Development Editor Akashdeep Kundu Technical Editors Naveenkumar Jain Narsimha Pai www.it-ebooks.info www.it-ebooks.info 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 www.it-ebooks.info 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 Tim Bell Infrastructure Manager, CERN www.it-ebooks.info 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 www.it-ebooks.info Cody Bunch is a principal architect in the Rackspace Private Cloud group based out of San Antonio, Texas Cody has been working with OpenStack since early 2012, coauthored the second edition of this book and also coauthored OpenStack Security Guide Cody has extensive experience with virtualized and cloud environments in various-sized enterprises and hosting environments Cody can be found on Twitter at @cody_bunch I'd like to thank Kevin for coming along on this crazy ride, yet again I would also like to thank Egle, who jumped into the fray and has gone above and beyond to make this book more awesome than the last one This book would not be possible without the wonderful reviewers, as well as the folks at Packt who stepped up their game between editions Next up, and likely much more important, to thank are my kids and loving wife Without their support, well, I'm not entirely sure this edition would have made it out the door Also, on the time, understanding, and support list is my employer, Rackspace I'd like to thank the writers, publisher, reviewers, and employer While this is a small army of folks who help with the writing and publishing of this edition, I think it would be super amiss if I didn't thank the awesome-tastic OpenStack community for whom we wrote this Y'all provide not just the support, technical guidance, and such, but also the "why" behind putting another volume out in the market Thanks! www.it-ebooks.info Egle Sigler is an OpenStack Foundation board member and a principal architect in the Rackspace Private Cloud group based out of San Antonio, Texas Egle holds an M.S degree in computer science She started her career as a software developer and still has a soft spot for all the people who write, test, and deploy code, since she has had the chance to all of those tasks throughout her career Egle dreams about a day when writing, testing, and deploying code will be a seamless and easy process—bug and frustration free for all Egle believes that knowledge should be shared and has tried to this by writing this book, giving talks and workshops at conferences, and blogging Egle can be found on Twitter at @eglute She has coauthored DevOps for VMware Administrators (VMware Press Technology) I would like to thank my husband, my love, and my technical advisor for his constant and unwavering support while writing, traveling, installing, and troubleshooting For some reason, it is always the networking that needs troubleshooting I ask for forgiveness from my friends and family, who didn't get to talk to me very much while I was working on this book OpenStack developers, quality engineers, operators, users, and documentation writers, thank you for making OpenStack better each day! Kevin and Cody, thank you for bringing me along on this adventure! I cannot believe how much quality work was already put into this book, as well as into the Vagrant environment scripts Technical reviewers, thank you for volunteering hundreds of hours to review everything Reviewers and editors from Packt, thank you for your prompt communication and constant feedback Rackers, thank you for your advice and guidance Lastly, thanks to Rackspace for supporting my writing endeavors www.it-ebooks.info .. .OpenStack Cloud Computing Cookbook Third Edition Over 110 effective recipes to help you build and operate OpenStack cloud computing, storage, networking, and... 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. .. 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
