Cloud computing has become a dominant IT trend during the past two years for its potential to remarkably change the technology and business landscape. Although a lot have been discussed, its impacts on organizational IT strategy have not yet been fully addressed. In order to learn how cloud computing is going to bring changes to organizational IT strategy, we conducted interviews with CIOs/IT d...

Multimedia cloud is a specific cloud computing paradigm, focusing on how cloud can effectively support multimedia services. For multimedia service providers (MSP), there are two fundamental concerns: the quality of service (QoS) and the resource cost. In this paper, we investigate these two fundamental concerns with queueing theory and optimization methods. We introduce a queueing model to char...

Bat algorithm (BA) is a novel stochastic global optimization algorithm. Cloud model is an effective tool in transforming between qualitative concepts and their quantitative representation. Based on the bat echolocation mechanism and excellent characteristics of cloud model on uncertainty knowledge representation, a new cloud model bat algorithm (CBA) is proposed. This paper focuses on remodelin...

Cloud computing is moving from the pre-adoption to the post-adoption phase with many cloud client organizations having established relationships with cloud providers. Hence, the most critical cloud computing question for information technology (IT) executives shifts from the issue of adopting cloud computing to the issue of managing existing relationships with cloud providers. Under which condi...

Software applications accessible over the web are typically subject to very dynamic workloads. Since cloud elasticity provides the ability to adjust the deployed environment on the fly, modern software systems tend to target cloud as a fertile deployment environment. However, relying only on native elasticity features of cloud service providers is not sufficient for modern applications. This is...

Abstract—A new BN structure learning method using a cloud-based adaptive immune genetic algorithm (CAIGA) is proposed. Since the probabilities of crossover and mutation in CAIGA are adaptively varied depending on X-conditional cloud generator, it could improve the diversity of the structure population and avoid local optimum. This is due to the stochastic nature and stable tendency of the cloud...

Using data from 192 undergraduates asked to imagine a stressful experience, this study finds support for two primary contentions of a dual-process theory of supportive message outcomes: (a) message content impacts anticipated affect improvement (AAI) when processing motivation is high but not when low and (b) processing extent mediates the relationship between verbal person centeredness (VPC) a...

Cloud Computing has become one of the popular buzzwords in the IT area after Web2.0. This is not a new technology, but the concept that binds different existed technologies altogether including Grid Computing, Utility Computing, distributed system, virtualization and other mature technique. Business Process Management (BPM) is designed for business management using IT infrastructure to focus on...
