OpenStack Networking Essentials

By: James Denton, Derek Chamorro

Overview of this book

The OpenStack Networking API offers users the ability to create and manage both basic and complex network architectures that blend the virtual and physical network infrastructure. This book kicks off by describing various components of Openstack Neutron and installing Ubuntu OpenStack based on Canonical's process. Further on, you will use various methods to interface with Neutron to create and manage network resources. You will also get to grips with the relationship between ports, networks, and subnets through diagrams and explanations, and see how the logical components are implemented via plugins and agents. Moving forward, you will learn how virtual switches are implemented and how to build Neutron routers. You will also configure networks, subnets, and routers to provide connectivity to instances using simple examples. At the end, you will configure and manage security groups, and will observe how these rules translate to iptables rules on the host machines. By the end of the book, you will be able to build basic network architectures using Neutron networks and routers in no time.

Summary


Neutron is one of the more complicated OpenStack components to configure and maintain, and the list of features in this chapter is by no means comprehensive. The payoff of Neutron's complexity is that users are able to programmatically build elaborate and consistent network topologies. Neutron provides reference implementations using open source components for all of the features it supports, and its extensible framework allows third parties to build plugins and drivers that can interface with other virtual and physical network devices in order to bring additional features and functionality to the cloud. To successfully deploy Neutron and harness all it has to offer, it is important to have a strong understanding of core networking concepts. In this book, we will cover some fundamental network concepts of Neutron and build a foundation for deploying instances.

In the next chapter, we will use the RDO OpenStack distribution and its included installer to configure an all-in-one deployment that will enable us to explore virtual switching and routing concepts in further detail.
