What Is Linux? Distributions and Server Selection

Originally published: 2024-05-13

Technical review: 22 October 2026

Linux is a kernel. Distributions such as Ubuntu and Debian combine it with system tools, a package manager and other components. A server deployment therefore requires a suitable, supported distribution rather than a kernel download alone.

Who develops Linux?

Linus Torvalds started the Linux kernel, with many contributors and organisations involved in its development. See kernel.org's explanation of kernels and distributions.

Choose around the workload

• Check security support and the upgrade path.
• Confirm compatibility with the control panel, database and application runtime.
• Verify backup, recovery and monitoring tool support.
• Consider your team's operational experience and support needs.

Do not base a decision on distribution market shares without a defined source and measurement scope. Open source does not eliminate vulnerabilities or the need for updates, access controls and backups. Free distribution downloads also do not remove operating and support costs.

Hosting or a Linux server?

Web hosting may suit a standard site. Compare virtual server rental options for custom services, runtimes or administrator access. Projects requiring separate physical hardware can evaluate a dedicated server, including its management and licence scope.
