Setting up EC2 instance

1. Used the AWS console GUI

• Used latest AMI amzn-ami-hvm-2018.03.0.20180508-x86_64-gp2 (ami-14c5486b)
• Used default security group with all SSH inbound traffic open

2. Make sure your pem key has the proper permissions $ chmod 400 my-pem-key.pem

3. Update ssh config

Host ec2
    HostName ec2-##-###-###-##.compute-1.amazonaws.com
    User ec2-user
    IdentityFile ~/.ssh/my-pem-key.pem

4. Ssh into instance $ ssh ec2
