Preface

As DevOps and platform engineering have pushed demand for powerful internal development platforms, the need for infrastructure automation solutions has never been greater. Puppet is one of the most powerful infrastructure automation solutions used by the largest enterprises in the world and has a strong open source community. This book comprehensively explains both the Puppet language and the platform. Starting with the basic concepts and approach of how Puppet works as a stateful language, it builds up to explaining how to structure Puppet code to scale and allow flexibility and collaboration among teams. It then looks at how the Puppet platform allows management and reporting of infrastructure configuration, showing how the platform can be integrated with other tools such as ServiceNow and Splunk. Finally, approaches will be discussed to understand how to implement Puppet to fit into heavily regulated and audited environments as well as modern hybrid cloud environments.

By the end of this book, you will have a full understanding of the capabilities of both the Puppet language and platform and be able to structure and scale Puppet to create a platform to provide enterprise-grade infrastructure automation.
