Ubuntu Core is a version of the Ubuntu operating system designed and engineered for IoT and embedded systems.
Ubuntu Core updates itself and its applications automatically. Snap packages are used exclusively to create a confined and transaction-based system. Security and robustness are its key features, alongside being easy to install, easy to maintain, and easy to upgrade.
Ubuntu Core is ideal for embedded devices because it manages itself. Whether it’s running on an Intel NUC hidden for media streaming, or a Raspberry Pi handling garage door automation, Ubuntu Core remains transparent, trustworthy and autonomous.
From Linux and maker space tinkerers, to the robotics, automotive and signage industries; from a single device, to a deployment of thousands: Ubuntu Core can handle it.
