Pros:

reproducible environments
easy to begin with
fast deployment
scalable

Cons:

small time investment to learn it

In a nutshell

A Control Node executes tasks, defined in playbooks on Managed Nodes over SSH or API's
Control Node: This can be any linux based host (or windows with wsl) where ansible is installed and is connected to the same network as the Managed Nodes
Managed Node: Any device that should be managed or setup
playbook.yml: A yml file that contains the involved hosts, process and tasks that should be done
inventory.yml: A yml file that contains all hosts, grouped in sections if needed (e.g. different branches, locations, device/os types)

Install Ansible

https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

Linux

sudo apt install ansible

Windows

install wsl first
https://learn.microsoft.com/en-us/windows/wsl/install
run in Terminal wsl --install

Execute Playbooks

example with a playbook named playbook-example.yml and inventory.yml
ansible-playbook -i inventory.yml playbook-example.yml -kK
-K if become/sudo is needed
-k for user/password based authentication

Repository

some easy scripts
