We use two Debian servers to store our applications and all kinds of work files. On the servers we have installed Apache, MySQL, Samba, Gallery for photos, and a FTP server. Also, we have three terminals with Debian, office utilities, and with access to the management system installed on the servers.
We decided to use Debian because of its stability, robustness and also by recommendation of people we trust. It did not seem difficult to us to use this distribution. Previously we used operating systems and programs from MS, but the high cost of licenses, added to the instability and insecurity, made it easy for us to decide to use Linux.
