Log in to the AWS RDS SQL Server instance using SQL Server Management Studio (SSMS) and get the actual server name using the following T-SQL query. So, we have to get the actual SQL Server instance name of the RDS SQL Server instance and create an alias (CNAME entry) in DNS. The instance throws an error if you try to create the subscriber with the endpoint of the RDS SQL Server instance. ![]() In SQL Server transactional replication, we cannot create a subscriber using the endpoint. ![]() Log in to your on-premises SQL Server instance, Open SQL Server management studio (SSMS), and test the connectivity to the AWS RDS SQL Server using the endpoint and the password you set for admin user while creating the AWS RDS SQL Server database instance. Once the database status changes to Available from Creating, click on the database instance and note the database endpoint that will be used to connect the AWS RDS SQL Server instance. Review your settings and click on the Create database button. It is best practice to keep the database instance in the private subnet and access it using the private network by not assigning public endpoint and exposing to the outside world. If you want to connect the RDS database instance from machines that are outside of the VPC network using private IP then establish a VPN connection between your on-premises network and the AWS VPC.Ĭhoose Yes if you want to access the database instance from machines outside your VPC network without establishing a VPN connection between your on-premises network and the AWS VPC. If you want to access the RDS database instance within the VPC network, select No. This RDS SQL server instance will be used as subscriber in the transactional SQL replication.Ĭhoose the engine type as SQL Server and the edition, version of your choice.Įnter the name of the RDS DB instance and the password for the admin user.Ĭhoose the VPC network in which you want to launch the DB instance. Click on the Create database button and then create a database, as shown in the below image. Login to the AWS management console and navigate to the RDS console. Adding the AWS RDS SQL Server instance as a subscriber.Configuring the distributor and the publisher at on-premises SQL Server.Creating the DNS entries with the actual name of RDS SQL Server instance.The following are the high-level steps involved in configuring transactional SQL replication between on-premises SQL Server and AWS RDS for SQL Server. In this article, we will review how to migrate the data from on-premises SQL Server to AWS RDS for SQL Server using transactional replication. There are several ways to migrate data from on-premises SQL Server to AWS RDS for SQL Server and transactional replication is one among them.Ĭonfiguring transactional replication between the on-premises SQL Server instance and AWS RDS SQL Server is different from configuring transactional replication between two on-premises SQL Servers. ![]()
