Restrictions

RDS for Microsoft 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 restrictions designed to ensure the stability and security of RDS for Microsoft SQL Server.

RDS for Microsoft SQL Server DB instances are divided into two series: basic edition and high-availability edition. DB instances of different series have different function restrictions. For details, see section Product Function Comparison.
