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.
SAP Additional Information
AMIs will be deployed in your own AWS Account. If you don't have one yet, you can create a new one by following the steps in Create an AWS Account in the AWS Portal. Have your credit card handy.
AWS Additional Information
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.
AWS VPC Additional Information
If you don't have a VPC yet, you can follow the steps in the AWS Administration Guide to create one: https://docs.aws.amazon.com/directoryservice/latest/admin-guide/gsg_create_vpc.html
