Ubuntu: the leading linux-based operating system


Ubuntu is an open source linux-based operating system. It is developed by Canonical and a community of developers — under a meritocratic governance model.  It was launched in October 2004 and it is composed mainly of free, open source software. This Linux distribution, based on Debian’s architecture and infrastructure, is widely popular among cloud computing projects.

A new non-LTS version is released every 6 months and a LTS (long-term support) version is released every 2 years. Canonical provides security updates and support from the release date to the End of Life (EOL) date. LTS releases are supported for 5 years and non-LTS releases are supported for 9 months.
