Migrate SQL Server to AWS

Microsoft SQL Server Always On availability groups provide a high availability (HA) and disaster recovery (DR) solution for SQL Server. An availability group consists of a primary replica that accepts read/write traffic, and up to eight secondary replicas that accept read traffic. An availability group is configured on a Windows Server Failover Cluster (WSFC) with two or more nodes.

Microsoft SQL Server Always On distributed availability groups provide a solution to configure two separate availability groups between two independent WFSCs. The availability groups that are part of the distributed availability group don’t have to be in the same data center. One availability group can be on premises, and the other availability group can be on the Amazon Web Services (AWS) Cloud on Amazon Elastic Compute Cloud (Amazon EC2) instances in a different domain.

This pattern outlines steps for using a distributed availability group to migrate on-premises SQL Server databases that are part of an existing availability group to SQL Server with availability groups set up on Amazon EC2. By following this pattern, you can migrate the databases to the AWS Cloud with minimal downtime during cutover. The databases are highly available on AWS immediately after the cutover. You can also use this pattern to change the underlying operating system from on-premises to AWS while keeping the same version of SQL Server.
