Red Hat Fedora Linux 21 has been released in three avatars in its beta version.
Known as Server, Cloud, and Workstation, Fedora 21 offers the public an indication of Project Atomic, which is a Red Hat’s project to create a Linux distribution elevated as a Docker container host.
Past users of Fedora, who had it deployed in a workstation backdrop, can transition to the new Fedora 21 Workstation. Apart from featuring all updates of the earlier version, Fedora 21 also provides Wayland display server’s technology trailer, considered an enhancement on the display server of X.org that is reportedly being used by Linux versions. Included in the workstation is the Dev Assistant tool, which offers developers a quicker way to represent project atmospheres.
Fedora 21 Cloud is said to facilitate one of the better concepts of the ‘atomic’. It comes in two types of images. One can be deployed in traditional cloud milieus, such as AWS, and a slender variant improved as a Docker host.
The other atomic variant has minimum moving parts and keeps the system updated using Red Hat project rpm-ostree minus the restrictions of Fedora's package manager.
The Cloud kernel is also available in two variants, which is governed by its use case.
In the case of cloud implementations, a slimmer kernel features very few components. To implement onto bare metal, another kernel is offered by Fedora with the complete accompaniment of add-ons.
Fedora has been a pioneer in providing new features across all Linux surfaces, therefore, in Fedora 21 Server too, it features a new functionality targeted at consumers who use application-stack servers. A major feature of this Server is a Rolekit toolkit, which is still in its nascent stages. When ready, it promises users to implement a definite type of server functionality with just one click. All this with the settings for the aspect available through an API, and which has not just come out of a scripted process. It, however, comes with the Cloud.
People developing Fedora believe that it would be chosen on a server in place of Red Hat Enterprise Linux because it would feature all the latest versions’ tools and maintenance for the latest hardware
In short, the latest features in Fedora 21 are Gnome 3.14, the latest desktop of Gnome; the Wayland Technology Preview, which is cutting-edge display server placed as a potential replacement for X.org in the future; and DevAssistant, which is a tool that lets developers arrange project environments where they can afford to concentrate on code only.
