What is Ansible?
Ansible is an open-source automation tool that helps users automate their IT tasks, such as deployment, configuration management, and orchestration. It uses a simple, agentless architecture that is easy to learn and use. Ansible is widely used in enterprise environments to automate tasks, such as provisioning, patching, and compliance checking.

- Agentless Architecture: Ansible does not require any agents to be installed on the target machines, making it easy to use and manage.
- Playbooks: Ansible uses playbooks, which are YAML files that define the automation tasks to be performed.
- Modules: Ansible has a large collection of modules that can be used to perform various tasks, such as file management, user management, and network management.
