To get the most out of this book

Readers should have a basic understanding of AWS, OpenStack, and CentOS.

An AWS user account is required. If you don't have a user account, ensure that you have your credit card ready in order to open a free account. (While we have taken care to use the free-tier systems in AWS, make sure that you use the appropriate instance sizes and AMI IDs if you are creating an environment in a different region.)
