Before using the module you need to collect all the information regarding your infrastructure:
* hostnames
* networks (admin, management, data, etc.)
* Network devices
* other specific settings
The first step in using the iaas module is to configure Hiera with the specific settings of your infrastructure.
You can find in the `examples/` directory a sample 'common.yaml' file with all of the settings required by the module.

### Site configuration
The second step is to configure the manifest file with specific settings pointing to your installation.
In this module, the `examples` directory contains a sample 'site.pp' file that can be updated according to your deployment.
In this module, the `examples/` directory contains a sample 'site.pp' file that can be updated according to your deployment.
The configuration options present in this file include Service variables and node-specific configuration settings.
If any of these settings are undefined or not properly set, your deployment may fail.
### Nodes balancing
In order to balance requests across the different nodes, HAproxy and Keepalived have to be configured properly.
Make sure also that nodes hostnames con be easily resolved to the corresponding IPs, both direct and reverse.
