![]() Ubuntu Core currently supports container runtimes and orchestrators such as snapd, Docker, LXD, AWS Greengrass, Azure IoT Edge, and Kubernetes. ![]() Updates to connected devices occur several times a day automatically and atomically using deltas that can be instantly rolled back if a buggy update is installed or if the update process is interrupted. Ubuntu Core offers a secure, modular, immutable container-based OS built on snaps. Ubuntu Core is based on Debian and is essentially an IoT-optimized version of Ubuntu that you can customize to include only the packages and binaries required to power your single-purpose, single-function IoT devices. Ubuntu Core is the most popular embedded Linux distro, likely because most manufacturers and developers are already familiar with Ubuntu. Some of the most popular IoT Linux distros have been described here for you. ![]() This makes them suitable even for low-spec single-purpose, single-function IoT devices that often only have 64MB of RAM and 32MB of storage space. The key difference between traditional Linux distros for desktops and embedded Linux distros is that the latter only includes drivers and libraries required to run on the target processor, requiring as little as 100KB of space. Fortunately, since the Linux kernel is open source, its source code can be modified and repurposed for redistribution, which has led to the emergence of several standard Linux distros for IoT devices in the market. However, developers may find it time-consuming and tedious to integrate these diverse tools and packages into a comprehensive OS that can support a wide array of functionalities. ![]() What are IoT Linux distros?Ī typical Linux OS integrates tools and packages from numerous developers and organizations (for example, GNU tools and libraries) to create a functional OS for a device, commonly known as a Linux distribution or Linux distro. As an open-source project, Linux offers a stable, low-cost, secure, and up-to-date platform that can be run on a variety of microprocessor architectures, powering a range of devices from IoT sensors at the low end to powerful supercomputers. Linux is the operating system of choice for Internet of Things device manufacturers looking to fit their resource-constrained embedded devices with lightweight software systems. ![]()
