The document conventions are as follows:

This document provides instructions to prepare resources (such as ECSs and network resources) on the public cloud platform, and install SAP S/4HANA in high availability (HA) mode. SAP S/4HANA is authorized in Bring Your Own License (BYOL) mode. In this mode, you must log in at SAP Support Portal Home and apply for a license.
This document cannot replace the standard SAP document. If you have any trouble in installing and using SAP S/4HANA due to its own problems, contact the SAP technical support.
This document is written based on the SUSE Linux OS. The deployment modes mentioned in the document are only for reference. Install SAP S/4HANA by referring to the standard SAP installation manual or based on sizing results and site requirements.
You have installed the SAP HANA database and the SAP HANA database is used as the background database to install SAP S/4HANA. For details about how to install SAP HANA, see the SAP HANA User Guide (Single Node).
For details about the official SAP installation guide and related notes, see the following documents:

The following table lists the mappings between application versions and operating systems.

**Table 1** Version mappings
Application Version	SLES 12 SP1	SLES 12 SP2	SLES 12 SP3	SLES 15
S/4HANA 1610	Supported	Supported	Supported	Supported
S/4HANA 1709	Supported	Supported	Supported	Supported
S/4HANA 1809	Not supported	Supported	Supported	Supported

The following table describes the mappings between versions of the OSs and Resource Agents as well as the OSs and SAP Connector.

Table 3 lists the required cloud services for deploying SAP S/4HANA in HA mode.

**Table 3** Required cloud services
Cloud Service Name	Description
Elastic Cloud Server (ECS)	SAP S/4HANA is deployed on ECSs.
Elastic Volume Service (EVS)	All the SAP S/4HANA ECSs have EVS disks attached.
Virtual Private Cloud (VPC)	All SAP S/4HANA ECSs belong to the same VPC. They are isolated using subnets and security groups in the VPC for network security.
Image Management Service (IMS)	When creating an SAP S/4HANA ECS, select a proper public image, for example, SUSE Linux Enterprise Server (SLES) 12 SP1 for SAP.
Volume Backup Service (VBS)	VBS backs up EVS disks and uses the backups to restore original EVS disks, ensuring user data accuracy and security.
Scalable File Service (SFS)	SFS provides high-performance file storage that is scalable on demand. It can be accessed by multiple ECSs.
