Fedora 26 Powers Up Cloud, Server, Workstation Systems
============================================================
[**What Every CSO Must Know About Open Source | Download the White Paper**][9]
[][10]Flexera Software shares application security strategies for security and engineering teams to manage open source.
**[Download Now!][3]**
The [Fedora Project][4] this week announced the general availability of Fedora 26, the latest version of the fully open source Fedora operating system.
![Fedora 26 Powers Up Cloud, Server, Workstation Systems](http://www.linuxinsider.com/ai/631127/fedora.jpg)
Fedora Linux is the community version of Red Hat Enterprise Linux, or RHEL. Fedora 26 comprises a set of base packages that form the foundation of three distinct editions targeting different users.
Fedora Atomic Host edition is an operating system for running container-based workloads. Fedora Server edition installs the Fedora Server OS on a hard drive. Fedora Workstation edition is a user-friendly operating system for laptops and desktop computers, suitable for a broad range of users -- from hobbyists and students to professionals in corporate environments.
All three editions share a common base and some common strengths. All of the Fedora editions are released twice a year.
The Fedora Project is a testing ground for innovations and new features. Some will be implemented in upcoming releases of RHEL, said Matthew Miller, Fedora Project Leader.
"Fedora is not directly involved in those productization decisions," he told LinuxInsider. "Fedora provides a look at many ideas and technologies, and it is a great place for Red Hat Enterprise Linux customers to get involved and provide feedback."
### Package Power
The Fedora developers updated and improved the packages powering all three editions. They made numerous bug fixes and performance tweaks in Fedora 26 to provide an enhanced user experience across Fedora's use cases.
These packages include the following improvements:
* Updated compilers and languages, including GNU Compiler Collection 7, Go 1.8, Python 3.6 and Ruby 2.4;
* DNF 2.0, the latest version of Fedora's next-generation package management system with improved backward compatibility with Yum;
* A new storage configuration screen for the Anaconda installation program, which enables bottom-up configuration from devices and partitions; and
* Fedora Media Writer updates that enable users to create bootable SD cards for ARM-based devices, like Raspberry Pi.
The cloud tools are essential to users with a cloud presence, especially programmers, noted Roger L. Kay, president of [Endpoint Technologies Associates][5].
"Kubernetes is essential for programmers interested in writing from the hybrid cloud, which is arguably one of the more important developments in the industry at the moment," he told LinuxInsider. "Cloud -- public, private and hybrid -- is key to the future of enterprise computing."
### Fedora 26 Atomic Host Makeover
Linux containers and container orchestration engines have been expanding in popularity. Fedora 26 Atomic Host offers a minimal-footprint operating system tailored for running container-based workloads across environments, from bare metal to the cloud.
Fedora 26 Atomic Host updates are delivered roughly every two weeks, a schedule that lets users keep pace with upstream innovation.
Fedora 26 Atomic Host is available for Amazon EC2\. Images for OpenStack, Vagrant, and standard installer ISO images are available on the [Fedora Project][6]website.
A minimal Fedora Atomic container image also made its debut with Fedora 26.
### Cloud Hosting
The latest release brings new capabilities and features to Fedora 26 Atomic Host:
* Containerized Kubernetes as an alternative to built-in Kubernetes binaries, enabling users to run different versions of the container orchestration engine more easily;
* The latest version of rpm-ostree, which includes support for direct RPM install, a reload command, and a clean-up command;
* System Containers, which provide a way of installing system infrastructure software, like networking or Kubernetes, on Fedora Atomic Host in a container; and
* Updated versions of Docker, Atomic and Cockpit for enhanced container building, system support and workload monitoring.
Containerizing Kubernetes is important for Fedora Atomic Host for two big reasons, according to the Fedora Project's Miller.
"First, it lets us remove it from the base image, reducing the size and complexity there," he explained. "Second, providing it in a container makes it easy to swap in different versions without disrupting the base or causing trouble for people who are not ready for a change quite yet."
### Server-Side Services
Fedora 26 Server provides a flexible, multi-role platform for data center operations. It also allows users to customize this edition of the Fedora operating system to fit their unique needs.
New features for Fedora 26 Server include FreeIPA 4.5, which improves running the security information management solution in containers, and SSSD file caching to speed up the resolution of user and group queries.
Fedora 26 Server edition later this month will add a preview of Fedora's modularity technology delivered as "Boltron." As a modular operating system, Boltron enables different versions of different applications to run on the same system, essentially allowing for leading-edge runtimes to be paired with stable databases.
### Workstation Workout
Among the new tools and features for general users is updated GNOME desktop functionality. Devs will get enhanced productivity tools.
Fedora 26 Workstation comes with GNOME 3.24 and numerous updated functionality tweaks. Night Light subtly changes screen color based on time of day to reduce effect on sleep patterns. [LibreOffice][7] 5.3 is the latest update to the open source office productivity suite.
GNOME 3.24 provides mature versions of Builder and Flatpak to give devs better application development tools for easier access across the board to a variety of systems, including Rust and Meson.
### Not Just for Devs
The inclusion of updated cloud tools in a Linux distro targeting enterprise users is significant, according to Scott Sellers, CEO of [Azul Systems][8].
"The cloud is a primary development and production platform for emerging companies, as well as some of the largest enterprises on the planet," he told LinuxInsider.
"Given the cutting-edge nature of the Fedora community, we would expect a strong cloud focus in any Fedora release, and Fedora 26 does not disappoint," Sellers said.
The other feature set of immediate interest to the Fedora developer and user community is the work the Fedora team did in terms of modularity, he noted.
"We will be looking at these experimental features closely," Sellers said.
### Supportive Upgrade Path
Users of Fedora, more than users of other Linux distros, have a vested interest in upgrading to Fedora 26, even if they are not heavy cloud users, according to Sellers.
"One of the primary advantages of this distro is to get an early look at production-grade advanced technologies that [eventually] will be integrated into RHEL," he said. "Early reviews of Fedora 26 suggest that it is very stable, with lots of bug fixes as well as performance enhancements."
Users interested in upgrading from earlier Fedora editions may find an easier approach than wiping existing systems to install Fedora 26, noted Fedora's Miller. Fedora maintains two releases at a time, plus a month of overlap.
"So, if you are on Fedora 24, you should upgrade in the next month," he said. "Happy Fedora 25 users can take their time. This is one of the advantages of Fedora over fast-moving rolling releases."
### Faster Delivery
Users can schedule their own upgrades rather than having to take them when the distro makes them.
That said, users of Fedora 23 or earlier should upgrade soon. The community no longer produces security updates for those releases.

Fedora 26 助力云、服务器、工作站系统
============================================================
[Fedora 项目][4]本周宣布推出 Fedora 26, 它是全面开放源代码的 Fedora 操作系统的最新版本。
![Fedora 26 Powers Up Cloud, Server, Workstation Systems](http://www.linuxinsider.com/ai/631127/fedora.jpg)
Fedora Linux 是 Red Hat Enterprise Linux 或 RHEL 的社区版本。Fedora 26 包含一组基础包，形成针对不同用户的三个不同版本的基础。
Fedora Atomic Host Edition 是用于运行基于容器工作的操作系统。Fedora Server 版将 Fedora Server OS 安装在硬盘驱动器上。Fedora Workstation 版本是一款用于笔记本电脑和台式机的用户友好操作系统，它适用于广泛的用户 - 从业余爱好者和学生到企业环境中的专业人士。
所有这三个版本都有共同的基础和一些共同的优点。所有 Fedora 版本每年发行两次。
Fedora 项目是创新和新功能的测试基地。Fedora 项目负责人 Matthew Miller 说，有些将在即将发布的 RHEL 版本中实现。
他告诉 LinuxInsider：“Fedora 并没有直接参与这些产品化决策。Fedora提供了许多想法和技术，它是 Red Hat Enterprise Linux 客户参与并提供反馈的好地方。”
### 安装包能力
Fedora 开发人员更新和改进了所有三个版本的软件包。他们在 Fedora 26 中进行了许多错误修复和性能调整，以便在 Fedora 的用例中提供更好的用户体验。
这些安装包包括以下改进：
* 更新的编译器和语言，包括 GNU 编译器集合 7、Go 1.8、Python 3.6 和 Ruby 2.4;
* DNF 2.0 是 Fedora 下一代包管理系统的最新版本，它与 Yum 的向后兼容性得到改善;
* Anaconda 安装程序的新存储配置界面，可从设备和分区进行自下而上的配置;
* Fedora Media Writer 更新，使用户可以为基于 ARM 的设备（如 Raspberry Pi）创建可启动的 SD 卡。
[Endpoint Technologies Associates][5] 的总裁 Roger L. Kay 指出，云工具对于使用云的用户必不可少，尤其是程序员。
他对 LinuxInsider 表示：“Kubernetes 对于在混合云中编程感兴趣的程序员来说是至关重要的，这可能是目前业界更重要的发展之一。云 -- 公共，私有和混合 - 是企业计算未来的关键。”
### Fedora 26 Atomic Host 亮相
Linux 容器和容器编排引擎一直在普及。Fedora 26 Atomic Host 提供了一个最小占用的操作系统，专门用于在裸机到云端的环境中运行基于容器的负载。
Fedora 26 Atomic Host 更新大概每两周发布一次，这个时间表让用户跟上游创新。
Fedora 26 Atomic Host 可用于 Amazon EC2 。OpenStack、Vagrant 镜像和标准安装程序 ISO 镜像可在[ Fedora 项目][6]网站上找到。
最小化的 Fedora Atomic 容器镜像也在 Fedora 26 上首次亮相。
### 云托管
最新版本为 Fedora 26 Atomic Host 提供了新功能和特性：
* 容器化的 Kubernetes 作为替代内置的 Kubernetes 二进制文件，使用户更容易地运行不同版本的容器编排引擎;
* 最新版本的 rpm-ostree，其中包括支持直接 RPM 安装，重新加载命令和清理命令;
* 系统容器，它提供了一种在容器中的 Fedora Atomic Host 上安装系统基础设施软件（如网络或 Kubernetes）的方法;
* 更新版本的 Docker、Atomic和 Cockpit，用于增强容器构建，系统支持和负载监控。
根据 Fedora 项目的 Miller 所言，容器化的 Kubernetes 对于 Fedora Atomic Host 来说是重要的，有两个重要原因。
他解释说：“首先，它可以让我们从基础镜像中删除它，减小大小和复杂度。第二，在容器中提供它可以轻松地在不同版本中切换，而不会破环基础，或者为尚未准备好进行改变的人造成麻烦。”
### 服务器端服务
Fedora 26 Server 为数据中心操作提供了一个灵活的多角色平台。它还允许用户自定义此版本的 Fedora 操作系统以满足其独特需求。
Fedora 26 Server 的新功能包括 FreeIPA 4.5，它可以改进容器中运行的安全信息管理解决方案，以及 SSSD 文件缓存，以加快用户和组查询的速度。
Fedora 26 服务器版月底将增加称为 “Boltron” 的 Fedora 模块化技术预览。作为模块化操作系统，Boltron 使不同版本的不同应用程序能够在同一个系统上运行，这实质上允许将前沿运行时与稳定的数据库配合使用。
### Workstation 打磨
对于一般用户的新工具和功能之一是更新的 GNOME 桌面功能。开发将获得增强生产率工具。
Fedora 26 Workstation 附带 GNOME 3.24 和众多更新的功能调整。夜光根据时间细微地改变屏幕颜色，以减少对睡眠模式的影响。[LibreOffice][7] 5.3 是开源办公生产力套件的最新更新。
GNOME 3.24 提供了 Builder 和 Flatpak 的成熟版本，它为开发人员提供了更好的应用程序开发工具，它可以方便地访问各种系统，包括 Rust 和 Meson。
### 不只是为开发
根据[Azul Systems][8] 的首席执行官 Scott Sellers 的说法，更新的云工具将纳入针对企业用户的 Linux 发行版中。
他告诉 LinuxInsider：“云是新兴公司以及地球上一些最大的企业的主要开发和生产平台。”
Sellers说：“鉴于 Fedora 社区的前沿性质，我们预计在任何 Fedora 版本中都会有强大的云，Fedora 26 不会不令人失望。”
他指出，Fedora 开发人员和用户社区的另一个特点就是 Fedora 团队在模块化方面所做的工作。
Sellers 说：“我们将密切关注这些实验功能。”
### 支持的升级方式
Sellers 说 Fedora 的用户超过其他 Linux 发行版的用户，很多都有兴趣升级到 Fedora 26，即使他们不是重度云端用户。
他说：“这个发行版的主要优点之一就是能提前看到先进的生产级别技术，这些最终将被整合到 RHEL 中。Fedora 26 的早期评论表明它非常稳定，修复了许多错误以及性能提升。”
Fedora 的 Miller 指出，有兴趣从早期 Fedora 版本升级的用户可能比擦除现有系统安装 Fedora 26 更容易。Fedora 一次维护两个版本，再加上一个月的重叠。
他说：“所以，如果你在用 Fedora 24，你应该在下个月升级。幸运的 Fedora 25 用户可以随时升级，这是 Fedora 快速滚动版本的优势之一。”
### 更快的发布
用户可以安排自己升级，而不是在发行版制作出来时进行升级。
也就是说，Fedora 23 或更早版本的用户应该尽快升级。社区不再为这些版本发布安全更新
