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>

This is outside the scope of this book, but it would be something to make sure you configure for production systems, as you probably do not want the public on the Internet to have direct access to your database server.

And to provision the web server, we will use the following command:
