|Location Intelligence Module / Architecture Overview|
The diagram below shows an example of the default, initial architecture of Spectrum™ Technology Platform Location Intelligence Module, where there is a single server on which Spectrum Spatial is installed. Everything, including the repository, image files, and tile cache on a single box in the same location as where the product is installed.
To scale Spectrum Spatial from one to three servers, each server leverages a single shared database server and image server to maximize efficiency and to avoid situations where an image or database resource is unavailable to one of the Spectrum Spatial servers. The file image server stores all images between multiple versions of Spectrum Spatial. All instances of Spectrum Spatial store images in a single location
