We're going to use OpenVPN for this example. They provide a free (for up to two users) AMI in the AWS marketplace, which has OpenVPN already installed and configured. You'll need to accept the terms and conditions for using this AMI. You can do so by visiting the AMI's marketplace page at https://aws.amazon.com/marketplace/pp/B00MI40CAE/.
You need to decide on a password, which will be your temporary admin password. We'll feed this password into a CloudFormation template and then change it after we create our stack.
You can use the default VPC for this example.
