Amazon RDS for SQL Server now supports Single-AZ Read-Replicas using Always On Availability Groups (AOAG) for Enterprise Edition in Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD. This provides customer the option to create up to 15 number of read replicas from a Single-AZ Enterprise Edition source instance in the same region, or cross regions.
Customers can now use read replicas with a Single-AZ database instance, whereas previously database instances were required to be in the Multi-AZ configuration. Read replicas asynchronously replicate the database between the source database instance and the replica. This enhances availability and durability without compromising performance when Multi-AZ is not needed.
Single-AZ Read-Replicas on Enterprise Edition is now generally available in all Amazon Web Services regions where Amazon RDS for SQL Server is currently available.
Amazon RDS makes it simple to set up, operate, and scale SQL Server deployments in the cloud. See Amazon RDS for SQL Server Pricing for up-to-date pricing of instances, storage, data transfer and regional availability.
