Preface

OpenStack is a very popular cloud computing platform that has enabled several organizations to
successfully implement their Infrastructure as a Service (IaaS) platforms in the last few years. This
book will guide you through new features of the latest OpenStack releases and how to bring them into
production straight away in an agile way.
It starts by showing you how to expand your current OpenStack setup and approach your next
OpenStack Data Center generation deployment. You will discover how to extend your storage and
network capacity, and also take advantage of containerization technology, such as Docker and
Kubernetes in OpenStack. In addition, it is an opportunity to explore the power of big data as a
service implemented in OpenStack by integrating the Sahara project. This book will teach you how to
build Hadoop clusters and launch jobs in a very simple way. Then, it will dedicate time to automating
and deploying applications on top of OpenStack. You will discover how to create and publish your
own application in simple steps using the novel application catalog service in OpenStack code named
Murano. The final part of the book will shed the light on the identity service and will go through a
consolidated authentication setup using Keystone. The book will be enclosed by leveraging the right
tool to conduct and extend benchmarking performances tests against an operating OpenStack
environment using the Rally platform. By the end of this book, you will be ready to enter the next
phase of OpenStack success by extending and customizing your private cloud based on your
requirements.
