Overview of this book

<p>Chef is a configuration management tool that turns IT infrastructure into code. Chef provides tools to manage systems at scale. With this book, you will learn how to use the same tools that companies such as Facebook, Riot Games, and Ancestry.com use to manage and scale their infrastructure.</p> <p>This book takes you on a comprehensive tour of Chef's functionality, ranging from its core features to advanced development. You will be brought up to speed with what's new in Chef and how to set up your own Chef infrastructure for individuals, or small or large teams. Once you have the core components, you will get to grips with bootstrapping hosts to then develop and apply cookbooks. If you want to fully leverage Chef, this book will show you advanced recipes to help you handle new types of data providers and resources. By the end of this book, you will be confident in how to manage your infrastructure, scale using the cloud, and extend the built-in functionality of Chef itself.</p>

Summary


Now that you've learned the key terminology that Chef uses and dissected an example infrastructure a bit, you can see the following:

  • Infrastructure can be decomposed into the various roles that resources (nodes) play within that infrastructure

  • A combination of recipes and configuration data provide us with roles that describe a part of our overall infrastructure

  • Chef analyzes the roles applied to hardware resources (nodes) and generates a run list that is specific to the node that those roles are being applied to

  • A run list is then combined with the cookbooks, recipes, templates, and configuration data to build a specific set of scripts that are executed on the node when the chef-client is run

  • We can apply these methodologies of automated configuration to cloud servers and physical systems alike.

Now that you understand how Chef models interact, let's take a look at how we can get started with cloud services using Chef.
