    While most research regarding adoption of cloud computing by companies covers countries with highly developed IT infrastructure, cloud computing is actually used also in less IT-mature countries. Still, companies address cloud computing differently in countries with different levels of IT-maturity. This research explores cloud computing adoption factors in less IT-mature countries having Turkey as the example. Embracing an exploratory approach, we investigated five large Turkish companies. The results show that the main adoption factors in favour of cloud computing are “cost”, “distributed organisational structure”, “mobility of the employees”, and “end-user satisfaction”, while “security”, “critical business processes”, “loss of control over data and systems”, and “technical infrastructure of the region in terms of broadband” are the factors that make companies cautious about cloud computing. The main difference between Turkey and more IT-mature countries with respect to cloud computing adoption factors is inadequate broadband access and lack of knowledge on cloud computing

    Part 3: Creating Value through ApplicationsInternational audienceCloud computing has received increasing interest from enterprises since its inception. With its innovative information technology (IT) services delivery model, cloud computing could add technical and strategic business value to enterprises. However, cloud computing poses highly concerning internal (e.g., Top management and experience) and external issues (e.g., regulations and standards). This paper presents a systematic literature review to explore the current key issues related to cloud computing adoption. This is achieved by reviewing 51 articles published about cloud computing adoption. Using the grounded theory approach, articles are classified into eight main categories: internal, external, evaluation, proof of concept, adoption decision, implementation and integration, IT governance, and confirmation. Then, the eight categories are divided into two abstract categories: cloud computing adoption factors and processes, where the former affects the latter. The results of this review indicate that enterprises face serious issues before they decide to adopt cloud computing. Based on the findings, the paper provides a future information systems (IS) research agenda to explore the previously under-investigated areas regarding cloud computing adoption factors and processes. This paper calls for further theoretical, methodological, and empirical contributions to the research area of cloud computing adoption by enterprises

    Understanding the Determinants of Cloud Computing Adoption for High Performance Computing

    Within the complex context of high performance computing (HPC), the factors influencing technology adoption decisions remain largely unexplored. This study extends Diffusion of Innovation (DOI) and Human-Organization-Technology fit (HOT-fit) theories into an integrated model, to explore the impact of ten factors on cloud computing adoption decisions in the HPC context. The results suggest that adopters and non-adopters have different perceptions of the indirect benefits, adequacy of resources, top management support, and compatibility of adopting cloud computing for HPC. In addition, perceptions of the indirect benefits and HPC competences can be used to predict the cloud computing adoption decision for HPC. This is one of the first studies in the information systems (IS) literature exploring the factors impacting the cloud computing adoption decision in the important context of HPC. It integrates two influential technology adoption theories and enhances understanding of the key factors influencing organizations’ cloud computing adoption decisions in this context

    Cloud computing adoption in regional councils

    Cloud computing is becoming increasingly important in information technology as an enabler for improved productivity, efficiency and cost reduction; and is expected to offer benefits for public sector organisations. Cloud computing has the potential to improve the reliability and scalability of information technology systems, which allows organisations such as regional municipal governments to focus more on their core business and strategy. Research about the use of cloud computing in the public sector in general is limited. There is a lack of exploratory studies that provide an in-depth and holistic investigation of the factors perceived to influence the adoption of cloud computing. There are no empirical studies about the factors that are perceived to influence the adoption of cloud computing in reference to Australia. This research aimed at exploring perceptions of the potential for value creation from cloud computing in regional councils, to identify factors that are likely to influence adoption of cloud computing including factors that need to be considered when planning to adopt cloud, anticipated benefits of cloud adoption, and challenges and issues that faced cloud adoption. This research aimed to improve understandings related to the factors that influence cloud computing adoption decision making in regional municipal governments. The research employed a mixed method approach (qualitative and quantitative). In-depth interviews of Australian councils’ IT managers were conducted with the aim of providing insights into the factors that are perceived likely to influence adoption of cloud computing including factors that need to be considered when planning to adopt cloud, anticipated benefits of cloud adoption, and challenges and issues that faced cloud adoption. Survey data from 480 IT staff across 47 local government councils were collected to confirm the findings of the exploratory stage. The factors that were examined included: compatibility, complexity, cost, security concern, top management support, organisation size, government regulation, and information intensity. The findings of this research are expected to assist in making investment decisions on cloud computing adoption

    Acceptance and Use of E-Learning Based on Cloud Computing: The Role of Consumer Innovativeness

    Get PDF
    Cloud computing and E-learning are the inevitable trend of computational science in general, and information systems and technologies in specific.However, there are not many studies on the adoption of cloud-based E-learning systems. Moreover, while there are many papers on information system adoption as well as customer innovativeness, the innovativeness and adoption in the same model seems to be rare in the literature. The study combines the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) and consumer innovativeness on the adoption of E-learning systems based on cloud computing. A survey was conducted among 282 cloud-based E-learning participants and analyzed by structural equation modeling (SEM). The findings indicate that the adoption of cloud-based E-learning is influenced by performance expectancy, social influence, hedonic motivation, and habit. Interestingly, although innovativeness is not significant to use intention, it has a positive effect on E-learning usage which is relatively new in Vietnam

    DCDIDP: A distributed, collaborative, and data-driven intrusion detection and prevention framework for cloud computing environments

    Get PDF
    With the growing popularity of cloud computing, the exploitation of possible vulnerabilities grows at the same pace; the distributed nature of the cloud makes it an attractive target for potential intruders. Despite security issues delaying its adoption, cloud computing has already become an unstoppable force; thus, security mechanisms to ensure its secure adoption are an immediate need. Here, we focus on intrusion detection and prevention systems (IDPSs) to defend against the intruders. In this paper, we propose a Distributed, Collaborative, and Data-driven Intrusion Detection and Prevention system (DCDIDP). Its goal is to make use of the resources in the cloud and provide a holistic IDPS for all cloud service providers which collaborate with other peers in a distributed manner at different architectural levels to respond to attacks. We present the DCDIDP framework, whose infrastructure level is composed of three logical layers: network, host, and global as well as platform and software levels. Then, we review its components and discuss some existing approaches to be used for the modules in our proposed framework. Furthermore, we discuss developing a comprehensive trust management framework to support the establishment and evolution of trust among different cloud service providers. © 2011 ICST
