Ansible part 1

##############Ansible ###############
play book is composed of 1 or more plays in a list
The goal of a play is to map a group of hosts to some well defined roles, represented by things ansible calls tasks. At a basic level, a task is nothing more than a call to an ansible module, which you should have learned about in earlier chapters.
