What is Fedora
● A community● Linux distribution
● What might become Red Hat Enterprise Linux
F19 - Schrödinger's cat
From science experiment to 'making new things'
● Developer's Assistant● 3D modelling and printing● OpenShift Origin● node.js● Ruby 2.0.0● MariaDB

F19 - Schrödinger's cat
... and so many features are related to 'Cloud'
● OpenShift Origin● OpenStack Grizzly● Virt Storage Migration● systemd Lightweight Containers● QXL/Spice KMS Driver● ...
http://fedoraproject.org/wiki/Releases/19/FeatureList
What is this ...
... and why does it all matter to Fedora ?
● OpenShift Origin (PaaS)● OpenStack Grizzly (IaaS)● oVirt (IaaS)
What is this ...
... and why does it all matter to Fedora ?
● SaaS (Software as a Service)● PaaS (Platform as a Service)● IaaS (Infrastructure as a Service)
What is this ...
... and why does it all matter to Fedora ?
● Full virtualization (hardware)● Paravirtualization● OS level virtualization● Containers● Etc.
What is this ...
... and why does it all matter to Fedora ?
● Hypervisor● SElinux● KVM● LXC
What is this Hypervisor
Virtual Machine Monitor
is a piece of computer software, firmware or hardware that creates and runs
virtual machines.
What is this Hypervisor
Virtual Machine Monitor
Hosted (type 2); needs an OS● VirtualBox, VMware Workstation
Native (type 1); bare metal● XenServer, VMware ESX(i)
What is this virtualization
full virtualization
A full machine is virtualized. Unavailable (needed) hardware is emulated. Runs unmodified OS.
para-virtualization
Virtualization method where parts of the OS talks to an API. Runs only modified OS.
What is this KVM
full virtualization
solution for Linux on x86 hardware containing virtualization extensions
What is this KVM
full virtualization
solution for Linux on x86 hardware containing virtualization extensions
But … but... but...
doesn't it also do para-virtualization?
What is this virtualization
Hybrid ?
What is this OpenS[omething]
What is this OpenStack
a cloud computing project
to provide an
Infrastructure-as-a-Service (IaaS).
What is this IaaS
cloud-service model in which
virtual machines
and other resources are offered. A
hypervisor,
such as Xen or KVM, runs the virtual machines as guests.
OpenStack
OpenStack provides … a lot
OpenStack provides ...
How does this work
KVM
uses hardware extensions provided by your CPU.
It can therefore reach
near-native
performance.
What is this ...
... and why does it all matter to Fedora ?
● Hypervisor● SElinux● KVM● LXC
What is this OS virtualization
operating system-level virtualization
What is this OS virtualization
operating system-level virtualization
provides a means to re-use system installed libraries.
What is this LXC
operating system-level virtualization
method for running
multiple isolated
Linux systems (containers) on a single control host.
What is this SELinux
kernel feature that provides the mechanism for supporting
access control
security policies
What is this cgroups
kernel feature to limit, account and isolate
resource usage
(CPU, memory, disk I/O, etc.) of
process groups.
What is this OpenShift
makes it easy for you to build your own
Platform-as-a-Service (PaaS) infrastructure,
allowing you to enable others to easily
develop and deploy software.
What is this PaaS
In this model cloud providers deliver a
computing platform,
typically including● operating system,● programming language execution
environment,● database, ● and web server.
What is this OpenShift
How does this work
Containers
Operating system-level virtualization where the kernel of the operating system is used for multiple isolated user-space instances.
In addition to isolation mechanisms, the kernel can provide resource management features to limit the impact of one container's activities on the other containers.
How does this work
Containers
provide process-isolation
possibility to allocate resources
How does this work
Containers
LXC / SElinux
cgroups
How does this work
Software deployment works by using
git
When code is pushed to the repository,
hooks
will perform actions on the
post-update

So, what does this mean ...
Fedora is a general Linux distribution, but most of it's core technology is either aimed at a general user or running it as server on mind.
So, what does this mean ...
● Red Hat Enterprise Linux● CentOS
So, what does this mean ...
Voices in the community consider a
'Core'
concept; a small core which can serve as a basis for
Desktop or Server...
… or any other purpose where you see fit.
So, what does this mean ...
… or any other purpose where you see fit.
