Before you can start working with a Preinstalled AMI, you need to ensure that you fulfill the following prerequisites.
SAP S-User Account
AMIs are based on BYOL (Bring your own license) model. You will need to provide your own SAP Licenses. For that, your need to ensure that you own a valid S-User in SAP Service Marketplace with authorizations to request a SAP License Key.
Your AMI should run in a Virtual Private Cloud (VPC) within your AWS Account. AWS provides a default VPC that you can use for that purpose, or you can use your own VPC in case that you have an existing one.
Amazon EC2 uses public key cryptography to encrypt and decrypt login information. To be able to login into your newly created EC2 instance, you must create a new AWS Key Pair from the AWS Console, or ensure that you select the “Create a new Key Pair” option during the AMI deployment.
