Ubuntu Core real-time processing for Linux IoT

Ubuntu has released Core 22, an ultra-secure embedded Linux which introduces support for real-time compute in robotics and industrial applications.
Ubuntu Core 22 is designed to help manufacturers address challenges of rapid, low cost device deployment by providing an ultra-secure, resilient, and low-touch OS, backed by a growing ecosystem of silicon and ODM partners.
“Our goal at Canonical is to provide secure, reliable open source everywhere – from the development environment to the cloud, down to the edge and to devices,” said Mark Shuttleworth, CEO of Canonical. “With this release, and Ubuntu’s real-time kernel, we are ready to expand the benefits of Ubuntu Core across the entire embedded world.”
The new release includes a fully preemptible kernel to ensure time-bound responses. Canonical has partnered with silicon and hardware manufacturers to enable advanced real-time features out of the box on Ubuntu Certified Hardware.
Ubuntu Core is designed to provide a robust, fully containerised Ubuntu, which breaks down the monolithic Ubuntu image into packages known as snaps – including the kernel, OS and applications. Each snap has an isolated sandbox that includes the application’s dependencies, to make it fully portable and reliable. Canonical’s Snapcraft framework enables on-rails snap development for rapid iteration, automated testing and reliable deployment.
Every device running Ubuntu Core has a dedicated IoT App Store, which offers full control over the apps on their device, and can create, publish and distribute software on one platform. The IoT App Store offers enterprises a sophisticated software management solution, enabling a range of new on-premise features.
The system guarantees transactional mission-critical over-the-air (OTA) updates of the kernel, OS and applications – updates will always complete successfully, or roll back automatically to the previous working version, so a device cannot be “bricked ” by an incomplete update. Snaps also provide delta updates to minimise network traffic, and digital signatures to ensure software integrity and provenance.
Ubuntu Core also provides advanced security features out of the box, including secure boot, full disk encryption, secure recovery and strict confinement of the OS and applications.
“KMC Controls’ range of IoT devices are purpose-built for mission-critical industrial environments. Security is paramount for our customers. We chose Ubuntu Core for its built-in advanced security features and robust over-the-air update framework. Ubuntu Core comes with 10 years of security update commitment which allows us to keep devices secure in the field for their long life. With a proven application enablement framework, our development teams can focus on creating applications that solve business problems,” said Brad Kehler, COO at KMC Controls.
“Advantech provides embedded, industrial, IoT and automation solutions. We continue to strengthen our participation in the Ubuntu Certified Hardware Program. Canonical ensures that certified hardware goes through an extensive testing process and provides a stable, secure, and optimised Ubuntu Core to reduce time to market and development costs for our customers.” said Eric Kao, Director of Advantech WISE-Edge+.
