Building a High-Availability ArcIMS Hosting Infrastructure for NYC
Track: System Implementation for GIS
Author(s): Mario Gouvea

New York City's Department of Information Technology and Telecommunications (DoITT) hosts a variety of e-government web based applications to serve the public, some of those are ArcIMS applications that DoITT hosts for city agencies: My Neighborhood, My Neighborhood Statistics and EMOLs. Due to the increasing demand for an ArcIMS hosting infrastructure for New York City agencies and the need for a robust environment to host emergency applications, DoITT ventured in upgrading its aging equipment and moving it in-house. The result is a 24x7 scalable environment consisting of more than 25 Sun Microsystems servers, 10 of which are in production and the remaining are part of the development, test, staging and disaster recovery environments. This paper describes the process of designing a high-availability ArcIMS hosting infrastructure for New York City starting from the architecture design to the sizing of servers, integration, configuration, and the deployment of applications with zero downtime.
