Needs advice

I was in a situation where I have to configure 40 RHEL servers 20 each for Apache HTTP Server and Tomcat server. My task was to

configure LVM with required logical volumes, format and mount for HTTP and Tomcat servers accordingly.
Install apache and tomcat.
Generate and apply selfsigned certs to http server.
Modify default ports on Tomcat to different ports.
Create users on RHEL for application support team.
other administrative tasks like, start, stop and restart HTTP and Tomcat services.

I have utilized the power of ansible for all these tasks, which made it easy and manageable.
