The document discusses Azure Database Migration Service (Azure DMS) which provides a seamless solution for migrating on-premises databases like SQL Server and Oracle to the cloud. It outlines the Azure database migration journey including assessing databases, transforming schemas, fixing issues, and migrating data. Azure DMS supports lift and shift, scale, and minimal downtime migrations using techniques like full data loads, continuous sync between on-premises and cloud, and eventually cutting over to the cloud database.
