Ubuntu Core
The embedded Linux OS for devices
Ubuntu Core is a minimal, secure and strictly confined operating system powering devices around the world. Build your Ubuntu Core image today.
An OS with all the infrastructure
Ubuntu Core is more than just your embedded Linux OS, it's your whole deployment infrastructure. Build targeted production-ready images, unlock over-the air (OTA) updates, deploy in air gap environments, manage your fleet of devices, achieve real-time operations, comply with cybersecurity requirements and more.
Ubuntu Core will transform the way you deploy devices with the longest support window in the industry — 12 years.
Continuous security
Imagine a world where every device is trustworthy. We designed every aspect of Ubuntu Core to create the most secure embedded Linux ever, with a 12 year LTS commitment.
Device management
Enjoy reliable, remotely accessible and recoverable devices which are always up-to-date with mission-critical OTA updates. In connected or air-gap environments.
Agile containerisation
Ubuntu Core is immutable and strictly confined. There is a clean separation between the kernel, OS image and applications, each updated independently and protected against corruption.
A strong hardware ecosystem
We enable Ubuntu Core with the best ODMs and silicon vendors in the world. We continuously test it on leading IoT and edge devices and hardware.
From development to deployment
Use the same kernel, the same libraries, and the same system software for a smooth transition from development to production. Once you have created your application in Ubuntu Desktop or Server, build your immutable Ubuntu Core image based on your developed applications and targeted hardware.
Deploying a device?
Ubuntu is your development environment. Ubuntu Core is your deployment OS. Whether you develop your application using C++, Rust, Python, or others – whatever tech stack you use, package and deploy it seamlessly on Ubuntu Core.
For more than 20 years, Ubuntu has provided the best development environment. Every aspect of the development process benefits from Ubuntu’s responsiveness, ease of use, regular software updates and a high degree of security.
