SAP applications serve as the backbone of many businesses, providing much-needed functionality for operations such as finance, sales, and supply chain management. However, as businesses evolve, so too must their infrastructure. This is where migration to Microsoft Azure comes into play.
Microsoft Azure allows businesses to modernize and extend SAP workload capabilities with complete reliability and optimum performance. Azure ensures superior service levels, business continuity, global scalability, and simplified management for SAP workloads. In this article, you’ll learn how to design and implement an SAP migration to Azure.
Evaluating SAP systems for migration
Before the actual migration process begins, it’s important to evaluate SAP systems to understand infrastructural requirements. This initial assessment identifies the SAP workloads that are compatible with Azure, as well as the ones that need optimization. It includes reviewing the SAP HANA database compatibility, any SAP NetWeaver compatibility issues, virtual machines, networking, storage, and security needs.
Create a detailed migration plan
Creating a detailed migration plan is the next logical step. At this stage, keep in mind the architecture and data center options Azure has to offer. The migration plan should specifically break down each SAP module to be migrated, and the order in which they should be migrated.
The migration approach should consider,
- Operating system
- Size of the SAP system
- Downtime constraints
- Network bandwidth
Designing and Building the Azure environment
Your Azure environment will need to be set up to host the SAP applications. The design and deployment should take into account factors like network design, security, data governance, and resource allocation.
You might want to use Azure Virtual Networks, for example, to provide network isolation for your SAP system. For security, Azure Active Directory could be used to control access.
Migrating the SAP Workloads
The actual migration of the SAP systems is then carried out. This can be done using different methods, such as Azure Site Recovery for an automated migration or using a special tool for SAP HANA migrations – SAP HANA Large Instances.
In the SAP HANA Large Instances method, the SAP HANA database is backed up and restored on Azure. Azure NetApp Files or Azure premium storage is being used as a target.
Post-Migration Processes
Post-migration, you should verify if the system is working as expected. Security checks and performance tests should be done to ensure system performance and stability. You can also make use of Azure’s built-in features for monitoring, scaling, and optimizing the migrated SAP systems.
In summary, the design and implementation of an SAP migration to Azure involves strategically assessing the current SAP system, planning the migration, setting up the Azure environment, carrying out the migration, and then validating the system post-migration.
Please note that a professional who will be taking AZ-120 Planning and Administering Azure for SAP Workloads exam should be proficient in all the topics mentioned in this post, and also have hands-on experience in administering Azure and managing SAP workloads hosted on Azure.
Preparing for the AZ-120 exam requires a comprehensive understanding of Azure services along with SAP architecture and implementations. Always use trusted resources and verified study materials for a thorough understanding of the syllabus matter. The more hands-on experience you have with Azure and SAP, the better you will perform in the actual examination.
Remember, any migration is not only a process but also an opportunity for companies to optimize their operations via new technologies. Migrating SAP systems to Azure is no different and can lead to improved performance, flexibility, and scalability.
