Ubuntu

What Is Ubuntu?

In 2004, Mark Shuttleworth — a South African-British entrepreneur who had made his fortune selling digital certificates and then bought himself a ticket to the International Space Station — decided to solve a problem that had frustrated him for years: Linux was powerful, but it was not accessible. The distributions available at the time required technical knowledge to install, configure, and maintain. Shuttleworth wanted Linux for everyone. He called it Ubuntu, a Zulu word meaning "humanity to others," and he funded it through a new company called Canonical, headquartered in London.

Two decades later, Ubuntu has become something its founder could not have fully anticipated: infrastructure. It is the default operating system for cloud workloads, powering over 40% of instances on AWS, Azure, and Google Cloud. It is the most popular Linux distribution for containers and Kubernetes. It runs on the International Space Station, on NASA's Ingenuity Mars helicopter, and in Tesla's manufacturing systems. The desktop version — the original product — remains the most widely used Linux desktop in the world, though desktop market share is dwarfed by the server and cloud footprint.

Canonical, the company behind Ubuntu, employs over 1,000 people and generates revenue through Ubuntu Pro subscriptions, enterprise support, and consulting services. The core operating system remains free and open source. The business model is straightforward: the software is free; the support, security maintenance, and compliance tooling are paid.

Ubuntu releases new versions every six months, with Long Term Support (LTS) releases every two years. LTS releases receive five years of standard security updates, extendable to ten years through Ubuntu Pro. The current LTS release is Ubuntu 24.04, codenamed Noble Numbat.

Key Features

Desktop Experience

Ubuntu Desktop ships with the GNOME desktop environment, providing a clean, modern interface with a taskbar, application launcher, virtual desktops, and a notification system. The GNOME experience on Ubuntu is customised with Canonical's own extensions and theming, giving it a distinctive look while maintaining GNOME's usability.

The Software Centre provides a graphical interface for installing applications, ranging from productivity tools (LibreOffice, Thunderbird) to development tools (VS Code, Docker) to media applications (VLC, GIMP, Blender). The Snap package format — Canonical's containerised application distribution system — provides sandboxed applications with automatic updates.

For users coming from Windows or macOS, the adjustment is real but manageable. Basic tasks — web browsing, email, document editing, media consumption — work out of the box. The learning curve steepens for system configuration, driver management, and troubleshooting hardware compatibility. Ubuntu has improved dramatically in this regard over the past decade, but it is not yet plug-and-play for all hardware configurations.

Server and Cloud

Ubuntu Server is a minimal, headless distribution optimised for deployment on physical servers, virtual machines, and cloud instances. It is the most popular operating system on all three major public clouds (AWS, Azure, Google Cloud) and the default image on most cloud providers.

The server edition includes tools for container management (Docker, LXD), Kubernetes (MicroK8s), configuration management (Juju), and infrastructure automation. For DevOps teams, Ubuntu's ecosystem of tools and its dominance in cloud environments make it the path of least resistance.

Ubuntu's position in cloud computing is self-reinforcing: because most cloud workloads run Ubuntu, most documentation, tutorials, and stack configurations assume Ubuntu. This creates an ecosystem advantage that competing distributions struggle to match.

Ubuntu Pro

Ubuntu Pro extends security maintenance from 5 years to 10 years and adds kernel livepatching (applying security patches without rebooting), FIPS 140-2 certified cryptographic modules, CIS benchmark hardening, and expanded security coverage for the entire Ubuntu universe repository (over 30,000 additional packages).

For personal use, Ubuntu Pro is free on up to 5 machines. For commercial use, pricing starts at USD 25 per machine per year for desktops and USD 500 per year for servers. This pricing is competitive with Red Hat Enterprise Linux and SUSE Linux Enterprise, both of which require paid subscriptions for comparable security maintenance.

Snap Packages

Snap is Canonical's containerised application format. Snaps bundle an application with its dependencies, run in a sandbox, and update automatically. The Snap Store provides a centralised repository of applications across distributions.

Snap is Ubuntu's most controversial feature. Supporters value the security isolation, automatic updates, and cross-distribution compatibility. Critics point to slower startup times compared to native packages, larger disk usage, and the fact that the Snap Store is proprietary — a closed-source component in an otherwise open-source ecosystem. The debate is ongoing and genuinely represents different priorities within the Linux community.

Development Platform

Ubuntu is the most popular Linux distribution among developers. It supports every major programming language, framework, and development tool. Windows Subsystem for Linux (WSL) — which runs Ubuntu inside Windows — has further cemented Ubuntu's position as the default Linux development environment, even for developers who use Windows as their primary desktop.

Pricing

Ubuntu is free. The desktop edition, server edition, and all community packages are available at no cost, with no licence fees, no per-seat pricing, and no feature restrictions.

Ubuntu Pro (Personal) is free for up to 5 machines, adding 10-year security maintenance and expanded security coverage. This is a genuine free offering, not a time-limited trial.

Ubuntu Pro (Commercial) starts at USD 25 per desktop per year or USD 500 per server per year, adding enterprise support, kernel livepatching, FIPS modules, and phone/ticket support.

For comparison: Windows 11 Pro costs approximately USD 200 per licence. macOS requires Apple hardware (starting at USD 999). Red Hat Enterprise Linux subscriptions start at USD 349 per year. Ubuntu's price-to-capability ratio is unmatched in the operating system market.

The total cost of ownership calculation is nuanced, however. Free software is not free if it requires significant time for configuration, troubleshooting, and maintenance. For organisations without Linux expertise, the staff training and support costs may exceed the licence savings. For organisations with Linux-competent teams, Ubuntu is effectively zero-cost infrastructure.

EU Compliance & Privacy

Canonical Ltd. is headquartered in London, United Kingdom. Post-Brexit, the UK has an EU adequacy decision for data protection, meaning data transfers between the EU and UK remain lawful. Canonical's distributed workforce and global infrastructure mean that some services (such as the Snap Store and Ubuntu Pro authentication) may involve non-EU processing, though the operating system itself runs locally with no mandatory data transmission.

Ubuntu's open-source nature provides transparency that proprietary operating systems cannot match. Any data collection behaviour can be audited by examining the source code. Ubuntu Desktop does include optional telemetry collection during installation (system hardware information for compatibility planning), which can be disabled.

For organisations with strict data sovereignty requirements, Ubuntu's local installation model — where the OS runs entirely on local hardware with no cloud dependencies — provides inherent compliance. Unlike Windows (which transmits telemetry to Microsoft) or macOS (which integrates deeply with iCloud), Ubuntu can operate fully air-gapped.

FIPS 140-2 certified modules are available through Ubuntu Pro for organisations that require certified cryptographic implementations.

Who It's Best For

Cloud and DevOps teams deploying workloads on AWS, Azure, or Google Cloud, where Ubuntu's dominance provides ecosystem compatibility and community support.

Developers who need a full-featured Linux development environment with access to every major programming language and tool.

Organisations seeking to reduce software licensing costs by replacing Windows Server or desktop licences with a free, enterprise-supported alternative.

European organisations that want an open-source operating system from a European company, with the transparency and auditability that open source provides.

The Verdict

Ubuntu's greatest achievement is not technical — it is cultural. It made Linux approachable, then it made Linux dominant in the cloud, then it made Linux the default development environment even for Windows users (via WSL). The desktop experience still requires more patience than Windows or macOS for non-technical users, and the Snap ecosystem remains divisive. But as infrastructure — as the operating system that runs the internet's backend, trains AI models, and powers containers from edge to cloud — Ubuntu has no peer at its price point. It is free, it is European, it is open source, and it works.

Frequently Asked Questions

Is Ubuntu really free for business use?

Yes. Ubuntu Desktop and Server are free for any use, including commercial. Ubuntu Pro, which adds extended security maintenance and compliance tools, is free for up to 5 machines for personal use. Commercial Ubuntu Pro starts at USD 25 per desktop per year. There are no licence fees for the core operating system regardless of scale.

Can Ubuntu replace Windows on a company's desktops?

For roles that primarily use web applications, email, and office productivity, Ubuntu with LibreOffice can replace Windows. However, Windows-only enterprise software (certain ERP systems, specialised industry tools, Adobe Creative Suite) does not run natively on Ubuntu. Each organisation must audit its software requirements before committing to a migration.

What is the difference between Ubuntu and Ubuntu Pro?

Ubuntu is the free operating system with 5 years of security updates on LTS releases. Ubuntu Pro adds 10-year security maintenance, kernel livepatching (patching without reboots), FIPS 140-2 certified modules, CIS hardening tools, and expanded security coverage for over 30,000 additional packages. Pro is free for personal use on up to 5 machines.

Is Canonical profitable?

Canonical reached profitability in 2023 and has maintained it since. The company generates revenue from Ubuntu Pro subscriptions, managed services, consulting, and enterprise support. Canonical has been preparing for a potential IPO, though no date has been publicly confirmed.

Why is the Snap package system controversial?

Snap packages launch slower than native .deb packages, use more disk space, and the Snap Store backend is proprietary (not open source). Some Linux users view this as contrary to open-source principles. Others value Snap's security sandboxing, automatic updates, and cross-distribution compatibility. Ubuntu has increasingly defaulted to Snap versions of key applications (including Firefox), which has intensified the debate.
