Ubuntu
The vision for Ubuntu is part social and part economic: free software, available to everybody on the same terms, and funded through a portfolio of services provided by Canonical.
Ubuntu today has nine flavours and dozens of localised and specialised derivatives. There are also special editions for servers, OpenStack clouds, and mobile devices. All editions share common infrastructure and software, making Ubuntu a unique single platform that scales from consumer electronics to the desktop and up into the cloud for enterprise computing.
