Overview of this book

This is the fourth edition of the industry-acclaimed OpenStack Cloud Computing Cookbook, created by four recognized OpenStack experts. It has now been updated to work with the latest OpenStack builds, using tools and processes based on their collective and vast OpenStack experience. OpenStack Open Source Cloud software is one of the most used cloud infrastructures to support a wide variety of use cases, from software development to big data analysis. It is developed by a thriving community of individual developers from around the globe and backed by most of the leading players in the cloud space today. We make it simple to implement, massively scalable, and able to store a large pool of data and networking resources. OpenStack has a strong ecosystem that helps you provision your cloud storage needs. Add OpenStack's enterprise features to reduce the cost of your business. This book will begin by showing you the steps to build up an OpenStack private cloud environment using Ansible. You'll then discover the uses of cloud services such as the identity service, image service, and compute service. You'll dive into Neutron, the OpenStack Networking service, and get your hands dirty with configuring networks, routers, load balancers, and more. You’ll then gather more expert knowledge on OpenStack cloud computing by managing your cloud's security and migration. After that, we delve into OpenStack Object storage and you’ll see how to manage servers and work with objects, cluster, and storage functionalities. Finally, you will learn about OpenStack dashboard, Ansible, Keystone, and other interesting topics.

Introduction to OpenStack networking


Networking in OpenStack is provided by a project that goes by the name of Neutron. Neutron is an API-driven system that manages physical and virtual networking resources in an OpenStack cloud. Operators and users can leverage the Neutron API to build rich network architectures that best suit the requirements of their applications.

Neutron utilizes a pluggable and extensible architecture that allows developers to write robust drivers that implement and configure virtual and physical network resources, including switches, routers, firewalls, and load balancers. Neutron is composed of an API server and various agents that are responsible for implementing the virtual network architected by users. The following diagram demonstrates how the Neutron API server interacts with various plugins and agents to construct networking in the cloud:
