You can architect your Dekho installation to use parts of your organization's existing IT infrastructure. In the diagram below, the Web Adaptor has been offloaded to a web server on a separate machine. Similarly, the data, server directories, configuration store and Dekho folders have been put on a dedicated data server.
In this scenario:
§ Dekho deployed under Tomcat on GIS Server. Alternatively, you can deploy the Dekho application separately under another tomcat instance on the Web Server.
§ Add map/image servers to Server Catalog in Dekho Admin making sure to use the web. This will make use of all GIS servers within your ArcGIS Server site for map requests.
