What Is SAP on Azure?
SAP applications form the basis of many enterprise operations, including those of multinational companies. The enterprise resource planning (ERP) applications that SAP provides are highly complex and capable of providing the scalability and analytics that are necessary for many organizations. As organizations move to the cloud it is key that they can take these applications with them which is why Microsoft has partnered with SAP on Azure.
Included in this partnership is support for the following SAP solutions:
- SAP HANA
- SAP S/4HANA
- SAP BW/4HANA
- SAP NetWeaver
- SAP Hybris
- SAP Cloud Platform

SAP Solutions Provided on Azure
To support moving enterprise operations to the cloud, Azure provides support for the following SAP solutions.
HANA is a relational database management system (RDBMS) built on column-oriented, in-memory operations. You can use it as an application database to perform real-time analytics, gather business intelligence, or centralize your operations. In Azure, HANA runs on a single instance.
Azure supports SAP HANA with:
- On-demand, SAP-certified virtual machines (VMs) with up to 12TB memory
- SAP HANA optimized instances with up to 20TB storage
- Scaling up to 60 or 120TB supported by TDIv4 or TDIv5 authorization
- Service level agreements (SLAs) for 99.99% availability
S/4HANA is an ERP suite built on the HANA database. It includes built-in features for financial analytics, supply chain management, manufacturing management, research and development operations, and sales operations. On Azure, you can implement a new S/4HANA deployment or migrate your existing SAP Business Suite deployment.
Azure supports SAP S/4HANA with:
- Remote connectivity via ExpressRoute for Fiori-based applications
- An SLA for 99.99% availability with instances in two Availability Zones (AZs)
- High speed, low recovery time backups
- Operations based on RedHat Enterprise Linux or SUSE Linux Enterprise servers
BW/4HANA is a data warehouse for business insights built on the HANA database. It includes features for simplified modeling and administration of change requests, integration of a wide range of data sources, an intuitive user interface, and real-time data processing.
Azure supports SAP BW/4HANA with:
- Operations optimized for SAP BW and analytics
- The ability to scale operations to 15 nodes with 4TB of storage per instance
- Instances that are SAP-certified for BW/4HANA
NetWeaver is a solution you can use as a platform for application integration and development or as an application server. It enables you to centrally develop, provision, and manage your applications regardless of whether they are SAP applications. You can use it to customize existing SAP solutions or to integrate your solutions with SAP.
Azure supports SAP NetWeaver with:
- On-demand VMs with attachable storage for non-production environments
- SLAs guaranteeing 99.95% availability for multiple VMs or 99.99% availability for a single VM
- SAP Certified operations on RedHat Enterprise Linux, SUSE Linux Enterprise, or Windows servers
Hybris is a set of solutions designed to help you ensure end-to-end customer engagement. It includes products for commerce, revenue and billing, sales, service, and marketing. You can use Hybris in Azure to create automated, on-demand VM operations for your customer-facing business units.
Azure supports SAP Hybris with:
- High availability and disaster recovery tools for business continuity
- SLAs guaranteeing 99.95% availability for multiple VMs or 99.99% availability for a single VM
- Operations certified to run on SAP NetWeaver-certified VMs
- Ability to run the SAP Hybris Commerce platform (v5.x or 6.x) on Oracle databases, SQL Server, or Windows Server
SAP Cloud Platform
Cloud Platform is a platform as a service (PaaS) solution that you can use to connect on-premises and cloud-based SAP resources. Cloud Platform is designed to enable you to build and extend your applications with open protocols. It is based on Cloud Foundry and can be layered on top of Azure resources.
Azure supports SAP Cloud Platform with:
- The ability to speed application development using Azure Storage and Azure Event Hubs
- Distribution of applications relying on SAP ERP data
- Support in five locations, including W Europe, W US 2, E US, Japan E, and SE Asia
Why Use SAP on Azure?
Combining your SAP and Azure operations can provide several benefits that are difficult to obtain with SAP or Azure alone. These include greater flexibility of operations, scalability, and integration of solutions.
Azure Is Hybrid
Azure offers support for hybrid operations beyond connectivity and infrastructure. It enables you to consistently perform operations regardless of platform, including identity management, application development, and security. Native and third-party integrations support these capabilities.
Azure Can Use Bare Metal for HANA
You can deploy HANA to VMs or bare metal servers in Azure. This enables you to ensure that resources are maintained in isolation with dedicated hardware. These servers come built-in with infrastructure for storage, compute, and networking. Additionally, bare metal servers are certified for HANA Tailored Data Center Integration.
Easy Integration of SAP and Microsoft Products
A long term partnership between Microsoft and SAP provides significant support for integrated solutions. For example, both Power BI and Office 365 support the use of SAP HANA. Additionally, both vendors use open standards and interfaces for data exchange, including OData. This enables you to integrate products smoothly with no need for data transformation.
Almost 100% Availability
Azure enables you to spread operations and data redundancies across AZs. Data is automatically replicated for durability and availability. You can also create additional backups or select geo-redundant storage for disaster recovery and failover protection.
SAP on Azure Migration Tactics
When moving SAP operations to Azure, several migration options are available. The option best suited to your migration depends on the size of your deployment and your ability to tolerate downtime.
Export / Import
Exporting data from your existing system and importing it to your new deployment is the traditional method for migration. This process compressed your database size to between 20-40% of the original size and can help you compensate for lower transfer speeds.
This method is customizable and can be used for heterogeneous migrations. The downside of this method is that your systems may need to be paused during export and there is no way to sync changes.
Database Backup / Restore
The backup and restore are similar to export/import except that it can only be performed on like (homogeneous) systems. To use this method, you can perform a new backup of your systems or use existing backups. You then use the new system’s built-in restore capabilities to apply that back up as though it came from the new system originally.
The downside of this method is that you must have identically configured systems to avoid restoration issues. Additionally, this method requires large files, can strain Internet connections, and doesn’t account for system changes post backup.
Database Backup / Restore with Log Shipping
This method extends the above method by adding log shipping, which helps you capture changes since the backup. Using this method enables you to move the bulk of your system data without requiring significant downtime. After the backup is restored, your logs, which have been capturing changes since the backup, are synched to create a 1:1 duplicate.
Using backup and restore with log shipping can grant greater flexibility for when you transfer workloads since the log sync can be left active. This enables you to switch during the lowest impact time or to create a failover in the cloud.
Migration through data transfer involves manually or automatically transferring data between systems. This method requires a high bandwidth connection and typically includes the use of a data replication tool like AzCopy. Data transfers are best used when you don’t need to replicate your entire system, only select data or applications.
SAP on Azure with NetApp Azure Files
Azure NetApp Files is a Microsoft Azure file storage service built on NetApp technology, giving you the file capabilities in Azure even your core business applications require.
