1. Launch an EC2 instance. Enter desired name, make a new key pair.

2. Your instance will be created. Connect to your newly made instance via EC2 connect or SSH.

3. Fire the command “sudo apt-add-repository ppa:ansible/ansible”.

4. Run the command “sudo apt update”.

5. Run the command “sudo apt install ansible”.

6. Run “cat /etc/ansible/hosts” to check whether ansible is installed or not.
