Design And Implementation Of Open-ended Securities Business' Private Clouds Platform Based On Virtualization Technology

Currently,the light business department has become an important mode of rapid expansion of securities companies.We can not only expand the business layout of the securities company,but also enable the rapid expansion of the business by relying on the light of the business department.The information system of the light securities business department needs to have the characteristics of rapid deployment,centralized management,cost saving,safety and stability.The deployment model of traditional business department information system have not meet the needs of modern.How to deploy the light business department quickly becomes an important subject in the information construction of securities companies.This thesis will explore how to use the new technology to build a light business department.We solve the rapid deployment of light business department by introducing a private cloud platform based on virtualization technology.Main contents are as follows:(1)This thesis designs a virtualization technology,which is mainly based on Citrix.Relying on the application of the technology of the delivery of securities private business cloud optimization platform can achieve rapid deployment of the business department,centralized management and mobile office function.The design of this thesis is based on SSL encryption +RSA two factor authentication technology,can meet the relevant rethesisquirements of the securities industry.This security architecture design in the banking sector,the insurance industry and other financial industries to verify,is a safe and reliable architecture design.(2)In this thesis,the private cloud platform based on virtualization technology is designed into two independent centers.Each center of the private cloud platform software,hardware,including storage and network are deployed independently.In order to improve the reliability of the whole system,the global load balancing strategy is used to implement the two centers.Cloud platform can meet the deployment of most application systems,which is flexible and easy to expand.Applications on cloud platforms need to be upgraded or backed up.It can be stored through the platform snapshot function quickly and easily realized.If the back needs to be upgraded,It can be restored immediately.The advantage of the private cloud platform is that it solves the problem of the application of the existing hardware and application compatibility problems of the old system software platform in the industry.For example:some are still on the Windows Server2003 application,and the latest server is no longer supported by this version of the release.(3)Combined with Citrix XenApp,XenDesktop,NetScaler and Citrix ICA(Independent Computing Architecture)and other application virtualization technology,the open private office desktop(WINDOWS7)cloud platform in the securities industry is realized.Through the use of ICA virtual channel technology for high-definition camera scanning process custom development.In this thesis,the process of image preview and uploading in the cloud desktop is separated to ensure the high definition image file transmission in the cloud desktop in the limited bandwidth.(4)In this thesis,on the implementation of the cloud platform,in view of the use of securities,branch business and mobile office use scenarios,carried out a detailed test to ensure that the actual work can be used.After the security application system is installed on the cloud platform,there is no difference between the operation and the original physical platform,and the deployment is more flexible and convenient.After the use of cloud platform,a large number of business can further enhance the user experience.Compared with the traditional VPN mode of remote login,cloud platform is more secure and smooth.For mobile office applications,intelligent mobile phone and tablet computer by APP test(Citrix Reciver)to log into a cloud platform for business operations,can still reach the business effect,basically at any place,any time to demand business.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 and reliable,easy expansion and upgrade,can meet the business needs of securities business department of light,has the reference value for the securities industry to deploy light business department and mobile office application.
