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


In this chapter, we looked at the basics of the Neutron API and its data model, made up of networks, subnets, and ports. Those objects were used to describe in a logical way how the virtual network is architected and implemented across the cloud. Now that we've covered the fundamentals, let's take a look at the various ways in which users can interface with Neutron. In the next chapter, we will explore the use of the Neutron CLI client and Horizon dashboard to create and manage Neutron resources.
