2- Create your own key-pair and use in EC2/main.tf

3- Make sure to pass your credentials correctly in main.tf file provider block

4- Comment the backend in RemoteStateFile.tf and change S3 name to a unique one

Bonus

• Added Ansible files to configure EC2 machines using configuration management tool tou use it instead of provisioner in Terraform
• Ansible uses 1 of the EC2 public machines as a bastion host to connect to the private ones
• Installs Nginx on all machines then copy a script and run it on the machines
• Pass any script to the ansible files to cinfigure the machines as you like
• The provided IPS are dynamic not static so make sure to clear the all-ips file and use the IPS generated on applying terraform
