For those of you who have not started looking at Ansible and do not see the benefit of Ansible. Already if you have one job that you will do on several machines, you benefit from starting to look at Ansible, even if it is different job each time. Once you set up Ansible, you start saving TIME. It is possible to expand the use of Ansible all the time. It may feel difficult to get started but I can guarantee when it is up and running you will just want to do more things in Ansible.
Here is a link to how to install Ansible:
Installing Ansible — Ansible Documentation
Here is also a quick link to what opportunities you have to do with Ansible for IBMi:

Here’s a job I usually get to do a couple of times a week: rename files, FTP files to the systems and edit in a .ini file, restart subsystems. It took about 30-40 minutes per machine if everything went smoothly. Now it takes 30 seconds and really not much slows down if I run all the machines at once max 5 minutes so I have free done about 17 hours of my work week to do other more fun things on.

So if you calculate how long a job takes and then multiply it by the number of environments you have. Then imagine how much time you save on running it with Ansible and knowing that all machines get the same (the risk of making errors is minimal if you have tested and checked that everything is correct).
It will be a lot of time in the end.
