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.

Maximizing network availability

The ML2 plugin offers a wide range of possibilities to handle different virtual network topologies in an OpenStack environment. The implementation of virtual networks can be more complex, depending on how traffic will be segmented based on tunneling.

Tunneling in OpenStack networking jargon can be classified into two network types:
  • Underlay network: IP fabric network connectivity between network and compute nodes
  • Overlay network: A virtual layer-2 domain for connectivity between VMs

Depending on which mechanism driver is being used, any virtual network in Neutron acts as a layer-2 broadcast domain. To manage and operate any type of virtual network resources, refer to the basic pieces in Neutron forming a virtual network infrastructure as follows:

  • Virtual network switches: These connect virtual and physical networks by the means of virtual ports...
