If you want to know the future development trend of Enterprise Edition Linux, you should look at the Red Hat community Linux release, Fedora. After several delays, in February 21 of this month, Fedora officially released its latest version of Fedora 21, which brought many new features and new ideas.

For a long time, RedHat has always been the latest development achievements of Linux and open-source software on the Fedora release. At the same time, not everyone likes the ora option, for example, the init ora init system systemd is still under criticism and controversy. Despite this, Fedora is still the leader in the Linxu camp, which means the future development direction of the Linux release. If a software is not included in Fedora, it will not appear in other mainstream Linux distributions in a sense.

The latest version of Fedora, that is, Fedora 21, has been postponed several times, but it is a little too late. However, it runs very well.

Unlike the previous desktop version, Fedora is now released in three different sub-versions: Fedora 21 Cloud, Fedora 21 Server, and Fedora 21 Workstation.

Each sub-version is provided to a dedicated user, but all sub-versions share the same software repository, the new Linux 3.18 kernel, RPM, yum, systemd, and Anaconda installers are available. According to the Red Hat description, "this small and stable component set creates a very stable basic operating platform based on Fedora.

New features of the latest Fedora version include:

Fedora 21 Cloud (Cloud scenario Edition)

Fedora 21 Cloud provides use cases in private Cloud environments, such as Amazon Machine Images used by OpenStack, Amazon Web Services, and a basic image to activate the creation of the Fedora container. Important features of Fedora 21 Cloud include:

  • Modular kernel packaging for cloud computing-To save space and avoid scaling during Cloud deployment, the Fedora 21 Cloud kernel only contains the minimum number of modules that need to be run in a virtual environment. The entire Fedora 21 Cloud image is about 25% less than the size of the previous version of Fedora, and enables fast deployment for key applications and requires elastic space allocation.
  • Fedora atomic host-This is the first "Atomic" host brought by Fedora, including the smallest package set, this image only contains the most basic runtime required by optimized Linux containers. The ora atomic host allows "Atomic" Update as an independent unit to simplify update management. If necessary, it can also provide rolling update capabilities, it also includes Google's container cluster management system Kubernetes for configuration and Cockpit for general container management.
Fedora 21 Server (Server Version)

The sub-version of Fedora 21 Server provides a general basic Platform to run the index Application Stack, such as network servers, file servers, database servers, and even PaaS (Platform-as-a-Service) provides a sound and flexible operation foundation. Fedora 21 Server brings these new features:

  • New management functions-Fedora 21 Server introduces three new technologies (as follows) to handle discrete infrastructure installation services and management.
  • Rolekit provides an unfamiliar User Role and management tool to help administrators install and configure dedicated server roles.
  • Cockpit is a web-based user interface that can be used to configure, manage, and monitor servers. It can be used in any remote web browser.
  • Openlms is a remote Management system that provides a remote Management system built on a DMTF-CIM (Distributed Management Taskforce-Common Information Model) and provides script Management for machines, compatibility query and system event monitoring.
  • Domain Controller-this is also one of Rolekit's features. The ora 21 Server Pack freeIPA to provide integrated identity and authentication solutions for Linux/UNIX network environments. Machines running the ora 21 Server Edition can provide centralized, unified identity authentication, authorization, and account information without worry, and manage network security by storing users, groups, hosts, and other necessary object data.
Fedora 21 Workstation (Workstation Edition)

The purpose of the ora Workstation Edition is to provide a smooth experience for ordinary desktop users and software program developers, develop and entertain, and meet all common basic needs. New Features of workora 21 Workstation include:

  • Simplified Software Installation-The software installer is a basic component of workora 21 Workstation. The new software installer helps users quickly and easily select the applications they need, it provides an elastic and Fast User Experience, and allows you to install a large number of Fedora applications that greatly increase the quantity and quality in Fedora 21 Workstation.
  • Support Wayland Technology-Wayland is a very powerful next-generation Display Server technology. It already has an experimental compilation version included in Fedora 21, this allows developers to test and integrate their application's compatibility with Wayland.
  • DevAssistant)-A developer's help center can automate the installation process for a large number of runtime and integrated development environments (IDE). The Development Assistant also integrates the Fedora software set, different versions are provided in multiple languages, so you don't have to worry about system software conflicts.

Fedora has many sub-versions. If you are not familiar with it at the beginning, Fedora 21's default desktop is GNOME 3.14.2, but it also provides other desktops such as KDE, LXDE, and XFCE, many loyal traditional Fedora users also like to use the MATE desktop.

At the same time, I tried to install the ora 21 workstation sub-version on my older IBM ThinkPad notebook, what's hateful is that my common ordinary touchpad cannot be driven, and in the past it was running normally on my computer. (Ps: running well on another Acer TravelMate 8481 notebook)
