Fedora 21

 

 

 

 

While each variant aims to meet specific user demands, all are built from a common base set of packages that includes the same Linux kernel, RPM, yum, systemd, and Anaconda. This small, stable set of components allows for a solid foundation upon which to base the Fedora 21 variants.

cloud

 

 

 

 

Designed to handle the myriad of computing requirements across different cloud deployments, Fedora 21 Cloud provides images for use in private cloud environments, like OpenStack, and Amazon Machine Images (AMIs) for use on Amazon Web Services (AWS), as well as a base image to enable creation of Fedora containers. Key features of Fedora 21 Cloud include:

Modular Kernel Packaging for Cloud Compuing – To save space and reduce “bloat” in cloud computing deployments, the Fedora 21 Cloud kernel contains the minimum modules needed for running in a virtualized environment; coupled with other size reduction work, the Fedora 21 Cloud image is roughly 25 percent smaller than that of previous Fedora releases, enabling faster deployment and increasing available space for critical applications.

Fedora Atomic Host[1] – Using tools and patterns made available through Project Atomic, Fedora 21 offers the first “Atomic” host for Fedora, which includes a minimal package set and an image composed with only the run-times and packages needed to serve as an optimized host for Linux containers. Fedora Atomic Host allows for ”atomic” updates as a single unit, simplifying update management and providing the ability to roll-back updates if necessary. Fedora Atomic Host also includes Kubernetes for container orchestration and Cockpit for container management.

 

 


server

 

 

 

 

The Fedora 21 Server variant offers a common base platform for running featured application stacks (produced, tested, and distributed by the Fedora Server Working Group), providing a flexible foundation for Web servers, file servers, database servers, and even Platform-as-a-Service (PaaS) deployments. Fedora 21 Server delivers:

New Management Features – Fedora 21 Server introduces three new technologies to handle the management and installation of discrete infrastructure services.

 

Rolekit provides a Role deployment and management toolkit that helps administrators to install and configure a specific server role.

A Rolekit graphical interface should be provided with the cockpit project – see below –  in Fedora 22.

Cockpit[2] is a Web-based user interface for configuring, managing, and monitoring servers, accessible remotely via a Web browser.

openlmi

 

 

 

 

 

OpenLMI[3] delivers a remote management system built on top of Distributed Management Taskforce – Common Information Model (DMTF-CIM), offering scripting management functions across machines, capabilities querying and system event monitoring.

 

freeipa

 

 

 

Domain Controller – One of the roles offered through Rolekit, Fedora 21 Server packages freeIPA’s integrated identity and authentication solution for Linux/UNIX networked environments; machines running Fedora 21 Server can now offer centralized authentication, authorization, and account information by storing user, group, host, and other object data necessary to manage network security.

workstation

 

 

 

Fedora 21

 

 

 

 

 

 

 

 

Revitalizing the Linux desktop, Fedora Workstation provides a polished, targeted system designed to offer a smooth experience for general desktop use as well as software development, from independent Web developers to corporate coders. New features in Fedora 21 Workstation include:

Streamlined Software Installation – The Software installer, a cornerstone component to Fedora 21 Workstation, allows users to quickly and easily locate their applications. It provides a responsive and fast user experience, going hand-in-hand with a greatly improved number of featured Fedora applications included with Fedora 21 Workstation.

Wayland Support (Experimental) – Wayland, a powerful next-generation display server technology, is included in Fedora 21 Workstation as an experimental build, allowing developers to test and integrate their applications with Wayland’s new capabilities.

DevAssistant – A developer “helper,” DevAssistant automates the setup process for a large number of language runtimes and integrated development environments (IDEs); DevAssistant also integrates with Fedora Software Collections, offering access to multiple versions of different languages without worrying about system software conflicts.

Fedora 21 redefines the very nature of the Fedora distribution, so users seeking to try all of the new capabilities for themselves or looking for additional information on all of the new features, enhancements and tweaks, please visit https://getfedora.org.

Dear *,

Following requests from the Fedora community, you will find a presentation on Fedora FOSDEM’10 wiki page explaining the requirements , assumptions, constraints and Business case for the Fedora@FOSDEM’10 project.

For the moment, it is still a DRAFT. So if you have comments, feel free to tell me.

Thanks for reading and you help.

Every parents want the best for their children !

So among other, Parents subscribe for an ADSL service to a provider in order to have Internet at home and let their children freely read, write, learn and play with this amazing tool thinking it is a good thing for them.

At first glance, they are right !

Nonetheless and unfortunately Internet does also contain indecent contents, scams and so on…
Obviously YOU as adult already knows that.

But does YOUR CHILDREN know ?

So you have three choices :

1] Surf the internet with your children.
2] Let’s you children access freely to the Internet and do not care about what she/he/they is/are reading/learning/watching/etc…
3] Set Internet web site ACL- Access control List -/Black List

For my part, I will opt the third option.
So If you are like me then Open Source is the answer !

DansGuardian and SquidGuard are respectively content-control software – software designed to control which websites users can access – and Black List oriented software .
In addition, DansGuardian also includes virus filtering and usage monitoring features. Witch could be useful.
For more details, I invite you to go their respective web site – see below for URL –

BTW, these software can also be used in other domains than Children’s Internet Protection. You see what I mean ? e.g. In business compagny, firm. 😉

Rem: Maybe your provider already offer you this service via your ADSL box.

Message for my Fedora packager Friends, it should be nice to have DansGuardian packaged in the Fedora distribution.
Ok, I could do it myself but do not have time currently. 😦
Thanks for your time.

User Mode Linux is another mean to run independent, safe and secure Virtual Linux distributions, versions and processes on your main Linux system.
Unfortunately, often unknown by System Administrators.

Ok, it use paravirtualized technique but if you are using Linux Virtual machines on Linux Physical Machine it is most of the time responding to your basic needs – e.g. web servers, and so on -.

You will be able to use it on Fedora 10 with the following package : uml_utilities.i386 0:20070815-5.fc10
Otherwise you can download it on the UML website

It contains uml_net, uml_mconsole, uml_switch, tunctl, and a number of other useful utilities in order to use the user-mode linux kernel.

You will find a great article at the following URL : http://www.redhat.com/magazine/001nov04/features/usermode/

Obviously, It exists also other techniques, methods in order to run VM – virtual machines – on Linux and VmWare is probably one of the most known.- Marketing have done its job, you see what I mean 😉 –

However, it is not always the right answer to your needs and requirements.
Here is a list of Open source Virtualized project as well as their associated types and licences:

Emulation type :
Bochs – Licence -> LGPL –
QEMU – Licence -> LGPL/GPL –

Paravirtualization type :
UML – Licence -> GPL –

Paravirtualization and Full virtualization type – with v-processors (Intel, Amd) – :
Xen – Licence -> GPL – (own by Citrix now)

Operating system-level virtualization type :
Linux-VServer – Licence -> GPL –
OpenVZ – Licence -> GPL –

Full Virtualization
KVM – Licence -> GPL (supported by Red Hat)
Virtualbox – Licence -> GPL

Proprietary Solution & Full Virtualization :
VmWare – Licence -> Proprietary Solution –

Now, it is up to you to choose the application which best fit your strategy, your requirements, your budgets and your needs.

BTW, Thanks to Eddy to have shown me what I did not see. 😉

Definitely, “crisis effect” or not it is better and better each year !

Now, to those who say : it depends of the “Head count” ! I will respond : “No, it is up to you to take the risk or not !”
Understand who can ( Well, I do not know if this sentence is correct English expression. – In French : “Comprenne qui peut”-)
