During Ubuntu Live in Portland, Canonical (the Ubuntu main sponsor) announced the availability of Landscape a tool for Canonical support customers.
This tool was designed to manage your IT infrastructure: all your servers/desktops/laptops are configurable through a web interface. The web interface also permit to get an inventory (hardware and software), to monitor them, etc. For a complete (and better) description visit the presentation page on Canonical website.
This tool appears to be the dreamed tool for the sysadmin I am. I have to confess that we have started a super-secret project for a similar tool. Well, that’s said, I also have to confess that landscape looks better than our tool right now…
