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.

Neutron plugins reference

Implementing a custom network layout in an OpenStack environment can be achieved by acquiring the usage of plugins within the Neutron architecture. It is important to differentiate between two types of plugins in Neutron as follows:

  • Core plugins: These enable layer 2 connectivity, IP addressing management, and orchestration of the logical elements of a virtual network, including networks, ports, and subnets.
  • Service plugins: These enable a higher implementation of network services at layer 3 including routings, load balancing, firewalling, and VPN services.

By exploiting the plugin-based architecture design of Neutron, a cloud administrator can go beyond basic network implementations and extend its layout to support additional network functionalities.

Before diving into this exercise, let's have a look at the current state of art of the new Neutron...
