AWS Database Migration Service (AWS DMS) is a cloud service that can easily migrate relational databases, data warehouses, NoSQL databases, and Other types of data storage.
You can use AWS DMS to migrate data to the AWS cloud, between local instances (via AWS cloud settings), or between a combination of cloud and local settings.
Support incremental replication to reduce downtime.
3. Database types supported by DMS
AWS DMS supports almost all of today's most popular DBMS engines as data sources, including Oracle, MicrosoftSQLServer, MySQL, MariaDB, PostgreSQL, DB2LUW, SAP, MongoDB, and Amazon Aurora.
AWS DMS provides a wide range of available target engines, including Oracle, MicrosoftSQLServer , PostgreSQL, MySQL, Amazon Redshift, SAPASE, Amazon S3, and Amazon DynamoDB. It

AWS Database Migration Service can help you migrate your database to AWS easily and safely at a low cost. You only pay for the replication instance and additional log storage.
Each database migration instance contains enough storage for swap space, replication logs, and data cache, and these are free for most replication and inbound data transfers.
If the target of the database migration is Amazon Aurora, Amazon Redshift, Amazon DynamoDB or Amazon DocumentDB (compatible with MongoDB), you can use DMS for six months for free.
