Modular Kernel Packaging for the Cloud – There’s no reason to include drivers for hardware that doesn’t exist in the cloud, so Fedora 21 Cloud Beta has two kernel packages: one that contains the minimum modules for running in a virtual environment and a larger set for a more general installation. As a result, the Fedora 21 Cloud Beta image is 10 percent smaller than that of Fedora 20, allowing faster deployment.
-
Fedora Atomic Host – Emphasizing the tools and patterns delivered by Project Atomic for a streamlined operating system to run Docker containers, Fedora 21 Cloud Beta is the first to offer an “Atomic” Fedora Host, which includes an image composed with rpm-ostree that allows for rollbacks as one unit, making update management much easier and offering a compelling solution for hosting Docker containers. The Fedora Atomic Host carries a minimal set of packages optimized for running containers.
-
New Management Features – Specifically, Fedora 21 Server Beta introduces three new technologies to make it easier to install discrete infrastructure services:
-
Rolekit – A Role-based deployment and management toolkit to implement a specific server role (like a Web or database server).
-
Cockpit – A remote interface for configuring and monitoring servers.
-
OpenLMI – A remote management system built atop DMTF-CIM and used for scripting management functions across machines, querying capabilities and monitoring system events.
-
-
Domain Controller Server Role – One of the roles offered through Fedora Server 21 Beta’s role deployment mechanism (Rolekit), the Domain Controller Server Role packages up the freeIPA integrated Identity and Authentication solution, providing centralized authentication, authorization and account information by storing user, group, host and object data as needed to manage network security.
-
GNOME 3.14 – The latest GNOME desktop, which includes integration of Picasaweb and Digital Living Network Alliance (DLNA) media server support for increased interoperability with other media devices and much, much more.
-
Wayland Technology Preview – A next-generation display server positioned as a possible X.org replacement in the future, Wayland offers a more modern windowing system for Fedora 21 Beta and will likely serve as the default in the next iteration of Fedora Workstation.
-
DevAssistant – A tool to help developers set up project environments so that they can focus on code and code alone.
