Postulating the OpenStack setup

OpenStack, as a distributed system, is designed to facilitate the designing of your private cloud. As summed up in the previous section, many components can run across different fleets of nodes. When it comes to a large infrastructure, the OpenStack setup can scale to more than one location, forming multisite environments that are geographically dispersed. In order to manage large-scale infrastructure with OpenStack, it becomes crucial to find a promising approach that makes any deployment, change, or update of the underlying infrastructure more consistent and easy to operate.

A very new and promising approach that will transform the way of managing IT infrastructures is IaC. Covering the challenges and principles of such model could fill an entire book. In the next section, we will cover how we will deploy our OpenStack environment on a large scale by adopting such an approach.
