Launching an Amazon EC2 Instance

Access to Neptune is limited to within the virtual private cloud (VPC) that the Neptune DB instance is in. The following steps launch an Amazon Elastic Compute Cloud (Amazon EC2) instance in your default Amazon VPC. If you created a Neptune DB instance in a different VPC, you should launch the EC2 instance in that VPC.

To launch an EC2 instance

    1. Choose an Amazon Machine Image (AMI):

      At the top of the list of AMIs, go to Amazon Linux AMI, and choose Select.

    2. Choose an Instance Type:

      1. At the top of the list of instance types, choose t2.micro.

  4. In the Select an existing key pair or create a new key pair window, do one of the following:

    • If you don't have an Amazon EC2 key pair, choose Create a new key pair and follow the instructions. You are asked to download a private key file (.pem file); you need this file when you log in to your Amazon EC2 instance.

    • If you already have an existing Amazon EC2 key pair, go to Select a key pair and choose your key pair from the list. You must already have the private key file (.pem file) available in order to log in to your Amazon EC2 instance.

  5. When you have configured your key pair, choose Launch Instances.

  6. Return to the Amazon EC2 console home page and choose the instance that you launched. In the lower pane, on the Description tab, find the Public DNS for your instance; for example:

    Make a note of this public DNS name, because you need it to connect to the instance.


It takes a few minutes for your Amazon EC2 instance to become available. Before you continue, ensure that the Instance State is running and that all of its Status Checks have passed.
