Chromium OS
Google
Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web. Here you can review the project's design docs, obtain the source code, and contribute. We think of Chromium as a tabbed window manager or shell for the web rather than a browser application. We avoid putting things into our UI in the same way you would hope that Apple and Microsoft would avoid putting things into the standard window frames of applications on their operating systems. The tab is our equivalent of a desktop application's title bar; the frame containing the tabs is a convenient mechanism for managing groups of those applications. In future, there may be other tab types that do not host the normal browser toolbar. -

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. -

Tailed
Tailed
Leading DTC brands trust Tailed to prevent fraudulent returns from being automatically refunded. After securing a fraudulent refund, fraudsters spread the word of your brand’s weakness to invite more exploitation. Once the merchandise is received, the fraudster initiates a return and requests a return label. Fraudsters then alter the return label’s shipment address, redirecting the package to a random address near, but not at, the original destination. An automatic refund is then triggered during the “in-transit” or “delivered” tracking event, based on how your brand processes refunds. Retailers using Tailed have seen significant reductions in FTID fraud. One apparel brand, for example, reduced its FTID fraud rate from 14.3% of all returns to 0% after integrating Tailed. Their Fraud Analyst confirmed that manually checking every return was not feasible, and Tailed’s automation has made this process more efficient, saving both time and resources. -

Scientific Linux
Scientific Linux
Scientific Linux is a Fermilab sponsored project. Our primary user base is within the High Energy and High Intensity Physics community. However, our users come from a wide variety of industries with various use cases all over the globe, and sometimes off of it! Scientific Linux is a rebuild of Red Hat Enterprise Linux (property of Red Hat Inc NYSE:RHT). We informally call them “The Upstream Vendor” or “TUV”. Our references to TUV are intended to make it clear that Scientific Linux is in no way affiliated, supported, or sanctioned by upstream. By not using their name we hope to make this distinction as clear as possible. Provides a stable, scalable, and extensible operating system for scientific computing. Supports scientific research by providing methods and procedures for enabling the integration of scientific applications with the operating environment. Use the free exchange of ideas, designs, and implementations to prepare a computing platform for the next generation of computing. -

openSUSE Leap
openSUSE
A brand new way of building openSUSE and a new type of a hybrid Linux distribution. Leap uses source from SUSE Linux Enterprise (SLE), which gives Leap a level of stability unmatched by other Linux distributions, and combines that with community developments to give users, developers and sysadmins the best stable Linux experience available. If you’re already running openSUSE you can upgrade by booting from the DVD/USB and choosing upgrade, or carry out an ‘Online Upgrade’ in a few commands. Leap is a classic stable distribution approach, one release each year and in between security and bugfixes. This makes Leap very attractive as server operating system, but as well for Desktops since it requires little maintenance effort. openSUSE Leap is compatible with SUSE Linux Enterprise; this gives Leap a level of stability unmatched by other Linux distributions and provides users the ability to migrate to an enterprise offering. -

CentOS
CentOS
CentOS Linux is a community-supported distribution derived from sources freely provided to the public on Red Hat or CentOS git for Red Hat Enterprise Linux (RHEL). As such, CentOS Linux aims to be functionally compatible with RHEL. The CentOS Project mainly changes packages to remove upstream vendor branding and artwork. CentOS Linux is no-cost and free to redistribute. Each CentOS version is maintained until the equivalent RHEL version goes out of general support. A new CentOS version is made available once a new RHEL version is rebuilt - approximately every 6-12 months for minor point releases and several years for major version bumps. The length of time the rebuild takes varies from weeks for point releases to months for major version bumps. This results in a secure, low-maintenance, reliable, predictable and reproducible Linux environment. -

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

Flatcar Container Linux
Kinvolk
The introduction of container-based infrastructure was a paradigm shift. A Container-optimized Linux distribution is the best foundation for cloud native infrastructure. A minimal OS image only includes the tools needed to run containers. No package manager, no configuration drift. Delivering the OS on an immutable filesystem eliminates a whole category of security vulnerabilities. Automated atomic updates mean you get the latest security updates and open source technologies. Flatcar Container Linux is designed from the ground up for running container workloads. It fully embraces the container paradigm, including only what is required to run containers. Your immutable infrastructure deserves an immutable Linux OS. With Flatcar Container Linux, you manage your infrastructure, not your configuration.
