Development Environment
This bit is thankfully quite easy.
git clone https://github.com/openstack-dev/devstack.git
cd devstack && ./stack.sh
Then load up your web browser and head
to the IP address of the machine to see the
Horizion dashboard. From here you can
create VM's and manage your cloud.

So, why should I care about
OpenStack?
4 It's open source. We currently have too
much proprietary code and vendor lock-
in.
4 Lots of great projects to work on,
challenges to solve and people to work
with.

Also...
Knowing both Python
and/or OpenStack are
really hireable skills
right now.
Red Hat are constantly
looking for great people
in many areas.
