银行等金融机构的批处理规模越来越大,对IT中心的资源配置要求也越来越高。为提高IT中心的资源使用效率和配置灵活程度,优化业务流程和加速IT新技术应用,可通过重新梳理批处理业务流程,根据资源需求类型分解为流程任务的方式,将批处理流程队列按照任务特征分解为任务队列,配置合适的任务队列处理资源,在批处理过程中动态监控和调度资源;另一方面,以基础架构资源虚拟化为核心的云计算技术逐步成熟,使IT 中心的资源虚拟化、配置管理的精细化成为可能。介绍了一种针对银行批处理业务流程优化、以虚拟化资源配置来实现批处理的技术框架,实现批处理流程任务队列的并行计算和动态资源配置。通过Ctrix服务器资源虚拟化技术进行初步模拟验证,实验结果表明,该技术框架在批处理执行效率、资源使用和配置灵活性方面的优势,在具有大量批处理业务和集约化处理的领域（金融、证券、电子商务）,具有一定的应用和研究价值。 相似文献

云计算是信息时代的新型的计算模式,代表着下一代的互联网技术。资源调度和管理是云计算的关键技术之一,资源调度的目标包括满足用户服务质量、提高资源利用率、节点负载均衡等,为此有必要借助各种调度策略与各优化算法对资源调度方案进行优化,以提高任务和资源的匹配效率。聚类是将物理或者抽象的对象集合依据相似程度划分为若干类群,源于数学、统计和经济等领域,并广泛应用于很多领域。在云计算资源调度中,用户任务的资源需求特征异同,本文基于相似分治的思想,对用户任务进行聚类处理后优化调度是云计算资源调度研究的一个有效思路。实验仿真表明,任务聚类策略有效地提高了后续任务资源调度优化的效率。 相似文献

Discovering the potential of cloud computing in accelerating the search for curing serious illnesses
《International Journal of Information Management》2014,34(2):221-225
Derided, when it emerged in 2007 as a fad, cloud computing has proved to be a viable business model for remotely delivering IT services through the Web (and other media) on a pay-as-you-go basis. The flexibility of this emerging computing service has opened many possibilities for organizations. Drug companies and medical research centers are among those organizations that are likely to benefit from this new IT service model. As well as providing massive cost-savings, cloud computing could offer these organizations the opportunity to greatly enhance the efficiency of their operations. For cloud providers, this is a new field to expand their reach. The aim of this article is to explore this new development and the potential of cloud computing in contributing to the advancement of research in life science and explain why this IT service model (despite many of its problems) could be game-changer for companies engaged in this business. 相似文献

The mechanism of business analytics affordances enhancing the management of cloud computing data security is a key antecedent in improving cloud computing security. Based on information value chain theory and IT affordances theory, a research model is built to investigate the underlying mechanism of business analytics affordances enhancing the management of cloud computing data security. The model includes business analytics affordances, decision-making affordances of cloud computing data security, decision-making rationality of cloud computing data security, and the management of cloud computing data security. Simultaneously, the model considers the role of data-driven culture and IT business process integration. It is empirically tested using data collected from 316 enterprises by Partial Least Squares-based structural equation model. Without data-driven culture and IT business process integration, the results suggest that there is a process from business analytics affordances to decision-making affordances of cloud computing data security, decision-making rationality of cloud computing data security, and to the management of cloud computing data security. Moreover, Data-driven culture and IT business process integration have a positive mediation effect on the relationship between business analytics affordances and decision-making affordances of cloud computing data security. The conclusions in this study provide useful references for the enterprise to strengthen the management of cloud computing data security using business analytics. 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

Cloud computing's primary layer of security is its widespread adoption by businesses due to its ability to provide easy, on-demand network access to a large pool of configurable processing resources. Pressure from developed-world governments to keep up with the latest IT trends makes it challenging for colleges around the world to adopt cloud computing in engineering education. Although cloud computing as a concept has become more popular in recent times and quite a few studies have been conducted, the adoption and application level is still very low, particularly in developing countries. This study provides a realistic framework for gauging the sustainability of a company model. While digitalization is widely acknowledged to be crucial, the study's results reveal that the perceived available options for business model innovation depend not only on the value proposition itself but also on the position in the value network. The primary goal of this research is to create a cloud computing service provider business model that is built on circular economy principles and can guarantee the sustainable usage of cloud computing resources. 相似文献

Employing the literature on IT governance and the structuration theory of technology assimilation, this research develops a conceptual model to examine decision execution mechanisms of IT governance in post-adoption stages of CRM diffusion, i.e. CRM use, impacts on business processes, and impacts on firm performance. While the literature mainly addresses the forms and contingencies of IT governance structures for decision making, we focus on IT governance mechanisms for decision execution, that is, the role of top management, business managers and IT managers in post-adoption stages of technology diffusion and how these groups are held accountable for their role. We conceptualize decision execution mechanisms of IT governance as including two dimensions: vertical advocacy from top management and horizontal coordination between business and IT managers. Decision execution mechanisms are assumed to facilitate CRM use and value creation. We analyze a dataset of 82 Chinese firms to examine the model and associated hypotheses. Our results show that: (1) decision execution mechanisms, including both vertical advocacy and horizontal coordination, significantly contribute to the three stages of CRM diffusion; (2) vertical advocacy has a notably greater effect on CRM use and firm performance gains than horizontal coordination, which has a greater effect on process gains. (3) CRM use creates operational and strategic benefits in customer-oriented business processes, which further improves firm performance. These findings have important implications for understanding how IT governance shapes the diffusion of CRM technology. 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
