Explanation

For a two-node SAP SCS cluster, the best DR strategy is to use a cloud provider's replication service, such as Azure Site Recovery, to replicate VMs and their disks to a secondary region. You must also replicate shared file systems, reconfigure the cluster (e.g., Pacemaker) to work with the replicated infrastructure, and ensure that the shared directories are available in the DR SAP Central Services The SAP central services contain enqueue and message server, which is one of the SPOF of your SAP application. In an SAP system, there can be only one such instance, and it can be configured for high availability. Configuring high availability for SAP Central Services protects resources and processes from local incidents. To achieve DR for SAP Central Services, you can use Azure Site Recovery. Azure Site Recovery replicates VMs and the attached managed disks. https://learn.microsoft.com/en-us/azure/sap/workloads/disaster-recovery-sap-guide
