Question
You are planning high availability for an SAP environment on Azure. The SAP environment will use datacenters in to different zones. Testing shows that the latency between the two zones supports synchronous DBMS replication. You need to design a solution to ensure that SAP services are available if an Azure datacenter within a zone fails. The solution must meet the following requirements:
- Provide automatic failover
- Minimize costs
Which high availability configuration meet the requirements?
Options
- AAzure Availability Zones with an active/passive deployment
- BAzure Site Recovery
- CAzure Availability Sets with active/passive clustering
- DAzure Availability Sets with active/active clustering

Explanation
Azure Availability Zones provide physical separation within an Azure region across different datacenters with independent power, cooling, and networking. This protects against datacenter- level failures within the region. Active/passive deployment is a common pattern for SAP database high availability, where one node is active and the other is on standby, ready to take over automatically in case of failure. This supports automatic failover with minimal complexity and cost compared to active/active The latency between zones supports synchronous DBMS replication, which is essential for active/passive setups to maintain data consistency without data loss. Using Availability Zones ensures that both compute and storage resources (managed disks) are co-located within the same zone, improving performance and failover reliability.
