Informatique, Financière agricole du Québec, Canada
Since 2000 we have been using Debian servers for geomatic software (ESRI, mapserver, cartoweb), Internet (TYPO3), security, development (apache, php), printing (CUPS), mail (SpamAssassin, amavis, clamav), file sharing (Samba), secured file transfer, databases (Oracle, MySQL), etc.
We chose Debian for its stability, security handling and the package management system.
