Cloud computing has become an attractive target for attackers as the mainstream technologies in the cloud, such as the virtualization and multitenancy, permit multiple users to utilize the same physical resource, thereby posing the so-called problem of internal facing security. Moreover, the traditional network-based intrusion detection systems (IDSs) are ineffective to be deployed in the cloud...

Cloud computing is a new discussion in enterprise IT. It has already become popular in terms of distributed technology in some companies. It enables managers to setup and run the intended businesses by avoiding excessive spending on computers, software and hiring expert staff, which proves to be cost effective. Cloud computing also helps users pay for the IT services without spending massive am...

In recent years, many organizations have been confronted with cloud computing deployment decisions. One critical decision is to balance between discontinuation of in-house systems and adoption of cloud computing systems. Previous researchers usually investigated the determinants that influence cloud adoption only from a new IT adoption perspective. However, when a firm makes its decision to rep...

We now begin to trace the journey towards a star. How long does this take? The answer is surprisingly short: a good many clouds already contain new stars and these stars tend to be young. The typical cloud cannot spend long, if any time at all, in a dormant state. The first challenge is to accumulate gas into a molecular cloud. One dilemma is to decide what occurred first: the production of the...

-------------------------------------------------------------------ABSTRACT--------------------------------------------------------------The topic of ‘‘the cloud’’ has attracted significant attention throughout the past few years. It allows resource sharing that includes software, platform and infrastructure by means of virtualization. Cloud Adoption in Oil & Gas companies have approached cloud...

Group phenomena for droplets in a spray have often been analyzed on the basis of the quasi-steady assumption even though this assumption has not been completely justified. In this paper the applicability of the quasi-steady assumption to the vaporization of spherical droplet clouds is first analyzed qualitatively by considering the magnitudes of appropriate characteristic scales. Then the gover...

Recent years have witnessed the development of cloud computing. However, there also come some security concerns in cloud computing environment, such as emerging network attacks and intrusions, and instable cloud service provision due to flexible cloud infrastructure and resources. To this end, we research on the trusted computing in cloud computing environment. Specifically, in this paper, we p...

This study aims to understand the influence of the ethical and legal issues on cloud computing adoption in the field of genomics research. To do so, we adapted Diffusion of Innovation (DoI) theory to enable understanding of how key stakeholders manage the various ethical and legal issues they encounter when adopting cloud computing. Twenty semi-structured interviews were conducted with genomics...

The cloud services market exhibits unique characteristics such as instant accessibility, fluctuating demand and supply, and interruptible service provision. Various pricing mechanisms exist in current industry practice, however, none is comprehensive enough to capture all these features. In my work, I identify key factors related to cloud computing pricing. My dissertation includes three essays...

Cloud computing has been marketed as having multiple benefits. However, organizations remain hesitant to adopt it. For cloud computing providers, it is important to understand how to influence organizations’ adoption decision. However, extant literature has focused on cloud computing’s architecture, potential applications, and costs and benefits without understanding how organizations’ percepti...
