Learning OpenStack Networking - Third Edition

By: James Denton

Overview of this book

OpenStack Networking is a pluggable, scalable, and API-driven system to manage physical and virtual networking resources in an OpenStack-based cloud. Like other core OpenStack components, OpenStack Networking can be used by administrators and users to increase the value and maximize the use of existing datacenter resources. This third edition of Learning OpenStack Networking walks you through the installation of OpenStack and provides you with a foundation that can be used to build a scalable and production-ready OpenStack cloud. In the initial chapters, you will review the physical network requirements and architectures necessary for an OpenStack environment that provide core cloud functionality. Then, you’ll move through the installation of the new release of OpenStack using packages from the Ubuntu repository. An overview of Neutron networking foundational concepts, including networks, subnets, and ports will segue into advanced topics such as security groups, distributed virtual routers, virtual load balancers, and VLAN tagging within instances. By the end of this book, you will have built a network infrastructure for your cloud using OpenStack Neutron.

Summary

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.

To successfully deploy Neutron and harness all it has to offer, it is important to have a strong understanding of core networking concepts. In this book, we will cover some fundamental network concepts around Neutron and build a foundation for deploying instances.

In the next chapter, we will begin a package-based installation of OpenStack on the Ubuntu 16.04 LTS operating system. Topics covered include the installation, configuration, and verification of many core OpenStack projects, including Identity, Image, Dashboard, and Compute. The installation and configuration of base OpenStack Networking services, including the Neutron API, can be found in Chapter 3, Installing Neutron.
