You must have a key pair or a PEM key to launch your AWS instance. This is a combination of a public key that AWS stores and a private key that you store. Used together, they allow you to securely connect to your Elasticsearch by Ryft instance.
From the EC2 console, select your instance, and then click Launch. This window displays.
You can choose an existing key pair, create a new key pair, or choose to proceed without one. If you want to use an existing key pair, then select one from the bottom drop-down list. Make sure you select the checkbox to acknowledge the message; the Launch Instances button is enabled. Click Launch Instances.
The Launch Status window displays.
Click View Instances to view your instance from the EC2 Console.
