Ansible

What is Ansible?

The configuration management system is designed to make it easy for administrators and operations teams to control multiple servers. They allow you to control many different systems in one automated way from a central location. Linux systems have many common configuration management systems, such as Chef and Puppet, but these systems are more complex than many people want or need. Ansible is a great alternative to these options because the overhead is much less.

Ansible works by configuring a client computer from a computer that installs and configures the Ansible component. It communicates over a normal SSH channel to get information from remote computers, issue commands, and copy files. Therefore, on the Ansible system, there is no need to install additional software on the client's computer. This is one of Ansible's ways to simplify server management. Servers with open SSH ports can be placed under Ansible's configuration umbrella, regardless of the stage of their lifecycle.

Ansible's modular approach uses the capabilities of the main system to easily handle specific scenarios. Modules can be written in any language and can communicate using standard JSON. Profiles are primarily written in YAML data serialization format because they have expressiveness and similarity to common markup languages. Ansible can interact with the client through its command-line tool or its configuration script called Playbook.
