Configuration management plays a pivotal role in maintaining a stable and organized IT infrastructure by enabling the systematic gathering of information from remote hosts, facilitating server provisioning, and streamlining application upgrades or deployments.

You will learn the core features of Ansible, such as inventory, variables, playbooks, roles, and handlers, which serve as the building blocks for configuration management. You will learn how to write playbooks that define and execute complex orchestration tasks with ease. Next, you’ll learn how to use roles to maintain consistency across configuration management projects and how to harness the power of Jinja2 to apply logic and control structures and generate configuration files dynamically.

After completing this course, you will be equipped with the necessary skills for customizing configurations, organizing automation tasks efficiently, and maintaining a desired state for your infrastructure.
