Learning OpenStack Networking (Neutron)

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.

At this point in the installation, the OpenStack Identity, Image, Dashboard, and Compute services have been successfully deployed across the nodes of the cloud. The environment is not ready to host instances just yet, as OpenStack Networking services have not been installed or configured. If issues arise during the installation and test procedures documented throughout this chapter, be sure to check the log messages found in /var/log/nova/, /var/log/glance/, /var/log/apache2/, and /var/log/keystone/ for assistance in troubleshooting.

It is important to note that the frequent OpenStack release cycle means that older releases may no longer be available for download 12–18 months after their initial release. For updated installation guides for the latest version of OpenStack, visit

In the next chapter, we will begin the installation of Neutron networking services and discover additional information about the internal architecture of OpenStack Networking.
