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.

Shared Storage through MooseFS


MooseFS is an open source distributed file system actively developed and maintained by Gemius SA (http://www.gemius.com), a Poland-based online research agency.

Apart from the common features of distributed file systems, the usage of MooseFS with OpenNebula is encouraged due to some particular features, which are as follows:

  • Snapshots: It is possible to make real-time snapshots of directories and files.

  • Expandability: Redundancy is not defined by volume layout during creation like that of GlusterFS, but on a directory or file level. Every storage server that gets added to the cluster is automatically introduced and its space is immediately made available.

  • Automatic re-balancing: As soon as something bad happens to a storage server, missing copies are immediately replaced by new copies on remaining storage servers. If a storage server comes back online, it will get resynchronized automatically and the file copies that are in excess will be discarded.

  • Modularity:...
