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.

OpenStack is chosen as a platform for many reasons, but one that frequently tops the list is orchestration. Without an element of orchestration in your OpenStack environment, you have a powerful turbo engine car that is just used for the school-run. As with any cloud environment, there are various tools to help with your orchestrated workloads, but out of the box, OpenStack provides Heat, the orchestration engine.

With Heat, you can define rich environments in a template, such as a multi-tier web application, which allows users consistency in launching these relatively complex deployments. I view the Heat orchestration templates (known as HOT (Heat Orchestration Template) – get it?) as a recipe that is written in YAML (Yet Another Markup Language). You define your ingredients that make up the environment. In a cooking recipe, this would be listing the amount of chocolate, flour, and sugar that is required for something like a cake. In a HOT ()file...
