In Detail

OpenStack is developed by a thriving community of individual developers around the globe and is backed by most of the leading players in the cloud space today. OpenStack is a free and open source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS).

This book begins with the design principles of OpenStack and the available OpenStack distributions. You'll start by getting a fundamental understanding of the core concepts and then move on to a comparison of OpenStack components with real-life examples. Then, we'll show you the typical architecture of OpenStack clouds, how to configure each OpenStack component, and debugging techniques.

Later, we focus on the latest releases of OpenStack: Mikata, Newton, and Ocata. You'll be introduced to identity, image, networking, and the compute service. You'll also get a complete understanding of how to install, configure, and administrate your entire virtual private cloud. You will also be provided with hands-on exercises to unleash the power of each component in OpenStack. Finally, you'll see an overview of all the optional projects available under the Openstack umbrella.

Style and approach

This fast-paced book delivers comprehensive hands-on training, so you can jump straight into the practical exercises along with in-depth coverage of OpenStack technologies. It also provides hands-on exercises, analysis of real-world cloud use cases and operation scenarios, covering design, customization and optimization.
