21

You are the database administrator for a global e-commerce company. They run a mission-critical application on Azure SQL Database in the Business Critical tier. The database is 2 TB and experiences high write throughput. The current setup uses an auto-failover group with a secondary in the same region (West US) for high availability. The client application uses the auto-failover group listener with ReadScale=1 to route read-only queries to the secondary. Recently, during a regional outage that affected West US, the failover to the secondary succeeded, but the application experienced significant performance degradation and many timeouts for read operations. Investigation reveals that the secondary replica was overwhelmed with read traffic after failover. The business requires an RTO of 30 seconds and RPO of 5 seconds. The application must be able to handle read-heavy workloads even during a failover. You need to recommend a solution to improve read scalability and disaster recovery without changing the application code. What should you do?
