Ansible vs Ansible Tower ?

[Albert Shamsiyan]

I'm confused. From what I've understood, There are Ansible and Ansible Tower.

Ansible is for free while Ansible Tower costs. True \ False?

In case True, 

1) Where can I find comparison matrix ? \ What is the difference ?? 

2) Where to download from ?

Ansible is the command line tool that does most of the work while Ansible Tower is a web application that provides a REST API, RBAC, secure credential storage, and a scheduler (among other things) on top of Ansible the command line tool. You can't have Ansible Tower without Ansible, so comparing them directly is not quite accurate.

Thx for the reply sdoran

So using Ansible is for free and I'll licensing for using Tower for more than 10 nodes? if so, what will be the definition if node ??

Ansible Tower's upstream opensource project is called AWX.  If you don't want to pay for support you can always go AWX instead of Ansible Tower.  https://github.com/ansible/awx

A node is a host in inventory that is managed by Tower.
