In Chapter 2, Organizing Your Nodes and Data, we showed you how to organize your nodes using an ENC or Hiera, or ideally both. At that point, we didn't cover the Forge modules or writing your own modules, as we did in Chapter 4, Public Modules, and Chapter 5, Custom Facts and Modules. In this chapter, we will cover a popular design concept employed in large installations of Puppet. The idea was originally made popular by Craig Dunn in his blog, which can be found at http://www.craigdunn.org/2012/05/239/. Garry Larizza also wrote a useful post on the subject at http://garylarizza.com/blog/2014/02/17/puppet-workflow-part-2/.

It will show you how to fit Puppet into your enterprise and allow many developers to work on your Puppet code simultaneously. In addition, you will learn to write custom facts and roll your own modules to solve problems. Next, popular options for performing reporting and orchestration tasks will be introduced in this book. Moving over to troubleshooting techniques, which will be very useful. The concepts presented are useful to any size organization.
By the end of the book, you will know how to deal with problems of scale and exceptions in your code, automate workflows, and support multiple developers working simultaneously.
