ABSTRACT: Teach­ing, learn­ing and train­ing process­es are intense­ly affect­ed by the chal­lenges of this epoch of dig­i­tal envi­ron­ment. They give prospects for the pro­fes­sion­als in their high­er and fur­ther edu­ca­tion for train­ing and devel­op­ing their prac­ti­cal skills as the today smart user must need in this fast- mov­ing and opu­lent­ly diverse field. The gain­ing pop­u­lar­i­ty of eru­di­tion on the inter­net, the edi­fice of per­fect cloud-based learn­ing envi­ron­ment has become one of the hottest points on research­ing remote edu­ca­tion. Now a day, cloud com­put­ing and Cloud based E learn­ing is ris­ing speed­i­ly and plays a vital and pow­er­ful role in the field of edu­ca­tion and learn­ing. It sup­ports the next gen­er­a­tion users to per­form their tasks remote­ly with pay­ing less cost by uti­liz­ing the cloud-based appli­ca­tions offered by the cloud ser­vice providers and also the same cloud based solu­tions they can con­fig­ure on basis of open source cloud solu­tions at free of cost. These tech­nolo­gies are aimed at run­ning appli­ca­tions such as word pro­cess­ing, spread­sheets, access data­base, remote com­put­ing, online com­pil­ers and debug­gers and online cours­es and many more pro­vid­ed by the inter­net ser­vice provider in the vir­tu­al envi­ron­ment while on the move by a flex­i­ble infra­struc­ture as all the data and infor­ma­tion is stored in the cloud ambiance. This paper focus­es on how Cloud based E learn­ing ben­e­fits the e‑learners by using cloud com­put­ing ser­vices and presents Cloud based E learn­ing approach­es by using cloud com­put­ing.

1.  INTRODUCTION

In recent years, the fast devel­op­ment of dig­i­tal tech­nolo­gies is cre­at­ing not only new oppor­tu­ni­ties for our dig­i­tal world but chal­lenges to it as well. Our dig­i­tal world is now being sharp­ened by rapid advances by tech­nolo­gies in the field of edu­ca­tion web based e learn­ing and, sci­ence tech­nol­o­gy and many more. Today, Cloud based E learn­ing and cloud com­put­ing is emerg­ing as the new par­a­digm of mod­ern edu­ca­tion with reduced upfront invest­ment for teach­ers and the appren­tices. Cloud based E learn­ing is an Inter­net based learn­ing process, using Inter­net tech­nol­o­gy to design, imple­ment, select, man­age, sup­port and extend learn­ing, which will not replace tra­di­tion­al edu­ca­tion­al meth­ods, but will great­ly improve the effi­cien­cy of high­er edu­ca­tion [1]. The E learn­er sys­tem moti­vates the e‑learner user in their learn­ing process any­time and any­where at his/her own pace while on the move with the help of elec­tron­ic gad­gets like smart phones, PDA, tablets etc. and with pow­er­ful strat­e­gy of cloud com­put­ing. The cloud

com­put­ing is a col­lec­tion observ­er deliv­er­ing resources that can be accessed remote­ly via the Inter­net in real-time. It is also a place for the users to cre­ate, store and access per­son­al infor­ma­tion by much Sev­er­al trends are open­ing up the era of Cloud Com­put­ing, which is an Inter­net based devel­op­ment and use of com­put­er tech­nol­o­gy. The ever cheap­er and more pow­er­ful proces­sors, togeth­er with the “soft­ware as a ser­vice” (SaaS) com­put­ing archi­tec­ture, are trans­form­ing data can­ters into pools of com­put­ing ser­vice on a huge scale. Mean­while, the increas­ing net­work band­width and reli­able yet flex­i­ble net­work con­nec­tions make it even pos­si­ble that clients can now sub­scribe high qual­i­ty ser­vices from data and soft­ware that reside sole­ly on remote data cen­ters. More effi­cient way of com­put­ing tech­nol­o­gy [2]. The devel­op­ment of these tech­nolo­gies is direct­ly relat­ed to the increas­ing access to the com­mu­ni­ca­tion tech­nol­o­gy, as well as its decreas­ing cost pro­vid­ed by the mobile ser­vice providers. The learn­ers choose to learn over dis­tance or in per­son at a tra­di­tion­al cam­pus; the pow­er of E learn­er and vir­tu­al col­lab­o­ra­tion is grow­ing fast in edu­ca­tion and in the world­wide econ­o­my. This pow­er is best real­ized with a well- planned cloud com­put­ing and E‑learner strat­e­gy. Learn­ers can use the enor­mous inter­ac­tiv­i­ty of inno­v­a­tive media and devel­op their skills, knowl­edge, and aware­ness of the future domain. The ben­e­fits of these com­put­ing can sup­port edu­ca­tion insti­tu­tions to resolve com­mon chal­lenges such as cost reduc­tion, rapid and effec­tive com­mu­ni­ca­tion, secu­ri­ty, pri­va­cy, flex­i­bil­i­ty and acces­si­bil­i­ty. The Edu­ca­tion­al insti­tutes, busi­ness­es and many oth­er indus­tries are adopt­ing the ser­vices of cloud com­put­ing because of the fol­low­ing rea­sons:

1. Cost Sav­ing: One of the most appeal­ing rea­sons to switch to the cloud is the cost sav­ings fea­ture. With the cloud, the user will pay for appli­ca­tions only when need­ed and many appli­ca­tions are includ­ed free of charge as an open source appli­ca­tions.
2. Scal­a­bil­i­ty: One of the major rea­sons for using cloud com­put­ing is its scal­a­bil­i­ty. Cloud com­put­ing allows

Uni­ver­si­ties, col­leges and IT indus­tries to eas­i­ly upscale or down­scale IT require­ments as and when required.

• User friend­ly: Quite sim­ply, cloud com­put­ing is easy to get up and run­ning. Instead of hav­ing to down­load

And/or install soft­ware your­self, in the cloud it is all done for you.

• Time Sav­ing: This allows for on-demand analy­sis of study mate­r­i­al instant­ly.
• Course­ware Resource and wiki pages: It includes web pages design and meth­ods for course­ware like video exam­ples of study mate­r­i­al, review of aca­d­e­m­ic papers, text book extend­ed resources and the use of wiki pages for teach­ing assis­tant and stu­dent inter­ac­tive shar­ing and col­lab­o­ra­tion.
• Fault Tol­er­ant: Cloud providers can afford to have mul­ti­ple data cen­ters and mul­ti­ple Inter­net con­nec­tions at each data cen­ter to adore fault tol­er­ance. As they offer lev­els of data pro­tec­tion forth e- learn­er user’s sim­ple night­ly back­ups, such as con­tin­u­ous data

pro­tec­tion, gen­er­a­tors to han­dle pow­er out­ages, and high-end servers that can keep run­ning even one com­po­nent fails. Apart from the above men­tioned rea­sons, the Learn­ers, Con­sumers and busi­ness­es uti­lize the cloud on a dai­ly basis even if they’re not aware of it. For instance, when we arous­ing e‑mail, or go to a social net­work and post pho­tos, access online doc­u­ment soft­ware, or use company’s hardware/software we prob­a­bly use the cloud ser­vices.

2.  CLOUD COMPUTING

An Out­sourc­ing Frame to the cloud the term cloud is relat­ed to inter­net. Cloud com­put­ing is an inter­net based com­put­ing where vir­tu­al shared servers deliv­er soft­ware, infra­struc­ture, plat­form, devices and addi­tion­al resources that are host­ing to clients with com­pa­ra­ble qual­i­ty of ser­vice on demand but at a much low­er cost. Essen­tial Char­ac­ter­is­tics that cloud com­put­ing should have:

• On-demand self-ser­vice.
• Broad net­work access.
• Vir­tu­al­iza­tion.
• Resource pool­ing.
• Secu­ri­ty and Main­te­nance.

3.  CLOUD BASED E LEARNING

A new Par­a­digm Out-of-class­room and in-class­room edu­ca­tion­al expe­ri­ences Cloud based E learn­ing is the com­put­er and with the aid of net­work enabled trans­fer of skills and knowl­edge. Cloud based E learn­ing appli­ca­tions and process­es offer Web-based learn­ing, com­put­er-based learn­ing, vir­tu­al edu­ca­tion prospects and dig­i­tal col­lab­o­ra­tion to their e‑users. Pop­u­lar Cloud based E learn­ing tech­nolo­gies include:

• Con­tent is deliv­ered via the Inter­net.
• Voice-cen­tered tech­nol­o­gy, such as Web­casts, Webi­na­rs
• Video tech­nol­o­gy, such as instruc­tion­al videos, DVDs, and inter­ac­tive video­con­fer­enc­ing.
• Com­put­er-cen­tered tech­nol­o­gy deliv­ered over the Inter­net Bare Met­al servers, Vir­tu­al servers.

4.  APPROACHES TO CLOUD BASED E LEARNING FACILITIES

Cloud based E learn­ing is broad­ly used nowa­days in dif­fer­ent edu­ca­tion­al stages i.e. con­tin­u­ous edu­ca­tion, aca­d­e­m­ic cours­es, devel­op­ment in high­er edu­ca­tion, edu­ca­tion via satel­lite and on line prob­lem solv­ing and dis­cus­sion through video con­fer­enc­ing. There are var­i­ous Cloud based E learn­ing facil­i­ties from open source to com­mer­cial for the edu­ca­tors and appren­tices that are dis­cussed below:

Mul­ti­me­dia: A com­bi­na­tion of text, graph­ics, ani­ma­tion, audio and video to enhance the online learn­ing process that helps the e -

learn­er users to grasp the ped­a­gogy and con­cept maps asso­ci­at­ed with tech­ni­cal con­cepts of the edu­ca­tion­al mate­ri­als.

Inter­ac­tiv­i­ty Skills: An instruc­tion­al strat­e­gy that helps a learn­er prac­tice what they have learned and imple­ment them in their behav­ioral inter­ac­tion.

Book­mark­ing: With the advance­ment of tech­nol­o­gy, Cloud based E learn­ing can be ben­e­fi­cial to the users in the com­fort of their home and the will­ing­ness to start and com­mence the course accord­ing to their time­line with pref­er­ence to the job at their dis­pos­al.

Search: The tech­nol­o­gy helps the e- learn­er user to search the par­tic­u­lar infor­ma­tion required to com­plete task while on the move.

Notes and Study Mar­tial: The smart users mark and save their own inter­est­ing top­ics of a course that con­tain the most impor­tant infor­ma­tion on the web for the longer use. This facil­i­ty is avail­able on all the gad­gets like tablets, smart phones PDA’S and many more.

Domain Experts: While access­ing the inter­net, the E‑learner user can eas­i­ly access to sub­ject experts through chat or online dis­cus­sion on a par­tic­u­lar top­ic of their inter­est.

Infra­struc­ture as a ser­vice: Com­put­er- based train­ing pro­vides deliv­ery of train­ing or edu­ca­tion through elec­tron­ic media such as inter­net, through pro­vid­ing man­u­al­ly con­fig­ured Infra­struc­ture bare met­al machines and also vir­tu­al machines and many more. It also pro­vides learn­ing man­age­ment sys­tem through soft­ware such as web cours­es that helps edu­ca­tors and smart users in their knowl­edge base.

5.  CLOUD COMPUTING PLATFORM: ARCHITECTURE AND ITS LAYERS

Fig1 Architecture of Cloud Based E‑Learning System.

Cloud com­put­ing is every­where. It reduces the time from sketch­ing out appli­ca­tion archi­tec­ture to actu­al deploy­ment and incor­po­rates vir­tu­al­iza­tion, on-demand deploy­ment, Inter­net deliv­ery of ser­vices, and open source soft­ware for its users. Cloud com­put­ing archi­tec­ture con­sist of two com­po­nents, the front end-that com­pris­es the client device i.e. Cloud Soft­ware, Vir­tu­al­iza­tion Soft­ware or maybe Man­age­ment Soft­ware. The back end- that is the cloud itself that includes tech­niques of data stor­age sys­tem, man­ag­ing of high end servers and the com­put­er appa­ra­tus­es. Clus­ter of these clouds make a whole cloud com­put­ing sys­tem [4]. Cloud ser­vice providers tend to offer ameni­ties that can be assem­bled into three clus­ters: soft­ware as a ser­vice, plat­form as a ser­vice, and infra­struc­ture as a ser­vice. These cat­e­gories group togeth­er

The var­i­ous lay­ers.

Soft­ware as a ser­vice (SaaS): Soft­ware as a ser­vice pro­vides busi­ness solu­tions avail­able on pay-per-use bassinet. A com­plete appli­ca­tion offered as a ser­vice on demand. By remov­ing com­plex­i­ty of the IT envi­ron­ment and pro­vide smart busi­ness solu­tions to their smart users.

Plat­form as a Ser­vice (PaaS): Plat­form as a Ser­vice offers base envi­ron­ment ready for orga­niz­ing appli­ca­tions on cloud with­out has­sles of man­ag­ing the cloud infra­struc­ture. Com­mer­cial exam­ples of PaaS include the Google Apps engine

Infra­struc­ture as a Ser­vice (Iaas): Infra­struc­ture as aSer­vice deliv­ers basic com­po­nents such as Servers, Net­work and Stor­age on-demand, Self-ser­vice, and Pay peruse basis that are pooled and made avail­able to han­dle work­loads that range from appli­ca­tion com­po­nents to high per­for­mance com­put­ing appli­ca­tions [5].

Desk­top as a ser­vice (Daas): Desk­top as a ser­vice pro­vid­ed through cloud com­put­ing in which the Ser­vice provider can pro­vide the var­i­ous desk­top plat­forms to the end user of choice of var­i­ous con­fig­u­ra­tions and var­i­ous oper­at­ing envi­ron­ments. It is basi­cal­ly avail­able in com­mer­cial and also in open source plat­forms.

6.  CLOUD COMPUTING BASED CLOUD BASED E LEARNING SOLUTIONS

The Cloud based E learn­ing can­not entire­ly replace edu­ca­tors; it is mere­ly an updat­ing for tech­nol­o­gy, con­cepts, tools and ideas that gives new con­tent in the field of edu­ca­tion. The edu­ca­tors and stu­dents are play­ing promi­nent roles and con­tribute in devel­op­ing and mak­ing use of Cloud based E learn­ing cloud. This uni­fied learn­ing approach is improv­ing the edu­ca­tion­al act. Cloud based E learn­ing cloud is a new jour­ney of cloud com­put­ing tech­nol­o­gy in the field of Cloud based E learn­ing, which is future Cloud based E learn­ing infra­struc­ture that includes all the need­ed hard­ware and soft­ware com­put­ing resources engag­ing in learning[6]. In cloud based Cloud based E learn­ing sys­tems, the orga­ni­za­tions are respon­si­ble for con­tent cre­ation, man­age­ment and deliv­ery while the cloud ser­vice providers respon­si­ble for sys­tem build­ing, advance­ment, man­age­ment and main­te­nance. The orga­ni­za­tions are charged accord­ing to the usage that direct­ly depends on the num­ber of stu­dents. There is numer­ous Clouds based E learn­ing solu­tions from open source to com­mer­cial and at least two enti­ties involved in aloud based E learn­ing sys­tem: the stu­dents and the instruc­tors.

8.  BENEFITS AND CHALLENGES OF USING CLOUD

Cor­po­ra­tions are pro­gres­sive­ly con­scious of the busi­ness val­ue that cloud com­put­ing car­ries and are tak­ing steps in the direc­tion of evo­lu­tion to the cloud. This smooth evo­lu­tion involves a sys­tem­at­ic under­stand­ing of the ben­e­fits as well as chal­lenges involved. Like any new tech­nol­o­gy, the imple­men­ta­tion of cloud com­put­ing is not free from issues. Some of the most impor­tant ben­e­fits and chal­lenges are dis­cussed below.

8.1  Benefits of using Cloud Computing

Con­ve­nience and con­tin­u­ous avail­abil­i­ty: Pub­lic clouds offer ser­vices that are acces­si­ble wher­ev­er the end user might be posi­tioned. This type of approach enables easy access to infor­ma­tion and accom­mo­dates the require­ments of users in dif­fer­ent time zones and geo­graph­ic loca­tions.

Cost Effi­cien­cy: This is one of the biggest ben­e­fits of cloud com­put­ing as the cloud is in gen­er­al avail­able at much cheap­er rates. This is achieved by the elim­i­na­tion of the invest­ment in stand-alone soft­ware or servers.

Resilien­cy and Redun­dan­cy: A cloud deploy­ment is typ­i­cal­ly built on a robust archi­tec­ture thus pro­vid­ing resilien­cy and redun­dan­cy to its users.

Bet­ter Stor­age Capac­i­ty: Cloud accom­mo­dates much more data on a serv­er com­pared to a per­son­al com­put­er. It offers bound­less stor­age capac­i­ty and elim­i­nates wor­ries of the e- user about run­ning out of stor­age space and at the same time.

Easy to get the lat­est and great­est updates: Soft­ware updates are also han­dled by the cloud ven­dor and occur sev­er­al times a year at no price to the cus­tomer. This helps the user to remain up-to-date with ongo­ing busi­ness demands.

Improved infor­ma­tion secu­ri­ty: Data con­fi­den­tial­i­ty issues such as data loca­tion and seg­re­ga­tion, and priv­i­leged access con­trol, become greater in the cloud. Threats intro­duced by cloud com­put­ing infra­struc­tures include new types of priv­i­lege esca­la­tion vul­ner­a­bil­i­ties from vir­tu­al machine to vir­tu­al machine.

Orga­ni­za­tions are much more con­cern about the safe­ty of the user’s data and dis­cov­ers new secu­ri­ty solu­tions day by day.

8.2  Challenges of Cloud Computing

Ensur­ing ade­quate per­for­mance: The intrin­sic restric­tions of the Inter­net apply to cloud com­put­ing.

These enact­ment lim­i­ta­tions can take in the form of inter­rup­tions caused by traf­fic spikes, strikes caused by

Mali­cious traffic/attacks, haste in the serv­er and many more. Ensur­ing ade­quate secu­ri­ty: Sev­er­al cloud-based appli­ca­tions con­tain pri­vate data and indi­vid­ual infor­ma­tion. So, one of the

cru­cial bar­ri­ers cloud providers have had to over­whelm is the per­cep­tion that

Cloud-based ameni­ties are less secure than desk­top based or dat­a­cen­ter-based ser­vices.

Per­for­mance and Band­width Cost: Com­pa­nies can save mon­ey on hard­ware but they have to spend more for the band­width. This can be a low cost for small­er appli­ca­tions but can be sig­nif­i­cant­ly high for the data inten­sive appli­ca­tions. Deliv­er­ing inten­sive and com­plex data over the net­work requires suf­fi­cient band­width. Because of this, many busi­ness­es are wait­ing for a reduced cost before switch­ing to the cloud.

Harm­ful com­pe­ti­tion: Too many com­pa­nies are enter­ing in the cloud envi­ron­ment and crowd the stage.

This result is a vir­tu­al scrap where some are not afraid of using erro­neous pro­ce­dures to gain the upper hand.

This can include false claims or try­ing to dam­age the rep­u­ta­tion of a com­peti­tor.

Major fail­ures: The major chal­lenge to cloud com­put­ing is how it address­es the secu­ri­ty and pri­va­cy con­cerns of busi­ness­es think­ing of accept­ing it. Issues relat­ed to data secu­ri­ty need to be tak­en more seri­ous­ly by the ven­dors, par­tic­u­lar­ly the big play­ers that ful­ly trust on the cloud data stor­age.

Polit­i­cal and Legal Issues: Cloud com­put­ing legal issues result from where a cloud provider retains impor­tant data of the con­sumer. The data cen­ters of the cloud ser­vice providers (CSP) may be locat­ed beyond the bound­aries of the client’s nation. This arise the polit­i­cal and legal issues as we have to ensure that CPS

Com­plies with that country’s busi­ness poli­cies and reg­u­la­tions.

9.  FUTURE SCOPE OF RESEARCH

Though the con­cept of Cloud based learn­ing plat­forms gain­ing pop­u­lar­i­ty. How­ev­er, lot of work is required tube done to make it more pop­u­lar and adopt­able by the all. Col­lab­o­ra­tive efforts are need­ed to make Cloud based E‑Learning as a main stream mode of edu­ca­tion. The future research includes the fol­low­ing prospects:

1. The huge plat­form of mul­ti­lin­gual e‑Contents is required to be evolved to accom­mo­date all the streams of edu­ca­tion.
2. Open source clouds for E learn­ing must pro­vide Soft­ware as a ser­vice, Plat­form as ser­vice and also infra­struc­ture as ser­vice for E- learn­ing pur­pose.
3. More uni­ver­si­ties and col­leges must sup­port e‑Learning and cloud based Archi­tec­ture.
4. Devel­op­ment of online edu­ca­tion based poli­cies and reg­u­la­tions.

10.  CONCLUSION

Cloud based E learn­ing is an emerg­ing aspect of dis­tance edu­ca­tion that pro­vides any-time, any­where edu­ca­tion­al approach. Advance appren­tices always look­ing for up-gra­da­tion of their knowl­edge and tech­ni­cal skills and those who want extra skills are going towards it. Many stu­dents are adopt­ing this tech­nol­o­gy. With pro­gres­sion of cloud based Infra­struc­tures, increased bud­get and open source ini­tia­tives the future of E- Learn­ing is gain­ing pop­u­lar­i­ty day by day. The advent of cloud envi­ron­ment mak­ing Cloud based E‑learning effec­tive and con­ve­nient to access. Peo­ple of all age­group­sare con­nect­ed through the Inter­net and mobile devices, thus increas­ing

aware­ness. In short, we can con­clude Open source cloud based E- learn­ing facil­i­tat­ing plat­form for learn­ing in effec­tive ways.
