It is agent-less - you have to verify your environment consistency 'on-demand' - there is no built-in mechanism taht would warn you about some change automatically (this can be achieved with reasonable effort - but it must be known) It is agent-less - you have to verify your environment consistency 'on-demand' - there is no built-in mechanism taht would warn you about some change automatically (this can be achieved with reasonable effort - but it must be known)
Official GUI Tool (web inferface) - Ansible Tower - is great, but it is expensive. There is no 'small enterprice' payment plan. Easy workaround with Rundeck or Jenkins is possible with reasonable workload. Official GUI Tool (web inferface) - Ansible Tower - is great, but it is expensive.

It is very-very-very easy to start. If you are familiar with ssh concept - you already know ansible (ALMOST). My personal record is: 'I did show how to install and use ansible (for simple raspberry pi cluster management) and it tool me 30 seconds to deliver a working tool !!!)'

In the 'low-level' way you can use it to execute remote command in more controlled way (still using ssh). In the 'low-level' way you can use it to execute remote command in more controlled way (still using ssh).
On the other hand - in advanced scope - you can use python anible code as a library to your own python scrips! This is awesome! (if you know what you are doing). It is a bit like fabric then.

But ansible is way more! It provides an execution plans, an API, library, callbacks, not forget to mention - COMUNITY! and great support by developers! But ansible is way more!
