Create a Key Pair

To use Application Discovery Service with EC2 instances, you must create a key pair. AWS uses public-key cryptography (key pairs) to secure the login information for EC2 instances.

If you haven't created a key pair already, you can create one using the Amazon EC2 console. If you plan to launch instances in multiple regions, create a key pair in each region. For more information, see Regions and Availability Zones (Linux) and Amazon EC2 Key Pairs.
