What is Ansible?

Ansible is an open-source automation tool that simplifies the process of managing and configuring computer systems, networks, and applications. It is designed to be efficient, reliable, and easy to use, making it an ideal choice for DevOps teams and system administrators. Ansible uses a simple, human-readable language called YAML to define tasks, known as “playbooks,” which can be used to automate a wide range of tasks, from deploying software to managing infrastructure.

Main Features of Ansible

Agentless Architecture

Ansible’s agentless architecture means that there is no need to install any software on the machines being managed. Instead, Ansible uses SSH or WinRM to connect to the machines and execute tasks.

Playbooks

Playbooks are the core of Ansible’s automation capabilities. They are written in YAML and define a series of tasks that can be executed on one or more machines.

Modules

Ansible has a vast library of modules that can be used to perform specific tasks, such as managing users, installing software, and configuring networks.
