The main idea behind this post is the wish of getting a configured SharePoint farm which has friendly and standardized names for the databases created during the configuration process.
Below I will post only the PowerShell scripts that I used to provision the services that don’t offer the possibility of configuring the database name(s).

Central Administration Provisioning
The following script provisions the central administration. Run it on the first SharePoint server within your farm, on the server that is going to host the Central Administration web application.
