Microsoft SQL Server Constraints¶
RDS for SQL Server only supports DB instances under the License Included model and does not support "bring your own license" (BYOL). After a DB instance is created, it contains the Microsoft SQL Server software license.
Table 1 shows the constraints designed to ensure the stability and security of RDS for SQL Server.
Microsoft SQL Server DB instances are classified into three types: single, primary/standby, and cluster. Different types support different functions. For details, see Function Comparison.
