Cloud computing is a pervasive computing paradigm that has revolutionized how computer infrastructure and services are delivered. Current research trends on cloud computing have been focused on the technology, applications, costs, benefits, and security of cloud computing at the organizational level within small and medium sized enterprises. Little research attention has been paid on adoption and usage of cloud computing at educational establishments and how contextual factors can influence diffusion and adoption of cloud computing. Universities in developing countries are faced with challenging socio-economic and political constraints that limit their ability to invest in expensive information systems to compete on the global stage. Using constructs from the diffusion of innovation theory and the technology acceptance model, this paper proposes a model that takes account of contextual, economic, and technological influences in the perception and adoption of cloud computing at universities in sub-Saharan Africa. Results from a pilot study, based on the model, through a survey of university lecturers and IS experts shows reliability and validity of the instrument and supports its usage for a more extensive study. Implications, potential contributions to research, and suggestions for future study are discussed. 相似文献

Cloud computing is an IT service paradigm that can, if used meaningfully, enhance traditional health IT approaches and offer major benefits to the healthcare industry. However, its adoption by healthcare organizations has been accompanied by diverse challenges that could impede its meaningful use. Decisions about its adoption should be made after serious consideration of relevant industry-specific factors. Whereas the literature has focused on cloud computing adoption in general, the industrial specificities that influence the decision to adopt cloud computing in the healthcare context have yet to be systematically addressed. We reviewed empirical studies on both information systems and medical informatics to investigate the determinant factors of the cloud computing adoption decision in healthcare organizations and the industrial specificities of those factors. Based on the results of our review, we proposed a conceptual framework of cloud computing adoption studies in healthcare and made seven recommendations for related future research. Our research contributes to the theory by providing a comprehensive list of industry-specific factors that influence cloud computing adoption decisions in healthcare and explains their specificities for the healthcare industry. For practitioners, the identified factors serve as a checklist that informs healthcare organizations’ decision making regarding cloud computing adoption. 相似文献

Cloud computing has become the buzzword in the industry today. Though, it is not an entirely new concept but in today's digital age, it has become ubiquitous due to the proliferation of Internet, broadband, mobile devices, better bandwidth and mobility requirements for end-users (be it consumers, SMEs or enterprises). In this paper, the focus is on the perceived inclination of micro and small businesses (SMEs or SMBs) toward cloud computing and the benefits reaped by them. This paper presents five factors influencing the cloud usage by this business community, whose needs and business requirements are very different from large enterprises. Firstly, ease of use and convenience is the biggest favorable factor followed by security and privacy and then comes the cost reduction. The fourth factor reliability is ignored as SMEs do not consider cloud as reliable. Lastly but not the least, SMEs do not want to use cloud for sharing and collaboration and prefer their old conventional methods for sharing and collaborating with their stakeholders. 相似文献

Cloud computing is now a global trend and during the past decade, has drawn attention from both academic and business communities. Although the evolution of cloud computing has not reached the maturity level, there is still adequate research about the topic. The main purpose of this paper is to examine the development and evolution of cloud computing over time. A content analysis was conducted for 236 scholarly journal articles, which were published between 2009 and 2014 in order to (i) identify the possible trends and changes in cloud computing over the six years, (ii) compare publishing productivity of journals about the cloud computing subject, and (iii) guide future research about cloud computing. The results show that the majority of the cloud computing research is about “cloud computing adoption” (19%), and it was followed by the “legal and ethical issues” of cloud computing (15%). It is also found that “cloud computing for mobile applications” (6%), “benefits & challenges of cloud computing” (5%) and “energy consumption dimension of cloud computing” (4%) are the least attention-grabbing themes in the literature. However, “cloud computing for mobile applications” and “energy consumption dimension of cloud computing” themes have become popular in the last two years, so they are expected to be trendy topics of the near future. Finally, another finding of this study is that the majority of the articles were published by engineering, information systems or technical journals such as “IT Professional Magazine”, “International Journal of Information Management” and “Mobile Networks and Applications”. It seems as if this topic is generally ignored by the managerial and organizational journals even though the impact of cloud computing on organizations and institutions is immense and is in need of investigation. 相似文献

Cloud computing is a new information technology (IT) paradigm that promises to revolutionize traditional IT delivery through reduced costs, greater elasticity, and ubiquitous access. On the surface, adopting cloud computing requires a firm to address many of the same concerns they face in adopting any enterprise IT. However, cloud technologies also offer new pricing and deployment strategies that are unavailable in traditional enterprise solutions. It is unclear how previous research frameworks of enterprise IT adoption relate to these new adoption strategies. To bridge this gap in the literature, our study uses the technology–organization–environment (TOE) framework of innovation diffusion theory to develop a cloud service adoption model that deals with not only adoption intention, but also pricing mechanisms and deployment models. Our research model has been empirically tested using 200 Taiwanese firms. We found that: (1) Cloud adoption is still at its initial stage, since the adoption rates are very low; (2) the perceived benefits, business concerns, and IT capability within the TOE framework are significant determinants of cloud computing adoption, while external pressure is not; (3) firms with greater IT capability tend to choose the pay-as-you-go pricing mechanism; (4) business concern is the most important factor influencing the choice of deployment model, with higher concerns leading to private deployment options. 相似文献

The purpose of this research article is to identify the critical success criteria/factors that affect the cloud computing adoption and examine structure, reliability and validity of the criteria in the SMEs industry. This study considers nine types of criteria/factors with fifty-one sub-criteria, which have somewhat previously been used, and creates a ranking model that offers decision makers to measure the prior implementation of cloud computing adoption. A questionnaire-based survey research was used to collect data from 110 firms belonging to the SMEs industry in India. In this paper, the data collected was analysed by an integrated approach. Firstly, an Analytic Hierarchy Process approach was applied to find the significant fact of each criterion as the assessable indices of the cloud computing adoption. Secondly, an Exploratory Factor Analysis and Confirmatory Factor Analysis were used to examine structure, reliability and validity of the criteria. The data was tabulated in a Microsoft Excel sheet and then imported in SPSS (Statistical Package for the Social Sciences version 20) for analysis. The findings discovered that ‘Security and Privacy’, ‘Organizational Risk’, ‘Sharing and Collaboration’, ‘Confidentiality’, and ‘Integrity’ have a major effect on the adoption of cloud computing. The research was conducted in the SMEs industry in India, which may limit the generalizability of the findings. The findings and recommendations offer cloud computing service providers as well as users with a better understanding of what affects the cloud computing adoption feature, with a relevant understanding of the current scenario. The research aided in the application of the new technology of cloud computing adoption in the SMEs industry in India through the use of a wide range of criteria. The findings also help organizations study their information technology investments when applying cloud computing. 相似文献

Cloud computing is a current trend that reveals the next-generation application architecture and it is estimated that by 2013 the cloud market will have reached $8.1bn. While cloud services such as webmail, Flickr and YouTube have been widely used by individuals for some time, it not until relatively recently that organisations have began to use cloud services as a tool for meeting their IT needs. This study aims to investigate how cloud computing is understood by IT professionals and the concerns that IT professionals have in regard to the adoption of cloud services. The study was carried out in Taiwan and used a survey by interview approach to understand IT professionals’ understandings and concerns about cloud computing. The findings of the study suggest that while the benefits of cloud computing such as its computational power and ability to help companies save costs are often mentioned in the literature, the primary concerns that IT managers and software engineers have are compatibility of the cloud with companies’ policy, IS development environment, and business needs; and relative advantages of adopting cloud solutions. The findings also suggest that most IT companies in Taiwan will not adopt cloud computing until the uncertainties associated with cloud computing, e.g. security and standardisation are reduced and successful business models have emerged. 相似文献

The purpose of this study is to investigate the critical factors that will affect the decision to adopt cloud computing technology in developing countries, specifically in Taiwan's hospital industry. This study mainly integrates the TOE (Technology-Organization-Environment) framework and HOT-fit (Human-Organization-Technology fit) model to understand this issue. Information was collected by employing a questionnaire research design to hospital CIOs in Taiwan. The obtained results indicate that the 5 most critical factors are data security, perceived technical competence, cost, top manager support, and complexity. Further, among the proposed four dimensions the most important one is technology followed by human, organizational, and environmental factors. Finally, the results show that significant differences exist in CIO innovativeness, data security, compatibility, top manager support, adequate resource, and perceived industry pressure across different adopting groups. For practitioners, this study identifies key factors for hospitals to make an adoption decision toward cloud computing technology. As for academia, this study can be provided as a useful reference for future studies in this subject field. 相似文献

Small enterprises play an important role in the technology innovation and economic development of most countries all over the world, particularly in Taiwan. Due to a lack of financial resources and expertise, small enterprises tend to find novel ways to utilize IT resources in order to reduce IT adoption costs, to achieve better flexibility, business agility and scalability, and to react faster to market demands. Whereas Taiwan has been promoting cloud computing to help Taiwanese enterprises adopt more effective information technologies, we found that the service strategies of small cloud service providers are individually differentiated in order to survive in the competitive cloud computing market. This paper reports a case study of a small e-learning service provider and its four clients in Taiwan. Some novel insights are revealed through this case study and recommendations are provided accordingly. 相似文献

Reaching for the “cloud”: How SMEs can manage 总被引：1，自引：0，他引：1
Cloud computing is an emerging new computing paradigm for delivering computing services. The approach relies on a number of existing technologies e.g., the Internet, virtualization and grid computing. However, the provision of this service in a pay-as-you-go way through the popular medium of the Internet renders this computing service approach unique compared with currently available computing service modalities. This article highlights some aspects of this uniqueness and also explores some of the concerns that might be preventing some companies from adopting it. Notwithstanding these concerns, it is argued in this article that cloud computing is likely to prove commercially viable for many small and medium enterprises (SMEs) due to its flexibility and pay-as-you-go cost structure, particularly in the current climate of economic difficulties. A case study of a cloud experience by a British SME is also presented in this study in order to further highlight the perceived values of cloud computing in terms of cost and efficiency for real small enterprises. 相似文献

Today’s data is sensitive that requires privacy and security both from the cloud service providers (CSP) as well as from users in its all the form of data states: data at rest, while transferring data, enquiring data, and processing the data. Cloud computing has been applied in the health sector, national security services, banking and other business and companies that store confidential data into the cloud as we have seen in recent years. Therefore, information and data security is a crucial issue that needs to be addressed thoroughly in the cloud computing business. This research deals with the performance analysis of recent cloud data security models. This paper proposes cloud data security models based on Business Process Modeling Notations (BPMN) and simulation results can reveal performances issues related to data security as part of any organizations initiative on Business process management (BPM). 相似文献

This paper examines the key drivers of mobile marketing adoption intention by South African SMEs using a multi-perspective framework that combines elements in the technological, organisational and environmental contexts of the enterprises. Data was collected from a random sample of 205 SMEs from Gauteng, South Africa. Structural equation modelling was used to analyse the data. The results identified perceived relative advantage, perceived cost, top management support, employees’ IT capability, and customer pressure as important drivers of mobile marketing adoption intention. Of these factors, top management support emerged as the strongest driver of adoption intention. The implications of these findings for mobile marketers and others interested in accelerating the adoption of mobile marketing among SMEs are highlighted. 相似文献

As cloud computing has spread from the enterprise sector to individuals, there has been a growing need for research on the adoption of cloud computing at the individual level. However, relatively little research has investigated the differences and similarities between users and nonusers regarding the individual-level technology acceptance. To fill this gap, this study explored the differences and similarities between users and nonusers in the context of public cloud storage services of South Korea. Data (users = 210; nonusers = 187) were analyzed using structural equation modeling. For social influence, there was a significant difference between users and nonusers. For users, social influence was not a determinant for positive intention to use PCSS, whereas it was a determinant for nonusers. For other factors, there were no significant differences between the two groups, but each showed meaningful similarities: habit was the strongest predictor of the intention to use for both users and nonusers, whereas hedonic motivation was not an important concern for both; performance expectancy was a determinant for positive intention to use PCSS for both groups. Effort expectancy was a determinant for positive intention to use PCSS for users, whereas it was not a determinant for nonusers. These results can provide academic researchers and businesses with insights into individual-level adoption of cloud computing. 相似文献
