Ubuntu Core: Minimal Linux OS for Security & App Stores

Discover Ubuntu Core, a lightweight Linux operating system designed for IoT and embedded devices, offering secure transactional updates and app stores.

What is Ubuntu Core?

Ubuntu Core is a stripped-down, minimal version of the Ubuntu Linux operating system that is optimized for security and apps on embedded and Internet of Things (IoT) devices. It provides the same Ubuntu foundations but without the desktop environment and associated components.

Some key features of Ubuntu Core include:

  • Small footprint that can run on devices with as little as 128MB of RAM
  • Read-only filesystem that helps prevent system corruption and malware
  • Strict confinement of apps through application snaps to improve security
  • Transactional updates using image-based deltas to ensure integrity and reliability of updates
  • Support for leading CPU architectures like ARM and x86
  • An app store for easy installation of apps and services
  • Automatic updates of both the OS packages and applications

Ubuntu Core targets devices like home gateways, routers, switches, industrial IoT equipment, robotics, self-driving vehicles, and more. Its immutable infrastructure, strict confinement, and transactional updates are optimized for long-term field deployment with high security and resilience.
