users and providers. The term first became popular in 2007, to which the first entry in the English Wikipedia from March 3, 2007 attests, which, again significantly, contained a reference to utility computing. Today, Cloud Computing generates over 10.3 million matches on Google. The scope of Cloud Computing grew from simple infrastructure services such as storage and calculation resources to include applications. However, this meant that forerunners such as application service providing and Software as a Service would also henceforth be included under the designation of Cloud Computing PRESENT EDUCATION SYSTEM So many private and public educational institutions have become greatly reliant on information technology to service their requirements. These services are ever more provided using Internet technologies to educator and learner and accessed from web browsers. The services are accessible economically or liberally to education, often with much higher availability than can be provided by the educational institution. Are we therefore facing a prospect where the mass of educational services will be hosted in the cloud and organization no longer host their individual data centers with costly hardware, power bills, staff salaries and computing assets which are hardly ever fully utilized? This course of action brief has analyzed some of the rising benefits and challenges of cloud computing for the educational zone. The majority of the work is done by hand from classroom teaching to daily attendance system to examination scheme. Mail: editor@globalresearch.co.in 19
4 CLOUD TECHNOLOGY IN ACADEMIC INSITUTIONS Cloud computing technology can provide solutions for the above stated problems in educational institutions. Cloud computing facilitate users to manage and access data by the use of the Internet. The major user or client of a typical higher education cloud includes students, Faculty, administrative department, Examination cell and Admission cell as shown in Figure 1. Figure1: cloud services for education System The major stuff of the institution is linked to the cloud. Different login is given for all the users for their particular work. Educator can upload their Tutorials, assignments, and tests on the cloud server from where students will be able to see all the content provided by the educators via Internet using systems and some other electronic devices both at home and institutions and 24X7. The education system will make it possible for teachers to recognize problem areas related to students, in which they tend to make mistakes, by evaluate students study report. In doing so, it will also permit educator to improve teaching materials and processes. This will helps to the students to use online teaching materials during class as well as also be able to access these materials at residence, using them to prepare for lessons. Deployment of cloud computing systems will trim down the cost of operation because servers and learning materials are available in sharing mode with other institutions. Fig 1: Services attached to Education Cloud In the traditional deployment model, all Information Technology resources are housed and managed in -house. BENEFITS OF CLOUD COMPUTING FOR INSTITUTIONS AND STUDENTS Mail: editor@globalresearch.co.in 20
5 1. Personalized Learning: Cloud computing affords opportunities for greater student choice in learning. Using an Internet- connected device, students can access a wide array of resources and software tools that suit their learning styles and interests. 2. Reduced Costs: Cloud-based services can help institutes reduce costs and accelerate the use of new technologies to meet evolving educational needs. Students can use office applications free of cost without having to purchase, install and keep these applications up to date on their systems. It also provides the facility of Pay per use for some applications. 3. Accessibility: Availability of the services is the most significant and most wanted by the user. Use of the education cloud 24 X7 is the availability that is needed by this system without breakdown. Users can login and access the information from anywhere. 4. No need of additional Infrastructure: educational institutions and governments now days are free to focus on their objectives that is making more research facilities accessible to the students 5. Green environment: Use of Education cloud will trim down the carbon footprint. 6. User Friendly: This facility is user friendly, understanding, easy navigation and less complex. SECURITY ISSUES Security of data is a big issue in cloud computing. In cloud computing important data stored in one place and it will increase the chances of hacking. Protection of data is a major security issue. All Educational Institutions wants security of their crucial and most important data. If it is hosted within the institution. Transferring data to a third party for hosting in a remote data Centre, not under the control of the institution on and the location of which may not be known presents a risk. Some cloud service providers nowadays provide guarantees in their contracts that their personal data will only be stored in particular countries. It has been recommended that the provision of cloud services through a single provider is a single point of failure and that it would be better to contract more than one cloud provider in order to reduce risk. Another big security issue is Unsolicited advertising in which cloud providers will target users with unsolicited or advertising. Mail: editor@globalresearch.co.in 21
6 CONCLUSION The cloud allows to the intended user to access their work from any place from any time share related information with anybody. It frees the user from needing a specific machine to access a file or an application like a word processor or spreadsheet program. Rest in the present paper a cloud based education system is introduced and how it is beneficial for students, faculty and the educational institutes. It providing quality education to the institutions. REFERENCES 1.G.M.
