Starting March 20, 2026, SAP BTP ABAP environment introduces the multi-availability zone (multi-AZ) option for ABAP environment instances, further strengthening system resilience.
When enabled, the ABAP runtime components of an SAP BTP ABAP environment instance are distributed across multiple availability zones within a region. In parallel, the SAP HANA Cloud database is configured in a high-availability setup with a primary and a secondary instance in different availability zones, using synchronous replication. This ensures that, in case of infrastructure failures, workloads can continue running with minimal disruption.
Compared to the default single availability zone setup, the multi-AZ option provides:
- Distribution of ABAP application servers across availability zones
- Higher prioritization during recovery scenarios
- Automatic failover to a secondary database instance
- Improved resilience in case of availability zone outages
It is important to note that the multi-availability zone option does not affect ABAP runtime costs (ACUs). However, persistence layer costs increase, as the SAP HANA Cloud database is deployed with an additional secondary instance (HCUs).
The option is configured at SAP BTP ABAP environment instance level and is particularly relevant for scenarios with higher availability and resilience requirements.
