Professor, Sinhgad Institute of Management, Pune-4 MCA Students, Sinhgad Institute of Management, Pune-4 Abstract The origin of the term is obscure, but it appears to derive from the practice of using drawings of stylized s to denote networks in diagrams of and communications systems. Cloud Computing is a style in which scalable and flexible IT functionalities are delivered as a service to external customers using Internet technologies. This implementation has been used in both IT sector and Educational sector, and this paper focus on comparative study of usage of in educational sector vs. IT sector. In Educational sector, this technology has been used by students and faculties for accessing and assigning some educational work over internet. Students and administrative personnel have the opportunity to quickly and economically access various application platforms and resources through the web pages ondemand. Hence this research paper is mainly focuses on effectiveness and security of applications over traditional ERP system in educational sector. This also focus on how implementation of is possible in less cost as compared to traditional ERP system in educational sector. As well as it considers cost for implementing with respect to various services models like Infrastructure as a service(iaas), Software as a service (SAAS) and Platform as a service( PAAS) as per users requirement. Keywords: Cloud, Network, Educational Sector, Implementation etc.. Introduction Cloud is latest trend in IT world. It is Internet-based, whereby shared resources, software and information, are provided to computers and other devices on-demand, like the electric grid. This technology has the capacity to admittance a common collection of resources on request. It is proving extremely striking to cash-strapped IT departments that are wanted to deliver better services under pressure. In recent years has become a growing interest for organizations looking to reduce their IT costs by offloading infrastructure and software costs onto 3rd party organizations who offer software-as-a-service (SaaS) (e.g.google Apps), platform-as-a-service (PaaS) (e.g. Google App Engine), and infrastructure-as-a-service (IaaS) (e.g. Amazon EC).. Theoretical Background of The Study Cloud Computing is a style in which scalable and flexible IT functionalities are delivered as a service to external customers using Internet technologies. This implementation has been used in both IT sector and Educational sector. In Educational sector, this technology has been used by students and faculties for accessing and assigning some educational work over internet. Students and administrative personnel have the opportunity to quickly and economically access various application platforms and resources through the web pages on-demand. By using, it is required to collect various data by conducting online survey in educational institutes and their respective universities also. The main advantage of using is that, student will get proper knowledge and faculties will handle and maintain this implemented technology appropriately. 3. Review of Literature Researchers has done extensive literature review on various aspects of and their services models. Few of them are as follows- 3. Daniel D. Sunil (0): According to him, can be unsecure due to some issues like attack from unauthorized users. The attack can be of two type s viz. targeting the whole or targeting single service. In both the cases, the security issues are needed to be handled. This can be done with the help of Access Control List (ACL). ACL (Access Control List). It contains the set of access rules, which can be assigned to the authorized user. The ACL works along with the Security manager in order to avoid unauthorized access to the Cloud. 3. F. A. Alvi, B.S Choudary, N. Jaferry, E.Pathan: This section includes survey conducted by international data corporation (IDC).

Testing of Hypotheses Various statistical tools used to test the hypotheses. If the replies of a majority of the respondents support a hypothesis then that hypothesis will be considered as confirmed. Otherwise it will be considered as rejected. The data connected with the hypothesis and obtained from respondents has been used for this purpose 7. Hypothesis : The first hypothesis of the study is Cloud services are cheaper than the existing ERP system. For testing this hypothesis, null and alternative hypothesis are set and which are as follows- H 0 : There is no difference between cost of Cloud services and ERP system. H : Cloud services are cheaper than the existing ERP system. As the sample sizes are <30 therefore normal approximations are satisfied. In this case Z-test and as one proportion is involved. As alternative hypothesis is in terms than hence rejection area is towards only one side hence it is one tail test (t-test). Table No. 0: Z Statistics One-Sample Test T df Sig. (-tailed) 95% Confidence Interval of the Difference Lower Upper As per Table No. 0, P value is 0.00 is < 0.05 hence reject H 0 (Null hypothesis) and accept H that is hypothesis of the study. Hence it proves that Cloud services are cheaper than the existing ERP system 7. Hypothesis : Use of Cloud increases the resource flexibility level in educational sector. According to data collected from 33 people, 7 people agree upon the increases resource flexibility. For testing this hypothesis, null and alternative hypothesis are set and which are as follows- H 0 : Cloud doesn t affect the resource flexibility level in educational sector. H : Use of Cloud increase the resource flexibility level in educational sector. Table No. : ANOVA for Flexibility for Groups Sum of Squares df Mean Square F Sig. Between Groups Within Groups Total Volume, Issue 0, October 03 Page 95

6 As per above table, P value is which is less than α=0.05, the level of significance. Therefore, it is enough evidence to reject the Null hypothesis and accept H that is hypothesis of the study. Hence it proves that Use of Cloud increases the resource flexibility level in educational sector 7.3 Hypothesis 3: Cloud Computing services are more secure. Null and alternative hypothesis are- H 0 : Cloud Computing services are not secure. H : Cloud Computing services are more secure. For testing this hypothesis, one sample t test has been applies. T- Statistics for the same has been shown in following table. Table No. : One Sample Test Statistics 95% Confidence Interval of the Difference T Do Sig. (-tailed) Lower Upper As per above table, P value is which is less than α=0.05, the level of significance. Therefore, it is enough evidence to reject the Null hypothesis and accept alternative hypothesis that, Cloud Computing services are more secure. 7.4 Hypothesis 4: Cloud Computing is applicable in all IT and educational sectors. As per primary data, 93.9% respondents agreed that, is applicable in IT and educational sector. H 0 : Cloud is not applicable in educational sector. H : Cloud Computing is applicable in all IT and educational sectors. Table No. 3: One Sample Test Statistics 95% Confidence Interval of the Difference T df Sig. (-tailed) Lower Upper As per above table, P value is which is less than α=0.05, the level of significance. Therefore, it is enough evidence to reject the Null hypothesis and accept alternative hypothesis that, Cloud Computing is applicable in all IT and educational sectors. 8. Findings We have collected data from 55 respondents from which respondents are IT professionals and rests of the 33 respondents are from educational institutes. 93 percent educational institutes are aware about. As per the educational institute s opinion, the cost to implement lies mainly between Rs.30, ,000 only. It is seen that the percentage of PaaS & SaaS requires high implementation cost (Rs /-) as compared to IaaS. 90 percent educational institutes agreed that is cheaper than traditional ERP system and they are satisfied with Study reveals that services are more reliable with average value 4.0 followed by accessibility with average value 3.90, security is high with average value Further resources flexibility with average value is 3.9 and resource availability with average value is 3.8. Most of the educational institutes used Hybrid Deployment model as compared other models. As per IT and Educational sectors point of view, security of is very high. 9. Conclusion In today s fast moving life people want all the facilities at their maximum convenience which is provided by the over the internet, this is one of the reasons for the growing popularity of. Still a large proportions of people today refrain themselves from using these facilities due to the security reasons or reliability with. This means that the IT professionals usually go for just internet services or intranet within the organization without implementing the which results in increased cost. Ratio for awareness of in educational sector is very high as compared to the unawareness Effectiveness of services is very high Volume, Issue 0, October 03 Page 9

7 From the research the researchers can also conclude that the organizations using services uses the same for all their connectivity issues. Also a few other products such as Drop Box, Google Drive have increased the awareness in the people. The research also shows that most of the people using these facilities view it as time saving and cost saving. Educational sector can decrease the paper work by implementing the services. The cost incurred for the software licensing can be reduced by sharing software with the help of SaaS. 0. Suggestions & Recommendations The respondents have put forward certain suggestions and recommendations which have been summarized into a more organized form by the researcher 0. Suggestions The use of should be promoted by organizations. Services charges for should be minimized. All the different models should be available at low implementation cost. Cloud should be promoted for the personal use. The technology should be made simpler, user- friendly and easily accessible. The should not only be available to faculties or management in institutions but also should be available students. The platform requirement for accessing the should be should be minimized such as Efforts should be made to decrease the technical problems and security issues regarding the. Different security measures should be applied in order to provide security for data and services provided by. 0. Recommendations The following are the recommendations for increasing the use and popularity of facilities: Proper training is given to employees by the implementing organization to access the applications, resources or software s over the internet, then the time and cost incurred can be minimized. Create a trust in organizations towards security of the services and data. Cloud services implementation and access should be available at lower cost.
