The order of resource in a Puppet manifest does not matter, except when it does. Learn how Puppet relationships like `before`, `require`, `notify`, and `subscribe` allow you to take control of how resources are loaded in your infrastructure.
At the end of this course you will be able to:
- List the 4 metaparameters used to specify resource relationships.
- Compare and contrast the differences between before and require, and between notify and subscribe.
