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 GlusterFS


GlusterFS is an open source distributed file system developed by Gluster Inc in 2005 (http://www.gluster.com) and it has been recently acquired by Red Hat in late 2011 (http://www.redhat.com/promo/storage/press-release.html).

GlusterFS features a completely decentralized architecture meaning that there is not a single point of failure and this is great for a cloud infrastructure.

In small and medium infrastructures, the GlusterFS server components could be installed directly on the OpenNebula hosts along with the hypervisor. Instead, for large deployments, it is advisable to install GlusterFS on dedicated machines and perhaps arrange them in a SAN.

GlusterFS hardware requirements

Before installing the GlusterFS, verify that your system matches the following minimum requirements:

  • CPU: An AMD 64 CPU (because i686 is not tested by Gluster developers)

  • Storage: The storage can be either local or shared as follows:

    • Direct attached storage, such as SATA, SAS, or Fibre...
