OpenNebula 3 Cloud Computing

Book Description

This book will teach you to build and maintain a cloud infrastructure using OpenNebula, one of the most advanced, highly scalable toolkits for GNU/Linux. Walks you through from initial planning to advanced management techniques.

  • 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.
