OpenStack view from the clouds...
● Building blocks for creating public / private clouds
● Massive scale
● Horizontally scalable services
● Illusion of infinite resources
● Rapid provisioning / tear down of resources
● Modular services with well defined APIs

RDO launched here
too (April 2013)

Getting Started the Easy Way - RDO
● Launched yesterday at the OpenStack Summit :)
● Website at openstack.redhat.com
● OpenStack Grizzly Community release, packaged for
Enterprise Linux 6
● Eg: RHEL 6.x, CentOS 6.x, Scientific Linux 6.x, etc.
● Working well with RHEL derivatives is a core feature
● Also available for Fedora 18/19
● The default OpenStack in Fedora 18 repos is the older
Folsom release. Use RDO if you use Fedora and want
the latest OpenStack.

Getting Started the Easy Way – RDO Quickstart
● http://openstack.redhat.com/Quickstart
● Everything setup on one box for easy hands on experience
● Works fine in a VM, as long as nested virt is enabled
● Uses “PackStack” - OpenStack installer for EL6/Fedora
● 3 Step installation
● $ sudo yum install -y
http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-
release-grizzly-1.noarch.rpm
● $ sudo yum install -y openstack-packstack
● $ packstack --allinone

Useful Links / Getting Started
● Main OpenStack website - http://openstack.org
● openstack@lists.launchpad.net
● IRC: #openstack @ freenode.net
RDO - http://openstack.redhat.com
● QuickStart
● RDO Forums
● More in depth docs than just the QuickStart :)
● Links to useful extra pieces
● eg: How-to's for GlusterFS integration plus more
