Discover the basics of virtual networking in OpenStack to implement various cloud network architecturesKey FeaturesLearn the difference between Open vSwitch and Linux bridge switching technologiesConnect virtual machine instances to virtual networks, subnets, and portsImplement virtual load balancers, firewalls, and routers in your networkBook DescriptionOpenStack 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.What you will learnGet familiar with Neutron constructs, including agents and pluginsBuild foundational Neutron resources to provide connectivity to instancesWork with legacy Neutron routers and troubleshoot traffic through themExplore high-availability routing capabilities utilizing Virtual Router Redundancy Protocol (VRRP)Create and manage load balancers and associated componentsManage security groups as a method of securing traffic to and from instancesWho this book is forIf you are an OpenStack-based cloud operator and administrator who is new to Neutron networking and wants to build your very own OpenStack cloud, then this book is for you.Prior networking experience and a physical server and network infrastructure is recommended to follow along with concepts demonstrated in the book.
