In this chapter, we are going to be launching two Vagrant boxes so you will need Vagrant installed and access to the internet; the boxes themselves are around a 300 to 500 MB download each.
You will need to make a copy of the lemp folder from the last chapter and call it lemp-multi if you are going to follow along, adapting the roles as we work through them. If you are not following along, you can find a complete version of lemp-multi at https://github.com/PacktPublishing/Learn-Ansible/tree/master/Chapter06/lemp-multi.
