Key FeaturesBook DescriptionIf you are an OpenStack-based cloud operator with experience in OpenStack Compute and nova-network but are new to Neutron networking, then this book is for you. Some networking experience is recommended, and a physical network infrastructure is required to provide connectivity to instances and other network resources configured in the book.What you will learnWho this book is for

Build and manage networks in OpenStack using Neutron

About This Book

Deploy an all-in-one cloud based on OpenStack Liberty (2015.2) using RDOLearn the fundamentals of the Neutron API including networks, subnets, and ports, and how to manage these resources in the cloudBuild simple virtual network infrastructures in the cloud

Who This Book Is For

The book is for those who are new to OpenStack and Neutron who want to learn the cloud networking fundamentals and get started with OpenStack networking. Prior networking experience along with a virtual or physical server is recommended to follow along with the concepts demonstrated in the book.

What You Will Learn

Install the latest Liberty (2015.2) release of OpenStack using RDO in VirtualBoxDiscover the basics of the Neutron API, including networks, subnets, and portsInteract with Neutron using the CLI and Horizon dashboardCreate networks and subnets that provide connectivity to instancesImplement software routers that connect networks and provide network address translationSecure instances using Neutron''s security group functionality

In Detail

The OpenStack Networking API offers users the ability to create and manage both basic and complex network architectures that blend the virtual and physical network infrastructure.

This book kicks off by describing various components of Openstack Neutron and installing Ubuntu OpenStack based on Canonical''s process. Further on, you will use various methods to interface with Neutron to create and manage network resources. You will also get to grips with the relationship between ports, networks, and subnets through diagrams and explanations, and see how the logical components are implemented via plugins and agents.

Moving forward, you will learn how virtual switches are implemented and how to build Neutron routers. You will also configure networks, subnets, and routers to provide connectivity to instances using simple examples. At the end, you will configure and manage security groups, and will observe how these rules translate to iptables rules on the host machines.

By the end of the book, you will be able to build basic network architectures using Neutron networks and routers in no time.

Style and approach

An easy-to-follow guide that covers the networking features of OpenStack and the core Neutron API components providing a solid foundation to deploy networks and instances.

Wield the power of OpenStack Neutron networking to bring network infrastructure and capabilities to your cloud Key FeaturesThis completely up-to-date edition will show you how to deploy a cloud on OpenStack using community-driven processes. It includes rich examples that will help you understand complex networking topics with ease.Understand every aspect of designing, creating, customizing, and maintaining the core network foundation of an OpenStack cloud using OpenStack Neutron all in one book.Written by best-selling author James Denton, who has more than 15 years of experience in system administration and networking. James has experience of deploying, operating, and maintaining OpenStack clouds and has worked with top enterprises and organizations.Book DescriptionOpenStack 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.What you will learnArchitect and install the latest release of OpenStack on Ubuntu Linux 14.04 LTSReview the components of OpenStack networking, including plugins, agents, and services, and learn how they work together to coordinate network operationsBuild a virtual switching infrastructure using reference architectures based on ML2 + Open vSwitch or ML2 + LinuxBridgeCreate networks, subnets, and routers that connect virtual machine instances to the networkDeploy highly available routers using DVR or VRRP-based methodsScale your application with haproxy and Load Balancing as-a-ServiceImplement port and router-level security using Security Groups and Firewall as-a-ServiceProvide connectivity to tenant networks with Virtual Private Networking as-a-Service (VPNaaS)Find out how to manage OpenStack networking resources using CLI and GUI-driven methodsWho 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.

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.
