What is Ansible?

Ansible is an open-source automation tool that simplifies the process of managing and configuring IT infrastructure. It provides a simple, yet powerful way to automate tasks, deploy applications, and manage configurations across a wide range of environments. Ansible uses a declarative language, YAML, to define the desired state of infrastructure and applications, making it easy to manage and maintain complex systems.

Main Features of Ansible

Ansible has several key features that make it a popular choice for automation and configuration management:

• Agentless Architecture: Ansible does not require any agents to be installed on the target machines, making it easy to manage infrastructure without adding additional overhead.
• Declarative Language: Ansible uses YAML to define the desired state of infrastructure and applications, making it easy to manage and maintain complex systems.
• Modular Design: Ansible has a modular design, making it easy to extend and customize the tool to meet specific needs.

Step 1: Install Ansible
