+- The SAP S/4HANA Fully-Activated Appliance 2023 FPS00 installation media and the SWPM must be stored in an S3 bucket (instructions see below).
 - The default EBS volumes provisioned by Launch Wizard are not appropriately sized for an S/4HANA FAA installation. During the installation, the package increases the size of these volumes to accommodate the storage requirements for data, logs, and media of the FAA system. To enhance performance and reduce provisioning time, it also boosts throughput and IOPS, which can be manually scaled down after the installation. Attach the provided [IAM Policy](iam_s4h_faa_policy.json) to the **AmazonEC2RoleForLaunchWizard** role to grant the *ec2:ModifyVolume* permission.
