Used us-east-2 instance ami id. So defaulted the region with us-east-2
I haven't used ansible since I used terraform itself to deploy the setup. Since I am using simple busybox for http with ubuntu I don't need to make it complicated. Also I felt when the need is fulfilled in terraform I haven't used Ansible.
Output
Your expected output was just Hello World.
To make the testing process east I have changed the output a little like below
Hello, World instance id of this server is {instanceid}
