Why using Ansible ? • Chef without having to write Ruby! • Puppet/Salt without masters, minions, manifests, certs..! • Diversity of Ansible modules 

Task • It's a unit action that set the state of a system! • Code that is remotely executed with arguments • Directory should exist! • Service should run! • Package should be installed! • Files should be present 

Task • Should be idempotent! • Can use conditionals! • Can use variables! • Use Ansible modules 

Playbook Ordered set of tasks • Bundle of several tasks! • Set the variable values for the tasks! • Defines which host the bundle of tasks should be applied to. 

Playbook • Tasks are executed synchronously! • In parallel across hosts! • Execution moves on until all tasks complete or all hosts have failed
