Set up, manage, and maintain your cloud and learn solutions for datacenter virtualization with this step-by-step practical guide
- Take advantage of open source distributed file-systems for storage scalability and high-availability
- Build-up, manage and maintain your Cloud without previous knowledge of virtualization and cloud computing
- Install and configure every supported hypervisor: KVM, Xen, VMware
- Step-by-step, focused on Ubuntu/Debian distributions, but with general how-to working with every GNU/Linux distribution
In Detail
OpenNebula is one of the most advanced and highly-scalable open source cloud computing toolkits. If you ever wanted to understand what Cloud Computing is and how to realize it, or if you need a handy way to manage your messy infrastructure in a simple and coherent manner, this is your way.
OpenNebula 3 Cloud Computing guides you along the building and maintenance of your cloud infrastructure, providing real-world examples, step-by-step configuration and other critical information. The book keeps you a step ahead in dealing with the demanding nature of cloud computing and virtual infrastructure management using one of the most advanced cloud computing toolkits OpenNebula. The book takes you from a basic knowledge of OpenNebula to expert understanding of the most advanced features.
The book starts with a basic planning of hardware resources and presents the unique benefits of the supported hypervisors; you will go in deep with day-to-day management of virtual instances, infrastructure monitoring and integration with Public Clouds like Amazon EC2.
With this book you will be able to get started with fast and cheap configuration recipes, but also go deeper for a correct integration with your existing infrastructure.
You will deal with well-know virtualization technologies like Xen and VMware, but also with the promising KVM technology integrated in the Linux kernel. After the basic infrastructure set-up, you will learn how to create and manage virtual instance via both command-line and web interfaces, and how to monitor your existing resources.
At the end, the book acquaints you with integrating your local infrastructure with external Cloud resources but also publishing your resources to others via common API interfaces.
What you will learn from this book
- Plan your hardware infrastructure and keep resources and hardware under monitoring
- Install OpenNebula, from sources or binary distribution and configure it on your front-end host
- Install and configure KVM, Xen and VMware ESXi on your hosts, building from sources when needed
- Integrate with existing NAS/SAN infrastructure or provide flexible and scalable storage with distributed file-systems
- Manage your day to day virtual instances via both command-line and web interfaces
- Monitor your infrastructure continuously using OpenNebula
- Extend your cloud with resources from remote Cloud providers using standard API interface
- Provide Cloud resources to external facilities through standardized API interfaces
Approach
This is a step-by-step practical guide to get you started easily with openNebula. It guides you to build, maintain, and configure your cloud infrastructure, providing real-world examples in a simple and coherent manner.
Who this book is written for
If you are a GNU/Linux system administrator with no experience with virtualization or cloud computing but eager to learn about it, or you are thwarted by your current virtualized infrastructure, this book is for you. You are expected to have some basic knowledge of GNU/Linux, with knowledge of basic package management tools and system configuration.

It is a pleasure to write the foreword to a book which will guide you through the basics and internals of OpenNebula. In a world where the term Cloud Computing is clearly abused and overloaded, this book will be a valuable reference to both newcomers and Cloud professionals. The main steps to build Cloud infrastructures of any type, from public or hybrid to private clouds are described in this book in a practical, clear, and effective way using OpenNebula.
It is almost seven years since the first versions of OpenNebula were released in an embryonary phase as a University project, gathering the outcomes of our research in distributed Cloud infrastructures. OpenNebula by design is very light (in terms of its dependencies and components), and easy to extend and adapt. Its simple and quite effective design has proven (and is accepted) to be very scalable and "hackable" leading to flexible and agile Cloud deployments all around the world.
Since its first software release in March 2008, OpenNebula has evolved into an active open source project with an engaged community of users and developers that by many measures, is more than doubling each year. We are really excited with the wide adoption of the software, being downloaded several thousands times per month from our site, and being used in several very large scale deployments.
And now, you have the book in your hands. Giovanni has been a long-time contributor to OpenNebula in multiple and valuable forms. This book is just another great contribution from him, a must-have for every OpenNebula practitioner as well as a very interesting reference for anybody looking for hands-on knowledge in Cloud Computing. Thanks Giovanni for your valuable contributions!
OpenNebula could be difficult sometimes, but it provides you with a powerful and flexible technology. This book is your first step to master it.

Giovanni Toraldo started to mess with Linux and free software during his early years at school, developing hobbyist websites with free CMS and maintaining the official Italian support site of PHP-Fusion. After a few unsatisfactory years at university, he decided to start working as a System Administrator and Web Developer at LiberSoft (http://www.libersoft.it), a start-up based in a technology park near Pisa (http://www.polotecnologico.it/). Nowadays, he has developed skills in designing and maintaining Open Source virtualization and clustering solutions, managing tens of hosts, servicing hundreds of requests mainly web hosting stacks for Drupal and Symfony webapps.
I would like to thank everyone who participated on this project, especially LiberSoft, for sponsoring the hardware with which I tested the OpenNebula configurations.
Benot Benedetti works as a Linux System Administrator, for the University of Nice Sophia Antipolis, where he graduated with a degree in computer science.
Before coming back to the university as a sysadmin, he worked for various companies ranging from banks to hosting providers, where he had to deal with different operating systems, but always promoted the use of open source software and Linux.
He is interested in resolving new problems, as it is always an opportunity to work on new technologies. Benot loves helping users, teaching students, and he occasionally writes technical articles for French Linux magazines.
I would like to thank every person who dedicates his/her time to developing free and open source software, and making them available for us to play with.
Many thanks to the author and the entire staff at Packt Publishing, they helped me to be as efficient as possible as a Technical Reviewer.
Last but not the least, I would like to dedicate all my accomplishments to my parents for their hope, patience, and support.
Nick Zhu is a professional Software Development Consultant and a journeyman Software Craftsman living and working in Greater Toronto, Canada. In his spare time he is an active open source contributor, and a Pragmatic and Agile advocate.
