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.

About the Author
About the Reviewers


OpenStack Networking offers the ability to create and manage different technologies found in a data center in a virtualized and programmable manner. If the built-in features and reference implementations are not enough, the pluggable architecture of OpenStack Networking allows for additional functionality to be provided by third-party commercial and open-source vendors. The security requirements of the organization building the cloud as well as the use cases of the cloud will ultimately dictate the physical layout and separation of services across the infrastructure nodes.

Throughout this book, you will learn how to build a functional OpenStack cloud utilizing advanced Neutron networking features available as of the Kilo release. In the next chapter, we will begin a package-based installation of OpenStack on the Ubuntu 14.04 LTS operating system. Topics covered include the installation, configuration, and verification of the database; messaging; and OpenStack identity, image, compute, and dashboard services. The installation and configuration of base OpenStack Networking services, including the Neutron API, can be found in Chapter 3, Installing Neutron.
