7. Copy the newly created SSH key pair once the instance is created.

Step 2: Accessing Compute Instance from a DevBox

1. Go to the DevBox and make a copy of the key pair.

2. Connect to the desired Compute instance using ssh and the new key pair:

ssh -i "path/to/private/key" username@instance-ip
