Before you begin, you will need to obtain an Amazon AWS account if you do not already have one. Select the "Sign Up Now" button on the AWS home page. During the account creation process, you will be given an Access Key ID and an Access Secret Key. Please be sure to record them both, as you will need them to access the VAT AMIs.
Here are step-by-step instructions for running the VAT AMIs. Use the AWS Console to locate the public AMIs:
Right-click on the image entries and select "Launch Instance". The launch wizard will guide you through selecting the number of instances to launch, the availability region in which to launch the instance(s), and the SSH keypair to use for login. You may use your default SSH keypair or create a new one. When you select the security group, you can decide whether you wish to support the built-in web servers. If you wish to do so, then create a security group that has the following rules defined:
Port Source Status 22 (SSH) 0.0.0.0/0 Open 80 (HTTP) 0.0.0.0/0 Open
You may also defer the creation of these rules till later. Just create a security group that has the SSH port open at the time of instance creation. Then, log in to your instances using the following command:
ssh -i path_to_key.pem email@example.com
Please refer to the VAT documentation for more details.
