# Host Groups

## Requirements

Linux Control Center = 2.10.X or Higher

## Overview

The main objective of the Linux Control Center (LCC) is to facilitate the administration of Linux hosts. To this end, the LCC offers the ability to create host groups, allowing the execution of several actions simultaneously on a large number of hosts, optimizing the management of the environment.

## Objective

This manual aims to demonstrate how to create groups and insert hosts to manage them through LCC Actions.
