ESRI and IBM hosted an Enterprise GIS Special Interest Group (SIG) meeting this morning that explored hot topics in enterprise architecture including cloud computing, performance, and security. Doug Tidwell of IBM gave a particularly clear description of cloud computing while ESRI's Michael Young shared ESRI research to improve enterprise performance, security, and virtual environment support.

ESRI has launched the Enterprise GIS Resource Center to address patterns and best practices in these and other enterprise architecture areas. The presentations from this morning will be posted to the resource center.
