Crime Insight is typically deployed in a two server configuration. While it is possible to further separate out components across multiple servers, it is not recommended as the performance gains rarely justify the increased complexity around the security requirements. 


The front-end server is used to host all the customer/Internet facing user interfaces. One or more web sites and applications will be installed into Microsoft Internet Information Services web server. Virtual machines are supported.
 
The back-end server also hosts several websites and applications; however, these are never accessible to users directly, but instead are web services that accept data ingestion for information being processed into the Crime Insight databases. Typically the installation of the application component on the back end prevents installation on shared SQL servers. Virtual machines are supported, but administrators should be aware that a nightly processing job incurs a tremendous amount of disk activity, so when virtualized the back-end server can create some contention for disk on the host.
 
Requirements for each are presented in the following sections.
