DMS Overview
AWS Database Migration Service (AWS DMS) is a cloud service that makes it easy to migrate relational databases, data warehouses, NoSQL databases, and other types of data stores to migrate data into the AWS Cloud or between combinations of cloud and on-premises setups
DMS Benefits

- the migration can be up and running within minutes of starting the AWS DMS configuration process.
DMS Features
- scale up or scale down the migration resources as needed to match your actual workload demands
- uses a pay as you go model
- manages all of the infrastructure that supports the migration server, including hardware and software, software patching, and error reporting
