About This Document

This document describes how to configure high availability (HA) and disaster recovery (DR) for SAP HANA deployed on the public cloud. HA and DR modes can prevent single points of failure (SPOFs), greatly improving the reliability of the SAP HANA system.

Note that this document cannot replace standard SAP installation documents. For more information about SAP deployment on the public cloud and public cloud technical components, see the operation guides of SAP and Huawei.

This document describes how to set up and configure the system replication for SAP HANA databases, but does not guide how to configure the high availability (HA) for databases in details, for example, using SQL Server Mirroring or Oracle Data Guard.
