Amazon RDS for SQL Server Multi-AZ Support

Amazon RDS for SQL Server now supports Multi-AZ deployments using Always On Availability Groups for SQL Server Developer Edition. This feature maintains a synchronous standby replica in a different Availability Zone and provides automatic failover during infrastructure failure.

You can use this feature to build and test high availability configurations in non-production environments using Developer Edition, which includes all the functionality of Enterprise Edition at no license cost.

What to do

  • Validate your high availability architecture
  • Test failover behavior
  • Develop against production-equivalent configurations

Multi-AZ with Always On Availability Groups is available on SQL Server Developer Edition major versions 2019 and 2022, and on SQL Server 2025 Enterprise Developer Edition. SQL Server 2025 Standard Developer Edition does not support this feature.
