If you are planning to deploy Amazon RDS for SQL Server Developer Edition, one detail is easy to miss: this is not a license-included offering. You are expected to bring your own SQL Server Developer licensing entitlement when you create the instance. This little nugget of information came as a shock when I tried to build a Developer RDS instance.
This matters because many teams probably assume “Developer Edition” means “free everywhere.” The software edition itself is free from Microsoft for development and test use, but that does not mean AWS is packaging it as a standard license-included RDS option.
