Overview
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:

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