Playbooks
Ansible playbooks are a key feature of the tool. Playbooks are text files that define the desired state of the infrastructure and the steps needed to achieve that state. Playbooks are easy to read and write, and can be reused across multiple environments.
Modules
Ansible modules are small pieces of code that perform specific tasks, such as installing software or configuring network devices. Ansible provides a large collection of pre-built modules, and users can also create their own custom modules.
