What is the main function of the Ansible tool in configuration management and infrastructure automation?

The main function of Ansible is automation of configuration management and infrastructure deployment. Ansible allows describing the state of servers and applications using simple declarative scripts (playbooks), which are then automatically applied to target systems.

Key features of Ansible:

• Automatic deployment of applications and services.
• Configuration management of servers (installing packages, configuring services).
• Orchestration of complex multi-step processes.
• Ensuring repeatability and consistency of infrastructure.

An example of a simple playbook for installing nginx:

- hosts: webservers
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present

Thus, Ansible simplifies and speeds up infrastructure management processes, reducing manual operations and errors.
