A key pair is a set of credentials that you use to authenticate your identity to gain access to a computer. This step creates a key pair file called "cyent-key-pair" that you will use to access your EC2 instance. Ensure you keep the output file ‘cyent-key-pair.pem’ in a safe location.
aws ec2 create-key-pair --key-name cyent-key-pair --output text --query KeyMaterial > cyent-key-pair.pem
