If you have decided that your enterprise business running in SAP will be deployed in MS Azure – then you have landed on the right place.
SAP customers run SAP deployments of all sizes on Azure—including SAP NetWeaver, SAP S/4HANA, SAP BW/4HANA, SAP BI, and SAP HANA in scale-up and scale-out scenarios. Now, it is always better to follow a planning guide/checklist for the same.
For decision on Sizing, H/W platform, you can consider my earlier blogpost.
SAP and Microsoft work in partnership to provide a clear roadmap for enterprise customers - who want to innovate in the cloud. The SAP on Azure Architecture Guide describes a set of guiding principles to ensure the quality of SAP workloads running on Azure. This is basically based on Microsoft Azure Well-Architected Framework, but the recommendations are specific to deployments of SAP solutions. It leverages the five pillars of excellence:
Cost
DevOps
- Automation
- Monitoring
Resiliency
Scalability, and
Security.
Reference Architecture for SAP solutions running on MS Azure
Deploying these reference architecture requires appropriate licensing of SAP products and other non-Microsoft technologies.
