In today’s cloud-centric world, leveraging robust and reliable operating systems is crucial for businesses. One such powerful combination is SUSE Enterprise Linux on Azure. This blog delves into the various aspects of using SUSE Enterprise Linux, particularly the High Availability (HA) extension, on Azure.

SUSE Distributions Supported on Azure

Pricing and Licensing Models

SUSE has three offerings in Azure:

BYOS
SUSE Image with patching support
24×7 support

When it comes to pricing, the Azure pricing calculator provides various options. For instance, for a B2as machine with SUSE Linux Enterprise + 24/7 Support, PAYG, the cost is approximately $47.45 per month as of writing this blog.

You can select the desired image during the installation, and the Azure marketplace provides detailed information on what is offered under each SUSE image deployed through the marketplace.

High Availability Extension

The High Availability extension is a critical component for businesses that require continuous uptime and disaster recovery solutions. If you purchase the SUSE Linux Enterprise Server for SAP, the High Availability extension is included. However, if you opt for the standard SUSE Linux Enterprise Server through the Azure marketplace, you cannot add the High Availability extension. In such cases, you will need to use the BYOS (Bring Your Own Subscription) model.

SUSE Enterprise Linux for SAP comes with several features designed to enhance performance and reliability, including:

A full High Availability / Disaster Recovery solution
SAP HANA System Replication automation agents
SAP HANA Firewall with automated setup
A KMIP-compliant key server for remote storage
SAP configuration and tuning packages

Azure market place provides the detail on what is offered under each SUSE image deployed through the marketplace.
