云桌面,湖北中烟绿色IT的基石

云桌面管理系统是基于服务器虚拟化和云计算理念成长起来的终端管理方法,它完全颠覆了传统意义上的终端管理概念。它的出现使得网络管理人员不必再将维护的重点放在分散的个人终端上,只要维护和加固服务器端便可以实现全网络终端便捷的维护和高安全。用户也可以从选择和安装各种安全软件、补丁升级、病毒库升级等繁杂的个人维护工作中解脱出来,从根本上避免系统瘫痪、软件冲突及误操作等多层面的问题。云桌面管理系统完全不同于传统模式的终端管理软件,集中化和虚拟化的特点不仅仅会大大增强内部系统及网络的安全性,同时也因此减少了网络运维的复杂程度和运维成本。为顺应行业信息化发展潮流,问道信息公司以自身为蓝本,结合湖北中烟企业信息化现状,秉承勇于探索精神,通过引入云桌面架构,实现技术管理创新,力图拓展业务发布方式,扩大用户终端的接入手段,为日后湖北中烟终端用户提供稳固、安全、可靠、便捷、一致的业务访问服务提供技术积累。     

经济日报数据中心X86服务器虚拟化综述

在著名的市场调研机构Gartner做出的2010年和2011年十大策略性科技排行榜中,虚拟化技术和云计算连续两年都榜上有名,这两年里我们也确实可以看到VMware、Google、Oracle、微软等相关行业巨头都投入了大量的资源来发展和推广虚拟化技术和云计算。云计算的目的就是要逐步将符合条件的IT服务全部部署在公有云和企业私有云上形成云资源池,以提供具有弹性的、可度量的、用户可按需使用的自助式服务,然而相对于需求多样、博弈复杂、标准未定的公有云计算,具有足够计算资源和内部服务需求的企业私有云计算更容易落地,而虚拟化技术正是云计算的基础。此时又恰逢低碳时代,作为企业碳排放主力的数据中心无疑也要与时俱进。由于服务器虚拟化技术具有提高服务器计算效率的内在特点,通过实施服务器虚拟化可以大幅度提高数据中心X86服务器的使用效率,从而减少物理服务器数量,降低数据中心能耗,客观上也可以增加企业经济效益。虚拟化技术已经从几年前人们谈论的"发展趋势"、"数据中心的未来"等未来时发展成了企业当下建设、改造数据中心以及实施企业私有云计算的基础技术。目前VMware是企业虚拟化技术领域的开拓者和领跑者。服务器虚拟化除了具有低碳和相对降低数据中心运维成本的优势外,VMware虚拟化技术旗舰产品的vSphere还是一个完备的数据中心解决方案,它所构建的虚拟数据中心具有HA、DRS等高级功能,可以为企业创建一个永不宕机的计算环境,同时其所提供的IT资源的管理功能也可大大提高企业数据中心的管理能力和效率。在这个大背景下,经济日报集团在其新闻采编信息系统建设项目设计和实施过程中,采用VMware的vSphere 4.0系统软件将数据中心建设新信息系统所新增加的X86服务器进行虚拟化。
