Learning OpenStack Networking (Neutron), Second Edition

By: James Denton

Overview of this book

OpenStack Neutron is an OpenStack component that provides networking as a service for other OpenStack services to architect networks and create virtual machines through its API. This API lets you define network connectivity in order to leverage network capabilities to cloud deployments. Through this practical book, you will build a strong foundational knowledge of Neutron, and will architect and build an OpenStack cloud using advanced networking features. We start with an introduction to OpenStack Neutron and its various components, including virtual switching, routing, FWaaS, VPNaaS, and LBaaS. You’ll also get hands-on by installing OpenStack and Neutron and its components, and use agents and plugins to orchestrate network connectivity and build a virtual switching infrastructure. Moving on, you’ll get to grips with the HA routing capabilities utilizing VRRP and distributed virtual routers in Neutron. You’ll also discover load balancing fundamentals, including the difference between nodes, pools, pool members, and virtual IPs. You’ll discover the purpose of security groups and learn how to apply the security concept to your cloud/tenant/instance. Finally, you' ll configure virtual private networks that will allow you to avoid the use of SNAT and floating IPs when connecting to remote networks.

Chapter 1. Preparing the Network for OpenStack

In today's data centers, networks are composed of more devices than ever before. Servers, switches, routers, storage systems, and security appliances now exist as virtual machines and virtual network appliances. These devices place a large strain on traditional network management systems, as they are unable to provide a scalable, automated approach to managing next-generation networks. Users now expect more control and flexibility of the infrastructure with quicker provisioning, all of which OpenStack promises to deliver.

This chapter will introduce many features that OpenStack Networking provides as well as various network architectures supported by OpenStack.
