IT, Intelligent Applications Sweden AB, Sweden
Intelligent Applications Sweden AB use Debian on some of its application servers, routers, test systems, and developer workstations.
Software developed to run on the servers is packaged in Debian's native .DEB format and rolled out using APT. Typical software used in conjunction with software developed in-house is: apache, freeradius, gcj, mysql, perl, php, postgresql, tomcat, etc.
Debian was chosen because of the overall quality of the distribution, in-house Debian competence, maintainability, the social contract, sane defaults, and last but not least the superior packaging system and the vast amount of pre-packaged software for it.
