Extending OpenStack

By: Omar Khedher

Overview of this book

OpenStack is a very popular cloud computing platform that has enabled several organizations during the last few years to successfully implement their Infrastructure as a Service (IaaS) platforms. This book will guide you through new features of the latest OpenStack releases and how to bring them into production straightaway in an agile way. It starts by showing you how to expand your current OpenStack setup and how to approach your next OpenStack Data Center generation deployment. You will discover how to extend your storage and network capacity and also take advantage of containerization technology such as Docker and Kubernetes in OpenStack. Additionally, you'll explore the power of big data as a Service terminology implemented in OpenStack by integrating the Sahara project. This book will teach you how to build Hadoop clusters and launch jobs in a very simple way. Then you'll automate and deploy applications on top of OpenStack. You will discover how to write your own plugin in the Murano project. The final part of the book will go through best practices for security such as identity, access management, and authentication exposed by Keystone in OpenStack. By the end of this book, you will be ready to extend and customize your private cloud based on your requirements.

Varying the block storage backends

The block storage service in OpenStack , code named Cinder, has been extensively developed at every OpenStack release to come with new additions to support multiple storage vendors. As Cinder has become the default service for persistent storage in OpenStack, managing volumes for virtual machines has been simplified. This covers more operational commands for different use cases, including:

  • Recovering instances due to hypervisor failure or instance termination events by attaching volumes to new ones.
  • Resizing volumes size based on storage array capacity and flavor needs.
  • Storage backup enhanced by the volume snapshot option.
  • Creating volumes from snapshots.
  • Enhanced block storage capabilities including quality of service, live migration, and performance requirements such as latency and input/output storage throughput. This can be adjusted depending...
