中文摘要：

传统WMS服务基于集中或者离散分布B/S模式,单台服务器既要承担地图发布的任务,也要承担地图绘制的任务,当大量客户端并发访问服务器时,服务器响应速度明显降低甚至宕机。针对传统WMS服务模式的不足,将WMS服务构建于自主开发的云平台之上,详细阐述了实现的关键技术,包括WMS云服务框架的设计、空间数据的组织方法和任务调度策略。并且对B/S模式和云模式下的WMS服务性能进行了测试,证明了在同等服务器硬件环境下,云模式的WMS服务具有相对较高的处理效率,其研究具有十分重要的实践应用价值。

英文摘要：

The traditional WMS is based on the mode of B/S, which means the server is necessary to assume the task of publishing the map and the task of mapping.When the connected clients＇ number is too high, the server re- sponse speed reduces and even paralyzes.To overcome the shortcomings of the traditional mode, WMS is built on the cloud platform which is developed by the author.The key technologies are proposed in this paper, including the design of cloud WMS framework, the organization of the spatial data, and the dispatching of the WMS tasks on the cloud platform.The B/S model and the cloud model of WMS are tested to prove that the server of WMS under the cloud framework has more processing power.The study has important theoretical significance and practical value.
