Better security. More packages. Newer tools. All your open source, from cloud to edge. Secure your open source apps. Patch the full stack, from kernel to library and applications, for CVE compliance. Governments and auditors certify Ubuntu for FedRAMP, FISMA and HITECH. Rethink what’s possible with Linux and open source. Companies engage Canonical to drive down open source operating costs. Automate everything: multi-cloud operations, bare metal provisioning, edge clusters and IoT. Whether you’re a mobile app developer, an engineering manager, a music or video editor or a financial analyst with large-scale models to run — in fact, anyone in need of a powerful machine for your work — Ubuntu is the ideal platform. Ubuntu is used by thousands of development teams around the world because of its versatility, reliability, constantly updated features, and extensive developer libraries.

Debian is distributed freely over Internet. This page has options for installing Debian Stable. If you are interested in Testing or Unstable, visit our releases page. Many of the vendors sell the distribution for less than US$5 plus shipping (check their web page to see if they ship internationally). You can try Debian by booting a live system from a CD, DVD or USB key without installing any files to the computer. When you are ready, you can run the included installer (starting from Debian 10 Buster, this is the end-user-friendly Calamares Installer). Provided the images meet your size, language, and package selection requirements, this method may be suitable for you. Read more information about this method to help you decide.

Fedora Workstation is a reliable, powerful, and easy-to-use operating system for desktop and laptop computers. It is functional for a wide range of developers, from hobbyists and students to professionals in business environments. Focus on your code with the GNOME 3 desktop environment. GNOME is developed with the needs of developers in mind and is free from unnecessary distractions, so you can focus on what really matters. Avoid the hassle of trying to find or compile the tools you need. With Fedora's comprehensive collection of open source languages, tools, and utilities, it's just a click or command away. There are even hosting projects and repositories like COPR to share your code and make builds available to the entire community.

You install it once and enjoy it forever. No longer do you have to worry every six months about massive system upgrades that risk bricking your system. You get frequent updates that not only address vulnerabilities or squash bugs, but reflect latest features and developments, such as fresh kernels, fresh drivers and recent desktop environment versions. Updates are thoroughly tested against industry-grade quality standards, taking advantage of a build service other Linux distributions envy us. Not only is each new version of a package individually tested, but different clusters of versions are are tested against each other, making sure your system is internally consistent. With a single command you can update thousands of packages, rollback to last week’s snapshot, fast-forward again, and even preview upcoming releases.

Microservice OS providing transactional (Atomic) updates upon a read-only btrfs root filesystem. Designed to host container workloads with automated administration & patching. Installing openSUSE MicroOS you get a quick, small environment for deploying containers, or any other workload that benefits from transactional updates. As rolling release distribution, the software is always up-to-date. MicroOS offers an offline image. The main difference between the offline and self-install/raw images is that the offline image has an installer. Raw and self-install allows for customization via combustion or manually in the image after it is written to the disk. There is an option for a real-time kernel. Try MicroOS in VMs running on either Xen or KVM. Using a Raspberry Pi or other system-on-chip hardware may use the preconfigured image together with the combustion functionality for the boot process.

Red Hat Enterprise Linux is an enterprise Linux operating system, certified on hundreds of clouds and with thousands of vendors. Red Hat Enterprise Linux provides a consistent foundation across environments and the tools needed to deliver services and workloads faster for any application. Red Hat Enterprise Linux reduces deployment friction and costs while speeding time to value for critical workloads, enabling development and operations teams to innovate together in any environment. Red Hat Enterprise Linux extends your hybrid cloud infrastructure to the edge—across hundreds of thousands of nodes all over the world. Create edge-optimized OS images, minimize workload interruptions caused by OS updates, transfer system updates more efficiently, and have confidence in automatic health checks and rollbacks. Run purpose-built command line utilities to automate many inventory and remediation steps associated with upgrading your subscription or migrating from another Linux distro.

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 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.
