文档介绍：摘要以云计算为代表的IT新技术的快速发展,使得云平台的技术研究成为热点, 使用云平台承载各种大规模的信息服务也成为产业的发展趋势。云计算作为一种崭新的商业模式和计算模式,因其可伸缩性、按需服务、虚拟化、高可靠性等特征给客户带来了各种完美的体验,因此各行各业都在开始利用“云”来解决各种商业或实际应用问题,云计算也随之逐步渗入到行业云的层面。作为最早使用信息系统的证券行业,无论是在计算层面还是在应用层面都位于信息处理领域的领先行列。本文针对选题主要从以下几个方面进行分析:首先对对云计算概念、分类及其特点进行了比较详细的分析,并结合证券行业分析云计算在数据分析、数据存储、证券行情数据挖掘等方面使用的可行性;其次针对传统证券行业通过卫星广播获取行情数据的不足,探讨构建基于互联网获取证券行情数据的方法和技术, 研究基于证券行情的数据接口设计和数据存储技术;接着对金融数据服务平台的架构、平台的各个组成模块,以及基于云计算的相关技术进行比较详细的分析; 最后讨论如何基于Eucalyptus开源平台来架构证券基础信息云服务平台。关键词:云计算;云平台;数据抓取;证券平台 Abstract The greatdevelop ofITnew technology represented by puting made theresearch ofcloudplatform e ahotdomain,and using puting carry various large—scaleinformation service e which as a mercial model puting schema brings perfect experience as its featuresofscalability,service bydemand,virtualization andhigh reliability,SOevery industry or trade begin using”Cloud”to solve mercial problems and actualapplication issues,puting gothrough intoprofessional cloud slowly. As the earliest use ofinformationsystem,Security plays the key role both in application layer andinformation domain. According theseclection Topic,thispaper ismainly analyzed from thefollowing severalaspects:first,we make adetailedanalysis abouttheconcept,classificaiton and characteristic puting,and analyze thefeasibility puting in thesecurities industry ofsecurities data analysis,data storage,stock market data bined with the securities because the inadequate of traditional securities industry which fetch market data via satellitebroadcast,we research themethod andtechnology ofhow togetfinancial market datafrom Intemet, rearching thedesign ontheinterfaceoffetching financial dataand storagetechnology. Then analyze thearchitecture offinancial dataservice platform and theconsist of individual module,and taking more detailed analysis oftherelevant technology based on last we discuss about how to construct acloud puting platform byopenplatform which calledEucalyptus.
