After completing the initial configurations, you can connect to the RDS for SQLServer instance through a SQL Server client or your application by configuring the connection address, port number, and account information. The SQL Server client and your application can be deployed on ECS or a local computer.

If you are connecting from ECS to RDS through the intranet address, make sure that:
  • The ECS and RDS instances are both in the classic network or in the same VPC.
  • You have added the ECS intranet address to the RDS whitelist.
