Purpose

This document describes how to configure the SAP system on the public cloud to protect applications from a single point of failure (SPOF). It also explores how to migrate local features to the public cloud platform and improve SAP installation technologies to maximize the reliability of SAP deployment.

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.
