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 toolkitsñ 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.

If you plan to use a dedicated installation (maybe inside a VM instance running on one of the managed OpenNebula clusters) rather than on one of the available OpenNebula frontends, you can install only the oZones components by passing the -o parameter to the install.sh script from the sources package. Don't forget to run the install_gems script!

The ozone-server component will permit us to define new zones and VDCs, and manage them from a bird's eye view with the integrated web GUI and CLI. Also, a .htaccess file will be automatically generated to configure a local running Apache server to act as a proxy to hide the VDC details to end users.

Configuring the Apache2 reverse-proxy

In the early chapters, we used nginx as a SSL proxy for the Sunstone interface as it is more lightweight than a full-fledged...
