Database Migration Service

AWS DMS provides one-time migration and continuous replication of your database records and data structures to AWS.

AWS Database Migration Service (AWS DMS) can be used to migrate data - from your database that is - on-premises, - on an Amazon Relational Database Service (Amazon RDS) DB instance, - or in a database on an Amazon Elastic Compute Cloud (Amazon EC2) instance - to a database on an AWS service.

With AWS DMS, you can create a task that captures ongoing changes after you complete your initial migration to a supported target data store. This process is called ongoing replication or change data capture (CDC).

Scalability

AWS DMS uses Amazon EC2 instances as the replication instance.
You can scale up or down your replication instance, depending on utilization.
You have the option of enabling Multi-AZ which provides a replication stream that is fault-tolerant through redundant replication servers.
