【摘要】 面向服务架构(SOA)承诺可以消除企业信息化孤岛,为信息系统带来更多的弹性。但在国内商业银行实际使用中,出现了传统组织运维中的竖井效应,即银行运维仍按部门、条线进行垂直分工,阻碍了SOA发挥原有的效力。业内关注于SOA的设计主要在于开发方面,缺少对于传统运维模式同SOA固有特点之间冲突的研究,特别是针对如何运维SOA下的信息系统的研究尚属于起步阶段。本研究首先从SOA的特点开始探讨,分析SOA三大特点对日常运维的挑战,特别是对于商业银行集中式运维模式的冲突。然后根据这个冲突,指出原有集中维护模式已不能适应SOA的运维,提出寻找新的运维流程和框架的想法,提出了面向SOA治理的想法。然后,根据商业银行生产环境的现实情况,论文参考软件能力成熟度,提出了SOA治理成熟度模型,通过五层的成熟度模型,定性模拟了不同企业面对SOA运维所处的阶段。论文选择信息系统基础设施库(ITIL,Information Technology Infrastructure Library)作为帮助企业提升成熟度的工具。论文充分利用ITIL作为最佳实践在传统运维领域的优势,采取逐流程分步实施的方法,每个成熟度阶段都实施两到三个流程,确保在风险可控的前提下,最终完成针对SOA环境的可量化、可控制的运维管理系统。最后,本文所描述的模型和实施方法,在中国民生银行已经实际使用2年,通过实际工作验证了这个模型贴近商业银行现实情况,也证明了本文提出了通过实施ITIL来运维SOA环境的方式是有效可靠的。更多还原

【Abstract】 SOA promises to eliminate information isolation in an enterprise and provides more elasticity for an informative system. However, the application/deployment of SOA in China’s commercial banks has encountered the so-called“maintenance silo”problem, i.e. vertically specialization of labor as per departments and function lines in commercial bank daily operation and maintenance, which significantly reduces SOA’s effectiveness. Since domestic effort on SOA focuses more on the development side, it lacks the conflict research among SOA characters with traditional operation. In particular, the study on SOA operation and maintenance remains at its infant stage.Firstly, this paper starting from the discussion about SOA three characters is to analysis the challenging those SOA characters facing to daily operation/management, especially conflicts to centralization operational method in commercial bank. Then it points out the original centralization maintenance method is not suitable, and requires to find out new thoughts in operational process and framework. As such, it presents ideas in SOA governance.Secondly, on the basis of real situation in commercial bank, this paper takes reference from software maturity to propose a framework of SOA governance maturity. Five maturity model define and measure different levels that different enterprises sits in SOA operation/management. It chooses ITIL (Information Technology Infrastructure Library)as a tool to promote governance maturity. And by taking advantage of strength in ITIL, it phases in implementation steps. Each phrase binds with two or three processes that ensure the operation/management system is measurable and under control with limited risks for SOA governance.Finally, Field test in CMBC has been running for two years and it shows that our framework and roadmap is workable and effective. By means of work practice, it testifies this framework is catering for commercial bank and also proves the reliability by implementing ITIL practice to promote SOA governance maturity更多还原
