基于云平台的地理信息公共平台部署与测试

地理信息公共平台是“数字城市”建设的基础部分，面向政府部门、企业及个人，提供着全方位的地理信息在线服务。云计算作为一种新兴技术，利用其资源动态伸缩，自动监控，分布式存储，使得用户群体自订制IT基础设施资源成为可能。广东省地理信息公共平台通过试验依托云平台组建服务器集群，实现了高可配、高性能，为下一步平台全面使用云计算的升级奠定了基础。

Implementation and Evaluation of Public GIS Platform Based on Cloud Technology

Public GIS Platform is the fundamental part of the ＂Digital City＂, which provides comprehensive online geograph- ic information services to government departments, enterprises and individuals. As a novel event, cloud computing drives some technologies like the source dynamic stretching, auto monitor- ing, distributed storaging, client customizing instruction and so on become possible. In this paper, public Guangdong GIS plat- form is implemented in the structure based on cloud computing via servers clusters, thus achieves highly adaption and perfor- mance, which gives valuable experiences for upgrading the platform in future.
