Foreword
At CERN, the European Organization for Nuclear Research, physicists and engineers are
probing the fundamental structure of the universe. They use the world's largest and most
complex scientific instruments to study the basic constituents of matter—the fundamental
particles. The particles are made to collide together at close to the speed of light. The
process gives clues to physicists about how the particles interact and provides insights into
the fundamental laws of nature.
The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator.
The LHC consists of a 27-kilometer ring of superconducting magnets with a number of
accelerating structures to boost the energy of the particles along the way. Inside the
accelerator, two high-energy particle beams travel at close to the speed of light, before they
are made to collide. This produces 27 petabytes of data every year, which is recorded and
analyzed by thousands of computers in the CERN data centre.
With an upgrade to the LHC in 2015 to nearly double the collision energy, it was clear that
further computing resources were needed. To provide the additional capacity and be more
responsive to the users, a new approach was needed. In 2012, a small team at CERN started
looking at OpenStack, a piece of open source software, to create computing clouds. It was a
very promising technology with an enthusiastic community but a significant level of complexity.
Along with the code being very new, those were very early days for the documentation and
training. We wanted to educate people rapidly to start the project and so looked for guides
to make the new administrators productive. This was when we encountered the first edition
of the book, OpenStack Cloud Computing Cookbook. It became the standard document for
newcomers in the team to understand the concepts, set up their first clouds, and then start
work on the CERN cloud.
As the cloud evolved and the OpenStack technology matured, we continued to use this guide,
even as the members of the team rotated, building small clouds to try out new concepts and
investigate the flexibility of cloud computing.
Over the years, I have frequently met Kevin, Cody and Egle at the OpenStack summits that
give the community an opportunity to meet and exchange experiences. With OpenStack
evolving so rapidly, it also gives an opportunity to get the latest editions of the cookbook,
which they have continued to keep up to date.
The CERN cloud is now in production across two data centers in Geneva and Budapest, with
over 3,000 servers running tens of thousands of virtual machines. With new staff members
joining frequently, we continue to use the cookbook as a key part of the team's training and
look forward to the updates in the latest edition.

About the Authors
Kevin Jackson is married and has three children. He is an experienced IT professional
working with business and enterprises of all sizes at Rackspace as an OpenStack and private
cloud specialist. Kevin has been working with OpenStack since early 2011 and has extensive
experience of various flavors of Linux, Unix, and hosting environments. Kevin can be found on
Twitter at @itarchitectkev.
Kevin authored the first edition and coauthored the second edition of the OpenStack Cloud
Computing Cookbook, Packt Publishing. Kevin also coauthored OpenStack Foundation's
OpenStack Architecture Design Guide during a 5-day book sprint in California.
I'd like to thank Cody for stepping up to the plate again to go through the
pain and anguish to get another edition of the book out. Also thanks, of
course, go to Egle, whom we somehow commandeered to help get this out
the door bigger and better than before. We have a whole bunch of tech
reviewers from across the globe too who have helped keep us within reach
of our goals, so thanks for keeping it real.
I'd also like to thank my family, although I'm not sure they have realized
I wrote another one. I think I may have just about gotten away with this
one unscathed.
Finally, I'd like to thank Rackspace for giving me the opportunity and support
to pursue such endeavors and the many people I bug now for answers to
stupid questions.
