【摘要】：当前,轻型营业部日益成为证券公司快速扩张分支机构的重要模式,依托轻型营业部不但可以扩张证券公司的营业版图,更能使得各业务迅速进行延伸。而轻型证券营业部的信息系统需要具备快速部署、集中管理、成本节约、安全稳定等特点,传统营业部信息系统部署模式已不符合现代需求。如何快速部署轻型营业部成为证券公司信息化建设方向的一个重要课题,本文探讨如何用新技术来构建轻型营业部,通过引入基于虚拟化技术的私有云平台解决轻型营业部的快速部署的方案。论文的主要工作包括:(1)设计了一种使用虚拟化(主要以Citrix的应用虚拟化技术)及应用交付技术的证券开放式业务私有云优化平台,依托该平台,可以实现营业部的快速部署,以及集中管理,同时提供移动办公功能;该平台的远程接入安全,本文设计是基于SSL加密+RSA双因素认证技术,可以达到证券业行业的相关需求。这样的安全架构设计在银行业、保险业及其它金融业中得以验证,是一种安全可靠的架构设计。(2)将基于虚拟化技术的私有云平台设计成两个独立的中心分别进行工作,每个中心的私有云平台软、硬件包括存贮和网络均独立部署,并采用全局负载均衡策略实现两个中心的协同运行,以提高整个系统的可靠性;云平台可以满足目前大多数应用系统的部署,该架构灵活方便、便于扩容。云平台上的应用需要升级或备份,只要通过平台中的存储快照功能就能很快很方便的实现。如果升级需要回退,通过快照可立即恢复。私有云平台的优势在于,其解决了目前不断升级的硬件与行业中旧系统软件平台的应用兼容性问题;比如:有些至今仍在Windows Server2003上的应用,而最新的服务器已经不再支持这一个淘汰版本。(3)结合 Citrix 的 XenApp、XenDesktop、NetScaler 以及 Citrix 的 ICA(Independent Computing Architecture)等应用虚拟化技术,对证券行业开放式业务私有办公桌面(WINDOWS7)云平台进行了实现;通过使用ICA虚拟通道技术对高清拍摄仪扫描过程进行定制开发,实现了在云桌面中图像预览和上传过程的分离,以保证有限带宽条件下在云桌面中可以实时进行高清图像文件传输。(4)本文在所实现的云平台上,针对证券应用、分支机构业务以及移动办公等使用场景,进行了详实的测试,以确保在实际工作中能够正常使用。证券应用系统在云平台上安装好后,在操作上和原先的物理平台上使用没有任何区别,而且部署实施更灵活方便。大量业务通过云平台使用后,可进一步提高用户的体验,和传统VPN方式的远程登录相比,更加安全、更加流畅。针对移动办公应用,主要测试了智能手机和平板电脑通过APP(Citrix Reciver)来登入云平台进行业务操作,依然能够达到业务使用效果,基本实现了在任何地点,任何时间都可以进行业务办理的需求。本文所实现的基于虚拟化及应用交付技术的证券开放式业务私有云平台已经成功应用,应用效果表明,该平台安全、可靠、方便扩容和升级,可满足轻型营业部证券业务需求,对证券行业部署轻型营业部及移动办公应用具有参考价值。
[Abstract]:At present, the light business has become an important branch of rapid expansion of the securities company, relying on sales of light can not only expand the securities company business layout, more rapid extension of the business. And the information system of the light of the securities business department requires rapid deployment, centralized management, cost saving, safety and stability etc. The characteristics, the traditional business information system deployment mode has not meet modern needs. An important topic how to quickly deploy light business department to become the direction of information construction of securities companies, this paper discusses how to use new technology to build the business department of light in this paper, through the introduction of private cloud platform based on virtualization technology to solve the fast light business department Quick deployment plan. The main work includes: (1) design a virtualization (mainly the application of virtualization technology Citrix) and application delivery technology of open securities business private cloud optimization platform, relying on the platform, can achieve rapid deployment of business department, and centralized management, while providing mobile the flat office functions; Secure remote access platform, this paper design is SSL +RSA encryption technology based on two factor authentication, can achieve the requirements related to securities industry. This security architecture design in banking, insurance and other financial industry can be verified, is a safe and reliable design architecture. (2) based on the private cloud platform design a virtualization Technology Two independent work center respectively, private cloud platform each center is soft, the hardware including storage and network are deployed independently, and the global implementation of collaborative operation of two center load balancing strategy, in order to improve the reliability of the whole system; cloud platform can meet most application system deployment, the architecture is flexible and convenient, To facilitate the expansion. Cloud platform applications need to upgrade or backup, as long as through the snapshot storage function can quickly achieve the platform very convenient. If the fallback need to be upgraded by the snapshot can be restored immediately. In the private cloud platform, which solves the old system software platform and hardware currently upgrading in the industry application and For example: some compatibility problems; since the application is still in Windows Server2003, and the new server is no longer supported this one out version. (3) with Citrix XenApp, XenDesktop, NetScaler and Citrix ICA (Independent Computing Architecture) should use virtualization technology, open private business of the securities industry The desktop (WINDOWS7) cloud platform is realized; by using ICA virtual channel technology of HD shooting instrument scanning process of custom development, to achieve the separation of image preview and upload process in cloud desktop, high-definition image file transmission to ensure that under the condition of limited bandwidth can be realized in the cloud desktop (4) in this paper. In the implementation of The cloud platform, in view of the stock application, branch business and mobile office usage scenarios, detailed testing, to ensure the normal use in practical work. The securities application system in the cloud platform after installation in the operation and the original physical platform to use no difference, and the deployment of more flexible A large number of business. Through the cloud platform, can further improve the user experience, compared to the traditional VPN mode remote login and more secure, more smooth. For mobile office applications, intelligent mobile phone and tablet computer by APP test (Citrix Reciver) to get into the cloud platform for business operations, can still achieve business the In effect, the basic realization of in any place, any time can handle business needs. The implementation is based on virtualization technology and application delivery security open service private cloud platform has been successfully applied, the result of application shows that the platform is safe, reliable, easy expansion and upgrade, which can meet the securities business department of light industry The service demand, has the reference value to the securities business department of light industry deployment and mobile office applications.
