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.

Introduction to OpenStack Networking

In today's data centers, networks are composed of more devices than ever before. Servers, switches, routers, storage systems, and security appliances that once consumed rows and rows of data center space 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 and 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. Some topics that will be covered include the following:

  • Features of OpenStack Networking
  • Physical infrastructure requirements
  • Service separation
