## Prerequisites
<a name="prerequisites"></a>

Before you can start setting up and using AWS ParallelCluster, make sure that you've completed the following prerequisites.

### Sign up for an AWS account

To get started with AWS, you need an AWS account. For information about creating an AWS account, see [Getting started with an AWS account](https://docs.aws.amazon.com//accounts/latest/reference/getting-started.html) in the *AWS Account Management Reference Guide*.

### Create a key pair

To deploy clusters, AWS ParallelCluster launches Amazon EC2 instances to create the cluster head node and compute nodes. To perform cluster tasks, such as running and monitoring jobs, or managing users, you must be able to access the cluster head node. To verify you can access the head node instance using SSH, you must use an Amazon EC2 key pair. To learn how to create a key pair, see [Create a key pair](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/get-set-up-for-amazon-ec2.html#create-a-key-pair) in the *Amazon Elastic Compute Cloud* User Guide for Linux Instances.
