OpenStack Overview
==================

What is OpenStack?
------------------

In CINECA, we use OpenStack to virtualize and manage cloud computing resources. `OpenStack <https://www.openstack.org/>`_
is an open-source cloud operating system that controls and manages the compute resources 
of a cloud data center.

Management Tools
----------------

To manage the resources assigned to a project, the users can 
interact with OpenStack using in-house tools like Horizon Web Dashboard and the 
Command Line Interface (CLI) or using Infrastructure as a Code tools.

Components
----------

OpenStack is a flexible tool that has a modular structure: it is split up in different 
components that can be installed and activated independently to address every user's need.
