甲骨文刘松-从全球统一系统到企业云课件.ppt

日程 优化前的挑战 优化的过程 多个层面的整合 提供内外云服务 基础设施优化的五个技术关键点 挑战与经验 2000-2008 整合时间表 2000年：70个ERP系统 2001年1月：缩减为20个ERP系统 2002年1月：缩减为10个ERP系统 2003年1月：缩减为3个区域ERP系统 2004年1月：完成全球1个ERP Instance 2004-2008年：每年节省15亿美金的成本 2006年：实施全球CRM系统，统一前台业务管理 27000 使用者，12000个合作伙伴 2007年：实施全球商业智能与绩效管理系统 2008年：完成ERP, CRM，企业级商业智能的一体化 经验与对策 体制的阻力：重视因变化对员工带来的冲击 明确的目标：支撑全球化，收购，安全管控 统一的流程：采用统一版本的应用系统来规范流程 专门的组织：有经验的专门团队 严格的执行：不执行的实体不发工资 量化的收益：事先事后的IT财务指标 渐进的执行：国家-区域-全球模式 低成本设施：Linux+Intel+虚拟化，数据中心选择 * * * * * This data applies to our Intel x86/x64 Farm. This Farm is used by engineering for the development of Database, Fusion Middleware, and Enterprise Manager products on Linux (OEL, RHAT,Suse) 32 and 64, Windows (XP, 7, Server 2003, Server 2008, Vista) 32 and 64, and Solaris on Intel 64. We also have a variety of configurations (e.g. 2-node clusters, 4-node clusters, 8GB of Memory systems, 4GB of Memory systems, etc.).We have ~6,000 virtual servers across ~2,600 physical servers.The Farm is used by over ~3,500? developers.For the Linux OEL4 32, which is the biggest portion of the Farm being LINUX our base dev environment, we are able to process over? 70K hours per day. This translates into over 45,000 jobs processed. jobs are either execution of product builds or product tests. These test run for an average of close to ~2 hrs.The utilization rate of these serves is about 80% over 7 days a week. Monday through Friday by the way is almost 100%? as people take a break over the weekend :) .The benefits have been the following:- A significant boost in development productivity. A developers could simply not do what hes able to do now without the Farm. It is self-service system when developers simply need to push a button to submit their jobs.- Cleaner code lines as code is thoroughly tested before being committed to the product.- Speed of development has been increased.This whole system provides us (i.e. Oracle Development) a significant competitive advantage over other software shops. Thats why I h
