While the design of Ansible focuses on simplicity and ease of use, the architecture itself is very powerful. In this chapter, we covered key design and architecture concepts of Ansible, such as version and configuration, playbook parsing, module transport and execution, variable types and locations, and variable precedence.
You learned that playbooks contain variables and tasks. Tasks link bits of code called modules with arguments, which can be populated by variable data. These combinations are transported to selected hosts from inventory sources provided. The fundamental understanding of these building blocks is the platform on which you can build a mastery of all things Ansible!
In the next chapter, you will learn how to secure secret data while working with Ansible.
