In the previous chapter, we talked about the provisioning of an Azure cloud infrastructure with Terraform. If this infrastructure contains virtual machines (VMs), after their provisioning, it is necessary to configure their systems and install all middleware. This configuration will be necessary for the proper functioning of the applications that will be hosted on the VM.
There are several Infrastructure as Code (IaC) tools available for configuring VMs and the best known are Ansible, Puppet, Chef, SaltStack, and PowerShell DSC. Among them, Ansible from Red Hat (https://www.ansible.com/overview/it-automation) stands out for its many assets:

- Ansible only works with one executable.
- It does not require agents installed on the VMs to be configured.
- A simple SSL/WinRM connection...
