To continue onto our Amazon Machine Image (AMI) building section, we cannot go any further without having a working AWS account and an associated API key so we will do that first before continuing further. To avoid ambiguity, be aware that almost all AWS services cost money to use and your use of the API may incur charges for you even for things that you might not readily expect (that is, bandwidth usage, AMI snapshot storage, and on ) so use it accordingly.
AWS is a massively complex piece of machinery, exponentially more than Ansible, and covering everything that you might need to know about it is impossible to do within the scope of this book. But we will try here to provide you with enough relevant instructions for you to have a place to start from. If you decide you want to learn more about AWS, their documentation is generally pretty great and you can find it at https://aws.amazon.com/documentation/.
