ArcGIS Server分布式技术实现与优化

为了解决硬件资源难以满足WebGIS信息增长的需求,提出了ArcGIS Server分布式技术实现企业级GIS应用程序的综合平台.使用WebService技术,在业务逻辑层和空间信息层加入分布式处理服务器,能够真正实现WebGIS系统逻辑上和物理上的分布式处理服务.采用Web Service技术和ArcServer技术可以将信息量巨大的WebGIS系统分解成多个Web Service的分布式服务,从而解决硬件资源上的问题,同时对ArcGIS Server的性能进行最小的服务器资源占用率、最小化的数据传输量、最合适的图像格式和最佳的代码执行效率的优化,提升整个系统的性能.

Realization and optimization of ArcGIS server distibuted technology

To solve the hardware hardly satisfies the growth WebGIS informations,a comprehensive platform technology for enterprise-level GIS applications based on ArcGIS server web service is proposed.Web Service is a new generation of service-oriented distributed computing model.Web Service,by using the Web Service server between the business logical and spatial information layer,can substantially realize the logical and physical distributive processing server in the WebGIS system.Using the technique of Web Service and ArcGIS Server can resolve the amount of WebGIS information problem by distributing several Web Services service,and also resolve the problem of hardware.At the same time,the ArcGIS Server performance of minimal server resources occupancy rate,minimizing the amount of data transmission,the most suitable image format and the best advantage of the efficiency of code execution are optimized to get the optimal system performance,hardware.
