摘要: A spatial web portal (SWP) provides a web-based gateway to discover, access, manage, and integrate worldwide geospatial resources through the Internet has access characteristics of regional global interest spiking. Although various technologies have been adopted improve SWP performance, enabling high-speed resource for users better support Digital Earth remains challenging because computing communication intensities in operation dynamic distribution end users. This paper proposes cloud-enabled framework by leveraging elastic pooling, workload balancing, deployment. Experimental results demonstrate that new outperforms traditional infrastructure supports system such as Earth. Reported methodologies can be operational systems, monitoring national geographic state sp...
