Ubuntu Technology Intelligence

What is Ubuntu?

Ubuntu is the world's most popular Linux distribution for servers, desktops, and cloud deployments. Developed by Canonical since 2004, Ubuntu's name means "humanity to others" in Zulu. It provides a free, stable, and user-friendly operating system with commercial support options.

Ubuntu dominates the cloud and server market, running on over 50% of cloud workloads. AWS, Azure, and Google Cloud offer Ubuntu as a primary option. It's the reference platform for OpenStack, Kubernetes, and countless DevOps tools.

With Long Term Support (LTS) releases every two years receiving 5-10 years of updates, Ubuntu provides enterprise stability. Ubuntu 22.04 LTS is supported until 2032 with Ubuntu Pro. The distribution balances cutting-edge software with production reliability.
