When you are using Ansible with AWS, maintaining the inventory file will be a hectic task as AWS has frequently changed IPs, autoscaling instances, and much more.
However, there is an easy solution called ansible dynamic inventory. Dynamic inventory is an ansible plugin that makes an API call to AWS to get the instance information in the run time. It gives you the ec2 instance details dynamically to manage the AWS infrastructure.
When I started using the Dynamic inventory, it was just a Python file. Later it became an Ansible plugin.
I will talk more about how to manage the AWS dynamic inventory later in this article.
Dynamic inventory is not limited to just AWS. It supports most of the public and private cloud platforms. Here is the article on managing GCP resources using Ansible Dynamic inventory.
