Step 1: Launch an Amazon EC2 Instance

When your DynamoDB Accelerator (DAX) cluster is available, you can launch an Amazon EC2 instance in your default Amazon VPC. You can then install and run DAX client software on that instance.

  1. Sign in to the AWS Management Console and open the Amazon EC2 console at

  2. Choose Launch Instance, and do the following:

    Step 1: Choose an Amazon Machine Image (AMI)

    • At the top of the list of AMIs, find the Amazon Linux AMI and choose Select.

    Step 2: Choose an Instance Type

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

    • Choose Next: Configure Instance Details.

    Step 3: Configure Instance Details

    • For Network, choose your default VPC.

    • Choose Next: Add Storage.

    Step 4: Add Storage

    • Skip this step by choosing Next: Tag Instance.

    Step 5: Tag Instance

    • Skip this step by choosing Next: Configure Security Group.

    Step 6: Configure Security Group

    • Choose Select an existing security group.

    • In the list of security groups, choose default. This is the default security group for your VPC.

    • Choose Next: Review and Launch.

    Step 7: Review Instance Launch

    • Choose Launch.

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

    • If you do not 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 later 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.

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

  5. In the console navigation pane, choose EC2 Dashboard and then 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 for the next step (Step 3: Configure Your Amazon EC2 Instance).


It takes a few minutes for your Amazon EC2 instance to become available. In the meantime, you can proceed to Step 2: Create an IAM User and Policy and follow the instructions there.
