What is Ansible?

Ansible is an open-source software tool used for automation and configuration management. It helps in deploying and managing software applications and services on multiple servers and environments. Ansible uses a simple and easy-to-learn syntax, making it a popular choice among system administrators and DevOps teams.

Main Features of Ansible

• Agentless Architecture: Ansible does not require any agents to be installed on the target servers, making it easy to manage and deploy applications.
• Playbooks: Ansible uses playbooks, which are YAML files that define the tasks to be executed on the target servers.
• Modules: Ansible has a vast collection of modules that can be used to perform various tasks, such as file management, user management, and package management.
