What is Ansible?

Ansible is an open-source automation tool that helps IT professionals manage and automate their infrastructure, applications, and services. It provides a simple and efficient way to automate repetitive tasks, deploy software, and configure systems. Ansible uses a declarative configuration model, which means that users define the desired state of their infrastructure, and Ansible takes care of the rest.

Main Features

Ansible has several key features that make it a popular choice among IT professionals. Some of the main features include:

• Agentless Architecture: Ansible does not require any agents to be installed on the target machines, making it a lightweight and easy-to-use solution.
• Declarative Configuration Model: Ansible uses a declarative configuration model, which means that users define the desired state of their infrastructure, and Ansible takes care of the rest.
• Playbooks: Ansible playbooks are YAML files that define the automation tasks and workflows. They are easy to read and write, and can be reused across different environments.
