【摘要】：在云计算迅速升温的大环境下,构建更为强大的数据中心已经成为IT业界的风向标。以互联网业界巨头们为例,谷歌、亚马逊、微软已从传统软件产品开发供应商,悄然转变为信息化服务应用提供商,这些角色的转变也预示着云计算服务必将在不久的未来全面取代传统信息化模式。放眼我国互联网的企业,阿里、腾讯也积极的参与到云服务数据中心建设和标准制定,由此可见,不仅仅是国外,本土的IT业界已将其视为未来十年乃至更长时间IT业的发展的重要方向之一。本文以AVQ公司及其现有信息系统为实例背景,论述公司实施云计算的信息系统架构方案。首先分析AVQ公司现有的信息系统架构和业务背景,发现现有信息系统架构存在系统反应不敏捷、信息不对称性和数据不统一等问题以及系统扩展性差、成本难以控制等约束。以解决制约公司业务发展和管理问题为目标提出引入云计算必要性。然后运用SWOT方法针对AVQ公司实施云服务战略的内外环境进行全面分析,围绕优势、劣势、机会和挑战四个纬度的分析提出将战略、战术、技术和特征作为AVQ公司实现云服务需求的立足点。提出将云计算的三大服务模型(SaaS/PaaS/IaaS)引入作为AVQ公司实现信息系统架构改造的总体框架思路。随后围绕AVQ公司云计算体系下的具体架构设计和解决方案展开,从云服务商和技术方案的选定,到云服务和IT管理学的结合,再到架构方案和业务及资源的转换的论述,结合对云计算的三大服务模型在不同程度下执行阶段式验证,即:利用SaaS实现AVQ公司产品到服务的转型、利用PaaS为AVQ公司业务提供开发和应用分发接口、利用IaaS实现AVQ各级基础设施资源的整合和共享,为最终实现系统完善、业务转型、成本可控、资源共享以及科技跟随到引领的转变。最后,提出基于云计算的信息系统实施评价体系,并对论文提出的实施方案进行效果评估。结果表明依托云计算科学实施AVQ公司云服务战略,将有效扩大高科技软件企业的市场规模,提升行业地位,达成业务目标。本文的研究是对企业级云计算理论到实施的扩展。
[Abstract]:In the rapid warming of cloud computing environment, the construction of a more powerful data center has become the IT industry vane. Take the Internet giants as an example. Google, Amazon and Microsoft have quietly transformed themselves from traditional software product development providers to information service providers. The transformation of these roles also indicates that cloud computing services will completely replace the traditional information mode in the near future. Looking at the Internet enterprises in China, Ali and Tencent are also actively involved in the construction of cloud service data centers and the establishment of standards. This shows that it is not just foreign countries. Local IT industry has regarded it as one of the important directions of IT industry development in the next decade or more. Taking AVQ Company and its existing information system as an example, this paper discusses the implementation of cloud computing information system architecture. Firstly, the existing information system architecture and business background of AVQ Company are analyzed. It is found that the existing information system architecture has some constraints, such as unagile system response, information asymmetry and data disunity, poor system expansibility and difficult cost control. Aiming at solving the problem of restricting the business development and management of the company, the necessity of introducing cloud computing is put forward. Then using the SWOT method to carry out a comprehensive analysis of the internal and external environment of the cloud service strategy implemented by AVQ Company, and put forward the strategy, tactics around the four latitudes of strengths, weaknesses, opportunities and challenges. Technology and features serve as a foothold for AVQ to meet cloud service requirements. Three service models of cloud computing, SaaS / PaaSr IaaSs, are introduced as the overall framework of AVQ to realize the transformation of information system architecture. Then it focuses on the specific architecture design and solution under the cloud computing system of AVQ, from the selection of cloud service providers and technical solutions, to the combination of cloud services and IT management, and to the discussion of the transformation of architecture, business and resources. Combined with the three service models of cloud computing, we implement phase verification in varying degrees, that is, we use SaaS to realize the transformation of AVQ products to services, and use PaaS to provide development and application distribution interfaces for the business of AVQ. IaaS is used to realize the integration and sharing of infrastructure resources at all levels of AVQ. In order to realize the system perfection, business transformation, cost control, resource sharing and technology follow the leading change. Finally, the implementation evaluation system of information system based on cloud computing is put forward, and the effect of the implementation scheme proposed in this paper is evaluated. The results show that relying on cloud computing science to implement cloud service strategy of AVQ company will effectively expand the market size of high-tech software enterprises, enhance the status of the industry, and achieve business objectives. The research of this paper is an extension of enterprise cloud computing theory to implementation.
