The document discusses AWS Database Migration Service (DMS), which allows users to easily migrate databases to AWS. DMS supports homogeneous migrations between databases like MySQL as well as heterogeneous migrations between SQL and NoSQL databases. It can replicate data for disaster recovery and create read replicas. DMS has migrated over 75,000 databases for customers across many use cases from database upgrades to data warehouse migrations. It supports validation of migrations and can use AWS Snowball for large offline migrations.
