The Systenm Upgrade Program Of Financial Information Database Based On Cloud Computing

In recent years,cloud computing or cloud-based technology is a computer application and research in the field of a hot technology,most businesses have their products marked with a tag cloud and core architecture as the third computer platforms,cloud computing,and cloud-based application and promotion of network computing technology,making all network resources around the world sharing,such as computing resources,storage resources,network resources.In a significant cloud computing applications,more powerful computing resources and a huge storage capacity been recognized,applied and many resources are not required costly software and hardware costs,and computing resources needed for these customers and calculations cloud service providers have to provide customers and management.Thus,the end customers of cloud computing can save a lot of costs,the development of cloud computing has prompted a growing number of enterprise network cloud platform shift.In this paper,cloud computing technology is technology,combined with distributed storage database system,SAN storage systems and virtual networks to upgrade existing systems.And introduced its cloud computing service model,key techniques related to distributed database systems,virtualization technology and cloud storage technology and system upgrade program carried out exploration and research.This article focuses on the following research areas:1)Analysis of cloud computing technology,distributed database technology and virtualization technology,combined with existing systems upgrade program of the cloud.On this basis,business needs analysis and comparison of existing financial information database system upgrade requirements and future expansion and maintenance for research and comparative apply to this system technology.Provide a theoretical basis for the subsequent build a complete system upgrade program.2)Demonstrate the feasibility aspects of the upgrade program,the demand for system upgrade scenarios,business analysis systems and system upgrade with a needs analysis example of the system upgrade program for research.Clear the system upgrade three major aspects:upgrade,upgrade the storage system and a physical machine virtualization database system upgrade.Detailed analysis of these three blocks of upgrade requirements,including system architecture,simple model programs and preliminary program recommendations.3)Based on the research needs of the system upgrade program.according to the principles and objectives of the system design gives the cloud platform infrastructure system.Respectively,for the three most needs detailed design.Database upgrades for the study of distributed database system backup to ensure data integrity and proper migration row;and the introduction of a dynamic load balancing algorithm based on feedback,the system upgrade program to ensure reasonable during database system built in sex.For storage system upgrade,the system intends to use SAN storage system,and a plurality of heterogeneous database systems for data integration,and tiered storage system data,thereby improving the performance of the data processing system.For physical aspects want to migrate a virtual machine,the system main virtualization technologies and solutions based on VmWare family of software designed to host virtualization,storage virtualization,network virtualization.Finally,through the design of the experimental program to upgrade the feasibility of the construction aspects of a strong argument.
