Arch Linux
Arch Linux
Arch Linux is an independently developed, x86-64 general-purpose GNU/Linux distribution that strives to provide the latest stable versions of most software by following a rolling-release model. The default installation is a minimal base system, configured by the user to only add what is purposely required. Arch Linux defines simplicity as without unnecessary additions or modifications. It ships software as released by the original developers (upstream) with minimal distribution-specific (downstream) changes, patches not accepted by upstream are avoided, and Arch's downstream patches consist almost entirely of backported bug fixes that are obsoleted by the project's next release. Arch ships the configuration files provided by upstream with changes limited to distribution-specific issues like adjusting the system file paths. It does not add automation features such as enabling a service simply because the package was installed. -

Whether it’s an IoT sensor monitoring industrial devices or an edge system that must act instantly on external inputs, SUSE Linux Enterprise Real Time is a real time operating system designed to reduce latency and increase the predictability and reliability of time-sensitive, business-critical applications. Banks, manufacturers, government agencies and others rely on time-dependent applications which must execute accurately and predictably all the time, every time. To act as a single unit, distributed systems need time accuracy not only within a server but across all servers. The Precision Time Protocol (PTP) synchronizes servers via the high-speed network, up to sub-microsecond accuracy. Includes support for device interrupt threads, enabling tuning at the device level, and hardware latency detectors to ensure predictability of application behavior. SUSE Linux Enterprise Real Time gives you the time advantage you need to beat the competition.Starting Price: $2,199 per year
