Ubuntu Core documentation¶
Ubuntu Core is an immutable and transaction-based version of Ubuntu that’s engineered for cloud, embedded, and IoT systems.
It provides an image-based deployment infrastructure with automatic updates for sandboxed applications, enabling the creation of production-ready systems with minimal attack surface and automatic rollback capabilities.
Ubuntu Core reduces the time to production by eliminating manual provisioning, ensuring systems remain secure throughout their lifecycle, and enabling rapid updates across fleets of devices at scale.
It is designed for embedded Linux developers, IoT device manufacturers, cloud-based applications, and organizations deploying embedded systems in robotics, automotive, signage, industrial automation, and IoT applications - from single devices to thousands in the field.
