Manual deployment of SAP HANA on AWS with high availability clusters

Architecture

This guide helps you configure high availability clusters on SLES or RHEL operating systems for your SAP HANA databases, deployed on Amazon EC2 instances in two different Availability Zones (AZs) within an AWS Region.

Operating systems

You can deploy your SAP workload on any of the following operating systems:

SLES for SAP and RHEL for SAP with HA and US are available in the AWS Marketplace with an hourly or an annual subscription model.

SUSE Linux Enterprise Server for SAP Applications (SLES for SAP)

SLES for SAP provides additional benefits, including Extended Service Pack Overlap Support (ESPOS), configuration and tuning packages for SAP applications, and High Availability Extensions (HAE). See the SUSE SLES for SAP product page.AWS strongly recommends using SLES for SAP instead of SLES for all your SAP workloads.

If you plan to use Bring Your Own Subscription (BYOS) images provided by SUSE, ensure that you have the registration code required to register your instance with SUSE to access repositories for software updates.

Red Hat Enterprise Linux (RHEL)

RHEL for SAP with HA and US provides access to Red Hat Pacemaker cluster software for High Availability, extended update support, and the libraries that are required to configure pacemaker cluster. For details, see the RHEL for SAP Offerings on AWS FAQ in the Red Hat knowledge base.

If you plan to use the BYOS model with RHEL, either through the Red Hat Cloud Access program or another means, ensure that you have access to a RHEL for SAP Solutions subscription. For details, see Overview of the Red Hat Enterprise Linux for SAP Solutions subscription in the Red Hat knowledge base.

The correct subscription is required to download the required packages for configuring the Pacemaker cluster.
