You have the option to migrate an existing 4.4.3 or latest on-premises Controller database to Aurora DB. The Controller might already reside in AWS, or in your data center.

Although the Controller already contains a MySQL database, you are recommended to migrate the MySQL database to Aurora because it offers replication, high availability, and elasticity. The Amazon Relational Database Service (RDS) tool handles provisioning, patching, backup, recovery, failure detection, and repair of the database. Also, Aurora DB offers encryption at rest, with encryption of all automated backups, snapshots, and replicas in the same cluster.

If your Controller is not already in AWS, then follow Migrate the Controller to migrate it. Once this is complete, you should have a Controller running on one or two EC2 instances in AWS, depending on whether or not your existing Controller deployment is high availability (HA), with the MySQL database hosted on those instances.
