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.

Chapter 3. Installing Neutron

OpenStack Networking, also known as Neutron, provides a network Infrastructure as a Server (IaaS) platform to users of the cloud. In the last chapter, we installed some of the base services of OpenStack, including Keystone, Glance, and Nova. In this chapter, I will guide you through the installation of Neutron networking services on top of the OpenStack environment installed in the previous chapter.

Components to be installed include:

  • Neutron API server

  • Modular Layer 2 (ML2) plugin

  • DHCP agent

  • Metadata agent

By the end of this chapter, you will have a basic understanding of the function and operation of various Neutron plugins and agents, as well as a foundation on top of which a virtual switching infrastructure can be built.
