OpenNebula 3 Cloud Computing

Overview of this book

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.

OCCI Interface


Along with the EC2 Query interface, OpenNebula natively includes a second remote interface, called OCCI.

The Open Cloud Computing Interface (OCCI) is a RESTful protocol, and a comprehensive API for managing cloud resources. Unlike the Amazon EC2 Query interface, OCCI is being developed through the Open Grid Forum (http://www.ogf.org/), which actually maintains a lot of standards, mainly for the Grid interoperability environments (http://en.wikipedia.org/wiki/Open_Grid_Forum#Standards).

If you do not need EC2 compatibility, or if you are starting from scratch in developing ad-hoc integrations with OpenNebula, using the OCCI interface is highly recommended for its openness.

Like the EC2 Query interface, the OCCI service is implemented upon the OpenNebula Cloud API (OCA) and Sinatra, a widely used lightweight Ruby web framework.

The OCCI interface included in the OpenNebula 3.x distribution does not implement the latest OCCI specification, but it is based on the draft 0.8 of the...
