Książki

The goal of this book is to teach the fundamentals of OpenStack in a small scale so the operator understands the components and then can move on to build bigger, more horizontally scalable infrastructures that will be touched upon in one of the final chapters. Along the way, tips for growth from their first deployment will be explained.
