Create a Key Pair

Amazon AWS instance access key pairs are explained here.

External reference for the procedures to create (or import) a key pair: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/get-set-up-for-amazon-ec2.html#create-a-key-pair

This procedure describes how to create the em provisioning key pair:

Go to the EC2 console https://us-west-2.console.aws.amazon.com/ec2/v2/home.

Left tab -> Network and Security -> Key Pairs -> Create Key Pair

The key is created and the file containing the private key is automatically downloaded by your browser. The base file name is the name you specified as the name of your key pair, and the file name extension is .pem. Save the private key file in a safe place.
