AWS Data Migration Service Overview AWS Data Migration Service (AWS DMS) is a cloud service by AWS that helps you migrate data across 20+ databases and analytic engines. It allows you to actively manage data replication to AWS, ensuring fast and secure migration of your database and analytical workloads with zero data loss. DMS supports various data types, such as relational database structures, NoSQL data formats, semi-structured documents, large objects (LOBs), and primitives like integers, floats, strings, dates, and booleans.
AWS ETL tools , such as AWS DMS offer capabilities extend beyond one-time data migration, allowing for continuous data replication. It operates by gathering changes from the database logs through the native API of the database system. This enables you to handle ongoing changes effectively, synchronizing source and target.
