In this lesson, you will get a high-level overview of Ansible, a powerful automation tool. You'll understand what Ansible is, its key features, and where it fits in the world of DevOps.
What is Ansible?
Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, infrastructure orchestration, and provisioning. Automation is crucial in the world of DevOps as it enables the rapid deployment and scaling of applications and infrastructure. Ansible, developed by Red Hat, makes these automation tasks simpler and more manageable.
One of the key features of Ansible is its simplicity and ease of use. It uses a human-readable language (YAML) for its configuration files, making it accessible even to those new to automation and scripting. Ansible works by connecting to your nodes and pushing out small programs called "Ansible modules." These programs are designed to be resource models of the desired state of the system.
